- * Database independent query interface

- * The main "DB" class is simply a container class with some static

- * common to all parts of DB.
- *
- * The object model of DB is as follows (indentation means inheritance):
- * <pre>
- * DB           The main DB class.  This is simply a utility class
- *              with some "static" methods for creating DB objects as
- *              well as common utility functions for other DB classes.
- *
- * DB_common    The base for each DB implementation.  Provides default
- * |            implementations (in OO lingo virtual methods) for
- * |            the actual DB implementations as well as a bunch of
- * |            query utility functions.
- * |
- * +-DB_mysql   The DB implementation for MySQL.  Inherits DB_common.
- *              When calling DB::factory or DB::connect for MySQL
- *              connections, the object returned is an instance of this
- *              class.

-     * These modes are bitwised, so they can be combined using <kbd>|</kbd>
-     * and removed using <kbd>^</kbd>.  See the examples section below on how
-     * to do this.
-     *
-     * <samp>DB_PORTABILITY_NONE</samp>
-     * turn off all portability features
-     *
-     * This mode gets automatically turned on if the deprecated
-     * <var>optimize</var> option gets set to <samp>performance</samp>.
-     *
-     *
-     * <samp>DB_PORTABILITY_LOWERCASE</samp>
-     * convert names of tables and fields to lower case when using
-     * <kbd>get*()</kbd>, <kbd>fetch*()</kbd> and <kbd>tableInfo()</kbd>
-     *
-     * This mode gets automatically turned on in the following databases
-     * if the deprecated option <var>optimize</var> gets set to
-     * <samp>portability</samp>:
-     * + oci8
-     *
-     *
-     * <samp>DB_PORTABILITY_RTRIM</samp>
-     * right trim the data output by <kbd>get*()</kbd> <kbd>fetch*()</kbd>
-     *
-     *
-     * <samp>DB_PORTABILITY_DELETE_COUNT</samp>
-     * force reporting the number of rows deleted
-     *
-     * Some DBMS's don't count the number of rows deleted when performing
-     * simple <kbd>DELETE FROM tablename</kbd> queries.  This portability
-     * mode tricks such DBMS's into telling the count by adding
-     * <samp>WHERE 1=1</samp> to the end of <kbd>DELETE</kbd> queries.
-     *
-     * This mode gets automatically turned on in the following databases
-     * if the deprecated option <var>optimize</var> gets set to

-     * This mode gets automatically turned on in the following databases

-     * makes certain error messages in certain drivers compatible
-     * with those from other DBMS's
-     *
-     * + mysql, mysqli:  change unique/primary key constraints
-     *   DB_ERROR_ALREADY_EXISTS -> DB_ERROR_CONSTRAINT
-     *
-     * + odbc(access):  MS's ODBC driver reports 'no such field' as code
-     *   07001, which means 'too few parameters.'  When this option is on
-     *   that code gets mapped to DB_ERROR_NOSUCHFIELD.
-     *   DB_ERROR_MISMATCH -> DB_ERROR_NOSUCHFIELD
-     *
-     * <samp>DB_PORTABILITY_NULL_TO_EMPTY</samp>
-     * convert null values to empty strings in data output by get*() and
-     * fetch*().  Needed because Oracle considers empty strings to be null,
-     * while most other DBMS's know the difference between empty and null.

-/**
- * Base class for other PEAR classes.  Provides rudimentary
- * emulation of destructors.
- *
- * If you want a destructor in your class, inherit PEAR and make a
- * destructor method called _yourclassname (same name as the
- * constructor, but with a "_" prefix).  Also, in your constructor you
- * have to call the PEAR constructor: $this->PEAR();.
- * The destructor method will be called without parameters.  Note that
- * at in some SAPI implementations (such as Apache), any output during
- * the request shutdown (in which destructors are called) seems to be
- * discarded.  If you need to get any debug information from your
- * destructor, use error_log(), syslog() or something similar.
- *
- * IMPORTANT! To use the emulated destructors you need to create the
- * objects by reference: $obj =& new PEAR_child;

