note 78176 added to function.assert

Note that func_get_args() should be used carefully and never in a string! For example: <?php function asserted_normal($a, $b) { assert(var_dump(func_get_args())); } function asserted_string($a, $b) { assert('var_dump(func_get_args())'); } ?> <?php asserted_normal(1,2) ?> prints array(2) { [0]=> int(1) [1]=> int(2) } but <?php asserted_string(3,4) ?> prints array(1) { [0]=> string(25) "var_dump(func_get_args())" } This is because of that the string passed to assert() is being evaled inside assert, and not your function. Also, note that this works correctly, because of the eval scope: <?php function asserted_evaled_string($a, $b) { assert(eval('var_dump(func_get_args())')); } asserted_evaled_string(5,6); ?> array(2) { [0]=> int(5) [1]=> int(6) } (oh, and for simplicity's sake the evaled code doesn't return true, so don't worry that it fails assertion...) ---- Server IP: 82.160.94.10 Probable Submitter: 83.15.56.98 ---- Manual Page -- http://www.php.net/manual/en/function.assert.php Edit -- https://master.php.net/note/edit/78176 Del: integrated -- https://master.php.net/note/delete/78176/integrated Del: useless -- https://master.php.net/note/delete/78176/useless Del: bad code -- https://master.php.net/note/delete/78176/bad+code Del: spam -- https://master.php.net/note/delete/78176/spam Del: non-english -- https://master.php.net/note/delete/78176/non-english Del: in docs -- https://master.php.net/note/delete/78176/in+docs Del: other reasons-- https://master.php.net/note/delete/78176 Reject -- https://master.php.net/note/reject/78176 Search -- https://master.php.net/manage/user-notes.php
