> So you found sanitize_title (you're good enough at PHP)

Well, I didn't find it by checking the source but during a google research. Someone pointed to the sanitize_title function when it comes to permalink creation.

So I downloaded the WordPress source code and found it in formatting.php.

To be honest I also found the apply_filters function in wp-includes/plugin.php when trying to understand what "sanitize_title" does.

But apply_filters as well as sanitize_title gives me no clue what WordPress does to convert the title. I expected to find some php string manipulation but apply_filters is all greek to me.

function apply_filters($tag, $value) {
    global $wp_filter, $merged_filters, $wp_current_filter;

    $args = array();
    $wp_current_filter[] = $tag;

    // Do 'all' actions first
    if ( isset($wp_filter['all']) ) {
        $args = func_get_args();
        _wp_call_all_hook($args);
    }

    if ( !isset($wp_filter[$tag]) ) {
        array_pop($wp_current_filter);
        return $value;
    }

    // Sort
    if ( !isset( $merged_filters[ $tag ] ) ) {
        ksort($wp_filter[$tag]);
        $merged_filters[ $tag ] = true;
    }

    reset( $wp_filter[ $tag ] );

    if ( empty($args) )
        $args = func_get_args();

    do {
        foreach( (array) current($wp_filter[$tag]) as $the_ )
            if ( !is_null($the_['function']) ){
                $args[1] = $value;
                $value = call_user_func_array($the_['function'], array
+_slice($args, 1, (int) $the_['accepted_args']));
            }

    } while ( next($wp_filter[$tag]) !== false );

    array_pop( $wp_current_filter );

    return $value;
}

My hope and the reason for my posting was, that someone already has written a module/function/... in Perl that accomplished this. It seems this is not the case.
