The second argument is a list of characters. I'm surprised this has worked for you up till now. I think most people would use the following to do what you want: <?php echo preg_replace( '#^options\[#', '', $a ) ?> Or they would do test and strip: <?php if( substr( $a, 0, 8 ) === 'options[' ) { echo substr( $a, 8 ); } ?> Or maybe: <?php if( preg_match( '#^options\[#', $a ) ) { echo substr( $a, 8 ); } ?> Cheers, Rob. -- http://www.interjinn.com Application and Templating Framework for PHP
