note 85854 added to function.function-exists

to php at fluidthoughts dot com you aren't comparing against false, that if compares against true, so it's going to return that, as false != true true being 1, True, (bool)True, etc. false being 0, False, Null, etc <?php $foo=null; if ($foo) { echo 'yay'; } //does not echo yay, because null is not True $foo=false; if ($foo) { echo 'yay'; } //does not echo yay, because false is not True $foo=null; if (!$foo) { echo 'yay'; } //echoes yay! $foo=false; if (!$foo) { echo 'yay'; } //echoes yay! ?> This.. <?php if (!function_exists('')) { echo "empty string function doesnt exist as compared as negative\n"; } if (!function_exists(NULL)) { echo "NULL function doesnt exist as compared as negative\n"; } ?> Works. Alternatively, to enter upon existance.. Use your code. Since they dont exist, it wont enter.. ---- Server IP: 209.41.74.194 Probable Submitter: 24.30.66.76 ---- Manual Page -- http://www.php.net/manual/en/function.function-exists.php Edit -- https://master.php.net/note/edit/85854 Del: integrated -- https://master.php.net/note/delete/85854/integrated Del: useless -- https://master.php.net/note/delete/85854/useless Del: bad code -- https://master.php.net/note/delete/85854/bad+code Del: spam -- https://master.php.net/note/delete/85854/spam Del: non-english -- https://master.php.net/note/delete/85854/non-english Del: in docs -- https://master.php.net/note/delete/85854/in+docs Del: other reasons-- https://master.php.net/note/delete/85854 Reject -- https://master.php.net/note/reject/85854 Search -- https://master.php.net/manage/user-notes.php
