note 76160 added to function.strlen

The function "empty" tests whether a variable will evaluate as FALSE; the string '0' (as well as the number 0) does. Another simple way of testing for an empty string is: if($string=='') foo(); else bar(); This will match an empty string and anything that converts to it (such as NULL/unset variable), but not the number zero as either a number or a string. ---- Server IP: 147.32.160.17 Probable Submitter: 86.49.6.75 ---- Manual Page -- http://www.php.net/manual/en/function.strlen.php Edit -- https://master.php.net/note/edit/76160 Del: integrated -- https://master.php.net/note/delete/76160/integrated Del: useless -- https://master.php.net/note/delete/76160/useless Del: bad code -- https://master.php.net/note/delete/76160/bad+code Del: spam -- https://master.php.net/note/delete/76160/spam Del: non-english -- https://master.php.net/note/delete/76160/non-english Del: in docs -- https://master.php.net/note/delete/76160/in+docs Del: other reasons-- https://master.php.net/note/delete/76160 Reject -- https://master.php.net/note/reject/76160 Search -- https://master.php.net/manage/user-notes.php
