php_user_filter::onCreate — Called when creating the filter

说明

public php_user_filter::onCreate(): bool

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`.

参数

此函数没有参数。

返回值

Your implementation of this method should return false on failure, or true on success.
