# changing url value with str_replace(), retuns “Array”

 * I am trying to use the str_replace command to replace part of an automatically
   generated URL. The original URL is placed in custom value (‘url’). I need to 
   replace occurrences of “rtex” with “190” in the url itself. The code currently
   reads:
 * <?php $url = get_post_custom_values(“url”);
    echo str_replace(“rtex”, “190”, 
   $url);?>
 * It should be fairly simple, but I am getting a return of:
 * “Array”
 * I’m not terribly experienced with PHP, and any help much appreciated!

 * [get_post_custom_values](http://codex.wordpress.org/Function_Reference/get_post_custom_values)
   returns an array of all values stored against the key – in your case `url`. Even
   if there’s only 1 value, it will still return an array. Try something like:
 * `echo str_replace("rtex", "190", $url[0]);?>`

 * Great, works perfectly. I’m unfamiliar with php and little things like this can
   be tricky to work with. Thanks very much esmi.
