.
Thanks a lot

Hi!
The warning is being emitted from the IF statement body, where you're not
actually performing an assignment, but a comparison instead:
$t_aa["bb"]=="cc";

Subject: [PHP-DEV] php short circuit bug?
Hi everybody,
Perhaps am I making a mistake, but the following code fragment:
<?php
$t_aa = array();
if ( !isset($t_aa["bb"]) || ($t_aa["bb"]=="") ) $t_aa["bb"]=="cc";
?>
Emits the following notice:
PHP Notice: Undefined index: bb in test.php on line 4
The php documentation :
http://php.net/manual/en/language.operators.logical.php
http://php.net/manual/en/language.operators.logical.php PHP: Logical
Operators - Manual
php.net
Logical Operators; Example Name Result $a and $b: And: TRUE if both $a and
$b are TRUE. $a or $b: Or: TRUE if either $a or $b is TRUE. $a xor $b: Xor:
TRUE if either ...
states in exemple 1 that short circuit is implemented.
In my example as !isset($t_aa["bb"]) true, then the second expression
($t_aa["bb"]=="")should not be evaluated!
Is it a php bug? Or am i missing something?
Cheers,
