Note Submitter: admin at french-web-proxy dot fr ---- I Would add a note about varable scope in a function created threw a runetime created function... <?php //for exemple $replace_text='bar'; $foo='foo'; $replace_text=preg_replace_callback('#bar#', create_function('$result',' global $foo; $foo=$result; //set variable to bar //$foo is destroyed here ') ,$replace_text); echo $foo; //print 'foo' and not 'bar' ?> the solution is to use superglobals variables...for example $_SERVER <?php $replace_text='bar'; $_SERVER['foo']='foo'; $replace_text=preg_replace_callback('#bar#', create_function('$result',' //global $_SERVER["foo"]; <--don t need this $_SERVER["foo"]=$result; //set variable to bar ') ,$replace_text); echo $_SERVER['foo']; //print 'foo' and not 'bar' ?> here it is ;)
