appears kwilson at shuttlebox dot net that you may have just made unintended side effect. Note that adding the global $variable to your test function make the closure function echo second rather than first So the anonymous function works as expected with respect to globals. <?php $variable = "first"; $closure = function() { global $variable; echo $variable . "\n"; }; $closure(); function test($closure) { global $variable; //Note the scope added here $variable = "second"; $closure(); } test($closure); ?> prints: first second tested with php 5.3.1 ---- Server IP: 192.41.40.227 Probable Submitter: 67.191.151.222 ---- Manual Page -- http://www.php.net/manual/en/functions.anonymous.php Edit -- https://master.php.net/note/edit/96341 Del: integrated -- https://master.php.net/note/delete/96341/integrated Del: useless -- https://master.php.net/note/delete/96341/useless Del: bad code -- https://master.php.net/note/delete/96341/bad+code Del: spam -- https://master.php.net/note/delete/96341/spam Del: non-english -- https://master.php.net/note/delete/96341/non-english Del: in docs -- https://master.php.net/note/delete/96341/in+docs Del: other reasons-- https://master.php.net/note/delete/96341 Reject -- https://master.php.net/note/reject/96341 Search -- https://master.php.net/manage/user-notes.php
