Bug #11524 Updated: shifting or popping array with leading or trailing empty elements

ID: 11524 Updated by: cardinal Reported By: jmroth@iip.lu Old-Status: Open Status: Bogus Bug Type: Arrays related Operating system: PHP Version: 4.0.5 Assigned To: Comments: Please see the man pages for array_shift and array_pop. Both functions return the element they removed, not the modified array. So, $uri = array_shift($uri); is returning an empty string, the first element of the array. Previous Comments: --------------------------------------------------------------------------- [2001-06-17 18:32:12] jmroth@iip.lu Let's say I have this string: /FAQ/ (a URI, actually) An explode action (delim is /)with a resulting count of the array reveals 3 elements. After an array_shift or array_pop, the count goes to 1. 3-1=1? $uri = strtolower(preg_replace("/[^a-zA-Z0-9/]/","",$HTTP_SERVER_VARS["REQUEST_URI"])); $uri = explode("/", $uri); // make it an array echo count($uri); $uri = array_shift($uri); // delete first value which is always empty echo count($uri); --------------------------------------------------------------------------- ATTENTION!
