Note that this (and probably other is_* functions) behave differently with respect to lazy evaluation: php > $v = ''; php > echo $v[0]; PHP Notice: Uninitialized string offset: 0 in php shell code on line 1 # As expected! php > empty($v) && $v[0]; # As expected, this does not throw a notice, since $v[0] is never evaluated. # However: php > is_string($v) && $v[0]; PHP Notice: Uninitialized string offset: 0 in php shell code on line 1 ---- Server IP: 83.137.20.135 Probable Submitter: 83.87.145.112 ---- Manual Page -- http://www.php.net/manual/en/function.is-string.php Edit -- https://master.php.net/note/edit/110395 Del: integrated -- https://master.php.net/note/delete/110395/integrated Del: useless -- https://master.php.net/note/delete/110395/useless Del: bad code -- https://master.php.net/note/delete/110395/bad+code Del: spam -- https://master.php.net/note/delete/110395/spam Del: non-english -- https://master.php.net/note/delete/110395/non-english Del: in docs -- https://master.php.net/note/delete/110395/in+docs Del: other reasons-- https://master.php.net/note/delete/110395 Reject -- https://master.php.net/note/reject/110395 Search -- https://master.php.net/manage/user-notes.php
