WordPress: How do I get all the registered functions for 'the_content' filter

Question

I have a question regarding WordPress, specifically version 3.0 and newer.

Does anyone know how to get an array or list of all the functions that will be applied or

Answer 1

Simple function to print from the filter array?

function print_filters_for( $hook = '' ) {
    global $wp_filter;
    if( empty( $hook ) || !isset( $wp_filter[$hook] ) )
        return;

    print '
';
    print_r( $wp_filter[$hook] );
    print '
';
}

Call it where you need it.

print_filters_for( 'the_content' );
