bw_trace_get_attached_hooks() – Return the attached hooks

You appear to be a bot. Output may be restricted

Description

Return the attached hooks

Reduce the $wp_filter[ $tag ] structure to something a little easier to interpret e.g. For the "wp_default_styles" hook it will be

: 0   bw_trace_attached_hooks;1 
: 10   wp_default_styles;1 

Note: We can't use foreach against $wp_filter[ $tag ] since this moves the current pointer to the end of the array and messes up further filter functions. We need to work on a copy. See http://php.net/manual/en/control-structures.foreach.php

Usage

$string = bw_trace_get_attached_hooks( $tag );

Parameters

$tag

( string ) required – the action hook or filter

Returns

string the attached hook information
