note 82942 added to function.empty

David from CodeXplorer: >> The ONLY reason to use empty() is for code readability. It is the same as an IF/ELSE check. >> So, don't bother using EMPTY in the real world. This is NOT true. empty() will not generate warnings if you're testing against an undefined variable as a simple boolean check will. On production systems, warnings are usually shut off, but they are often active on development systems. You could test a flag with <?php if ($flagvar) ... ?> but this can generate a warning if $flagvar is not set. Instead of <?php if (isset($flagvar) && $flagvar) ... ?> you can simply use <?php if (!empty($flagvar)) ... ?> for easy readability without warnings. ---- Server IP: 208.69.120.35 Probable Submitter: 72.64.121.121 ---- Manual Page -- http://www.php.net/manual/en/function.empty.php Edit -- https://master.php.net/note/edit/82942 Del: integrated -- https://master.php.net/note/delete/82942/integrated Del: useless -- https://master.php.net/note/delete/82942/useless Del: bad code -- https://master.php.net/note/delete/82942/bad+code Del: spam -- https://master.php.net/note/delete/82942/spam Del: non-english -- https://master.php.net/note/delete/82942/non-english Del: in docs -- https://master.php.net/note/delete/82942/in+docs Del: other reasons-- https://master.php.net/note/delete/82942 Reject -- https://master.php.net/note/reject/82942 Search -- https://master.php.net/manage/user-notes.php