-phpFlickr Class 2.3.1
-Written by Dan Coulter (dancoulter@users.sourceforge.net)
-Project Homepage: http://www.phpflickr.com/
-Google Code Project Page: http://code.google.com/p/phpflickr/
-Released under GNU Lesser General Public License (http://www.gnu.org/copyleft/lgpl.html)
-For more information about the class and upcoming tools and applications using it,
-visit http://www.phpflickr.com/ or http://code.google.com/p/phpflickr/
-
-If you are interested in hiring me for a project (involving phpFlickr
-or not), feel free to email me.
-
-Installation instructions:
-1.  Copy the files from the installation package into a folder on your
-    server.  They need to be readible by your web server.  You can put 
-    them into an include folder defined in your php.ini file, if you 
-    like, though it's not required. 
-    
-2.  All you have to do now is include the file in your PHP scripts and 
-    create an instance.  For example:
-    $f = new phpFlickr();
-
-    The constructor has three arguments:
-    A.  $api_key - This is the API key given to you by flickr.com. This 
-        argument is required and you can get an API Key at:
-        http://www.flickr.com/services/api/key.gne
-        
-    B.  $secret - The "secret" is optional because is not required to 
-        make unauthenticated calls, but is absolutely required for the 
-        new authentication API (see Authentication section below).  You 
-        will get one assigned alongside your api key.
-    
-    C.  $die_on_error - This takes a boolean value and determines 
-        whether the class will die (aka cease operation) if the API 
-        returns an error statement.  It defaults to false.  Every method 
-        will return false if the API returns an error.  You can access 
-        error messages using the getErrorCode() and getErrorMsg() 
-        methods.
-        
-3.  All of the API methods have been implemented in my class.  You can 
-    see a full list and documentation here: 
-        http://www.flickr.com/services/api/
-    To call a method, remove the "flickr." part of the name and replace 
-    any periods with underscores. For example, instead of 
-    flickr.photos.search, you would call $f->photos_search() or instead 
-    of flickr.photos.licenses.getInfo, you would call 
-    $f->photos_licenses_getInfo() (yes, it is case sensitive).
-    
-    All functions have their arguments implemented in the list order on 
-    their documentation page (a link to which is included with each 
-    method in the phpFlickr clasS). The only exceptions to this are 
-    photos_search(), photos_getWithoutGeodata() and 
-    photos_getWithoutGeodata() which have so many optional arguments
-    that it's easier for everyone if you just have to pass an 
-    associative array of arguments.  See the comment in the 
-    photos_search() definition in phpFlickr.php for more information.
-    
-
-    
-Authentication:
-    As of this release of the phpFlickr class there is only one authentication method
-    available to the API.  This method is somewhat complex, but is far more secure and
-    allows your users to feel a little safer authenticating to your application.  You'll
-    no longer have to ask for their username and password.
-    
-    Authentication API - http://www.flickr.com/services/api/auth.spec.html
-        
-        I know how complicated this API looks at first glance, so I've tried to
-        make this as transparent to the coding process.  I'll go through the steps
-        you'll need to use this.  Both the auth.php and getToken.php file will
-        need your API Key and Secret entered before you can use them.
-        
-        To have end users authenticate their accounts:
-            First, setup a callback script.  I've included a callback script that 
-            is pretty flexible.  You'll find it in the package entitled "auth.php".  
-            You'll need to go to flickr and point your api key to this file as the 
-            callback script.  Once you've done this, on any page that you want to 
-            require the end user end user to authenticate their flickr account to 
-            your app, just call the phpFlickr::auth() function with whatever 
-            permission you need to use.
-            For example:
-                $f->auth("write");
-            The three permissions are "read", "write" and "delete".  The function
-            defaults to "read", if you leave it blank.  
-            
-            Calling this function will send the user's browser to Flickr's page to 
-            authenticate to your app.  Once they have logged in, it will bounce
-            them back to your callback script which will redirect back to the
-            original page that you called the auth() function from after setting
-            a session variable to save their authentication token.  If that session
-            variable exists, calling the auth() function will return the permissions
-            that the user granted your app on the Flickr page instead of redirecting
-            to an external page.
-        
-        To authenticate the app to your account to show your private pictures (for example)
-            This method will allow you to have the app authenticate to one specific
-            account, no matter who views your website.  This is useful to display
-            private photos or photosets (among other things).
-            
-            *Note*: The method below is a little hard to understand, so I've setup a tool
-            to help you through this: http://www.phpflickr.com/tools/auth/.
-                        
-            First, you'll have to setup a callback script with Flickr.  Once you've
-            done that, edit line 12 of the included getToken.php file to reflect 
-            which permissions you'll need for the app.  Then browse to the page.
-            Once you've authorized the app with Flickr, it'll send you back to that
-            page which will give you a token which will look something like this:
