array ( [0] => http://test.com/server1/image?img=nortel.jpg )  array ( [1] => http://test.com/server1/image?img=network.jpg )

i need replace text inside each url , replace server server1 server5 , word image photo each url should this:

http://test.com/server5/photo?img=

i have tried variation of str_replace functions cannot work:

$simgurl = $aresults[1][0];      $filter_url ='server1/image';        $replace='server5/photo';     $filtered_url = str_replace($filter_url, $replace, $aresults);     print_r($aresults);

what best way accomplish this? thanks

for ($i = 0; $i <= sizeof($aresults); $i++) {     $aresults[$i] = str_replace('server1/image', 'server5/photo', $aresults[$i]); }
