note 52923 added to function.trim

Note that manithu's post on 29-Mar-2005 02:49 for identifying strings that only contain whitespaces will also identify strings like "0" and " 0 " as being empty. If you want to check whether something ONLY has whitespaces, use the following: <?php if (trim($foobar)=='') { echo 'The string $foobar only contains whitespace!'; } ?> ---- Manual Page -- http://www.php.net/manual/en/function.trim.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+52923 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+52923&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+52923&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+52923&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+52923&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+52923&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+52923&report=yes Search -- http://master.php.net/manage/user-notes.php
