note 111081 added to function.preg-replace-callback

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 ;) ---- Server IP: 69.147.83.199 Probable Submitter: 87.88.65.39 ---- Manual Page -- http://php.net/manual/en/function.preg-replace-callback.php Edit -- https://master.php.net/note/edit/111081 Del: integrated -- https://master.php.net/note/delete/111081/integrated Del: useless -- https://master.php.net/note/delete/111081/useless Del: bad code -- https://master.php.net/note/delete/111081/bad+code Del: spam -- https://master.php.net/note/delete/111081/spam Del: non-english -- https://master.php.net/note/delete/111081/non-english Del: in docs -- https://master.php.net/note/delete/111081/in+docs Del: other reasons-- https://master.php.net/note/delete/111081 Reject -- https://master.php.net/note/reject/111081 Search -- https://master.php.net/manage/user-notes.php
