note 77978 added to function.isset

Note that isset is lazy -- the first undefined variable causes it to return. Have a look at this example: <?php class Foo { public function __isset($varname) { echo "ZOMG! isset was called on my $varname!\n"; } } $foo = new Foo; // bar will never get checked var_dump(isset($foo->foo, $foo->bar)); // Output: // ZOMG! isset was called on my foo! // bool(false) ?> ---- Server IP: 217.13.201.10 Probable Submitter: 78.51.103.160 ---- Manual Page -- http://www.php.net/manual/en/function.isset.php Edit -- https://master.php.net/note/edit/77978 Del: integrated -- https://master.php.net/note/delete/77978/integrated Del: useless -- https://master.php.net/note/delete/77978/useless Del: bad code -- https://master.php.net/note/delete/77978/bad+code Del: spam -- https://master.php.net/note/delete/77978/spam Del: non-english -- https://master.php.net/note/delete/77978/non-english Del: in docs -- https://master.php.net/note/delete/77978/in+docs Del: other reasons-- https://master.php.net/note/delete/77978 Reject -- https://master.php.net/note/reject/77978 Search -- https://master.php.net/manage/user-notes.php
