 * To implement a filter, you need to define a class as an extension of

 * to which your filter is attached, PHP will pass the data through your
 * filter (and any other filters attached to that stream) so that the
 * data may be modified as desired. You must implement the methods
 * exactly as described below - doing otherwise will lead to undefined
 * behaviour.
 * </p>
 * intfilter
 * resourcein
 * resourceout
 * intconsumed
 * boolclosing
 * <p>
 * This method is called whenever data is read from or written to
 * the attached stream (such as with fread or fwrite).
 * in is a resource pointing to a bucket brigade
 * which contains one or more bucket objects containing data to be filtered.
 * out is a resource pointing to a second bucket brigade
 * into which your modified buckets should be placed.
 * consumed, which must always
 * be declared by reference, should be incremented by the length of the data
 * which your filter reads in and alters. In most cases this means you will
 * increment consumed by $bucket->datalen
 * for each $bucket. If the stream is in the process of closing
 * (and therefore this is the last pass through the filterchain),
 * the closing parameter will be set to true.
 * The filter method must return one of
 * three values upon completion.

 * This method is called during instantiation of the filter class
 * object. If your filter allocates or initializes any other resources

 * When your filter is first instantiated, and
 * yourfilter-&gt;onCreate() is called, a number of properties
