note 58274 added to function.settype

note that settype() will initialize an undefined variable. Therefore, if you want to preserve type and value, you should wrap the settype() call in a call to isset(). <?php settype($foo, "integer"); echo("|$foo|"); ?> prints "|0|", NOT "||". To get the latter, use: <?php if(isset($foo)) settype($foo, "integer"); echo("|$foo|"); ?> ---- Manual Page -- http://www.php.net/manual/en/function.settype.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+58274 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+58274&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+58274&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+58274&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+58274&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+58274&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+58274&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+58274&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+58274&report=yes Search -- http://master.php.net/manage/user-notes.php
