little url helper addition - fix_slashes()

[eluser]ntheorist[/eluser]
thought i'd toss out this little function i added to the url helper. I run into problems sometimes when creating urls dynamically, in which concatenated urls end up with multiple slashes '//'. Hard sometimes to track where the slashes are so this function seems to help.

Optionally you can force prep_url, or if the url is already prepped it will re-prep it, to ensure the double slashes in http:// aren't replaced.

Code:

if ( ! function_exists('fix_slashes') )
{
    function fix_slashes($str = NULL, $prep = FALSE)
    {
        if($str)
        {
            if (substr($str, 0, 7) == 'http://' || substr($str, 0, 8) == 'https://')
            {
                $prep = TRUE;
            }
            
            $str = str_replace('https://','',$str);
            $str = str_replace('http://','',$str);
            $str = preg_replace('|(/)+|','/',$str);
            
            if($prep === TRUE)
            {
                $str = prep_url($str);
            }
            
            return $str;
        
        }
        
        return '';
    }
}

usage:

$url = 'controller//function/var1//var2/';

fix_slashes($url); // controller/function/var1/var2/
fix_slashes($url, TRUE); // http://controller/function/var1/var2/
        
$url = 'http://mysite.com//controller/function/var1///var2//';
fix_slashes($url); // http://mysite.com/controller/function/var1/var2/