-                1234-567890abcdef1234
-            Go to the file where you are creating an instance of phpFlickr (I suggest
-            an include file) and after you've created it set the token to use:
-                $f->setToken("<token string>");
-            This token never expires, so you don't have to worry about having to
-            login periodically.
-            
-
-Using Caching:
-    Caching can be very important to a project.  Just a few calls to the Flickr API
-    can take long enough to bore your average web user (depending on the calls you
-    are making).  I've built in caching that will access either a database or files
-    in your filesystem.  To enable caching, use the phpFlickr::enableCache() function.
-    This function requires at least two arguments. The first will be the type of
-    cache you're using (either "db" or "fs")
-    
-    1.  If you're using database caching, you'll need to supply a PEAR::DB connection
-        string. For example: 
-        $flickr->enableCache("db", "mysql://user:password@server/database");
-        The third (optional) argument is expiration of the cache in seconds (defaults 
-        to 600).  The fourth (optional) argument is the table where you want to store
-        the cache.  This defaults to flickr_cache and will attempt to create the table
-        if it does not already exist.
-    
-    2.  If you're using filesystem caching, you'll need to supply a folder where the
-        web server has write access. For example: 
-        $flickr->enableCache("fs", "/var/www/phpFlickrCache");
-        The third (optional) argument is, the same as in the Database caching, an
-        expiration in seconds for the cache.
-        Note: filesystem caching will probably be slower than database caching. I
-        haven't done any tests of this, but if you get large amounts of calls, the
-        process of cleaning out old calls may get hard on your server.
-        
-        You may not want to allow the world to view the files that are created during
-        caching.  If you want to hide this information, either make sure that your
-        permissions are set correctly, or disable the webserver from displaying 
-        *.cache files.  In Apache, you can specify this in the configuration files
-        or in a .htaccess file with the following directives:
-        
-        <FilesMatch "\.cache$">
-            Deny from all
-        </FilesMatch>
-        
-        Alternatively, you can specify a directory that is outside of the web server's
-        document root.
-        
-Uploading
-    Uploading is pretty simple. Aside from being authenticated (see Authentication 
-    section) the very minimum that you'll have to pass is a path to an image file on 
-    your php server. You can do either synchronous or asynchronous uploading as follows:
-        synchronous:    sync_upload("photo.jpg");
-        asynchronous:   async_upload("photo.jpg");
-    
-    The basic difference is that synchronous uploading waits around until Flickr
-    processes the photo and returns a PhotoID.  Asynchronous just uploads the
-    picture and gets a "ticketid" that you can use to check on the status of your 
-    upload. Asynchronous is much faster, though the photoid won't be instantly
-    available for you. You can read more about asynchronous uploading here:
-        http://www.flickr.com/services/api/upload.async.html
-        
-    Both of the functions take the same arguments which are:
-        Photo: The path of the file to upload.
-        Title: The title of the photo.
-        Description: A description of the photo. May contain some limited HTML.
-        Tags: A space-separated list of tags to apply to the photo.
-        is_public: Set to 0 for no, 1 for yes.
-        is_friend: Set to 0 for no, 1 for yes.
-        is_family: Set to 0 for no, 1 for yes.
-        
-Replacing Photos
-    Flickr has released API support for uploading a replacement photo.  To use this
-    new method, just use the "replace" function in phpFlickr.  You'll be required
-    to pass the file name and Flickr's photo ID.  You need to authenticate your script
-    with "write" permissions before you can replace a photo.  The arguments are:
-        Photo: The path of the file to upload.
-        Photo ID: The numeric Flickr ID of the photo you want to replace.
-        Async (optional): Set to 0 for a synchronous call, 1 for asynchronous.
-    If you use the asynchronous call, it will return a ticketid instead
-    of photoid.
-
-Other Notes:
-    1.  Many of the methods have optional arguments.  For these, I have implemented 
-        them in the same order that the Flickr API documentation lists them. PHP
-        allows for optional arguments in function calls, but if you want to use the
-        third optional argument, you have to fill in the others to the left first.
-        You can use the "NULL" value (without quotes) in the place of an actual
-        argument.  For example:
-        $f->groups_pools_getPhotos($group_id, NULL, NULL, 10);
-        This will get the first ten photos from a specific group's pool.  If you look
-        at the documentation, you will see that there is another argument, "page". I've
-        left it off because it appears after "per_page".
-    2.  Some people will need to ues phpFlickr from behind a proxy server.  I've
-        implemented a method that will allow you to use an HTTP proxy for all of your
-        traffic.  Let's say that you have a proxy server on your local server running
-        at port 8181.  This is the code you would use:
-            $f = new phpFlickr("[api key]");
-            $f->setProxy("localhost", "8181");
-        After that, all of your calls will be automatically made through your proxy server.
-            
-
-That's it! Enjoy the class.  Check out the project page (listed above) for updates
-and news.  I plan to implement file uploads and functions to aggregate data from
-several different methods for easier use in a web application.  Thanks for your
-interest in this project!
