php_user_filter::onCreate — Called when creating the filter
This method is called during instantiation of the filter class object. If your filter allocates or initializes any other resources (such as a buffer), this is the place to do it.
When your filter is first instantiated, and yourfilter->onCreate() is called, a number of properties will be available as shown in the table below.
| Property | Contents |
|---|---|
| FilterClass->filtername | A string containing the name the filter was instantiated with. Filters may be registered under multiple names or under wildcards. Use this property to determine which name was used. |
| FilterClass->params |
The contents of the params parameter passed
to stream_filter_append()
or stream_filter_prepend().
|
| FilterClass->stream |
The stream resource being filtered. Maybe available only during
filter() calls when the
closing parameter is set to FALSE.

This function has no parameters.
Your implementation of
this method should return FALSE on failure, or TRUE on success.
