Just noticed this today. The following script: <quote> $a = 2; $b = ceil(3 / 2);
if ($a == $b) { print "\$a and \$b are the same.\n"; } $foo[$a] = '2'; if (isset($foo[$b])) { print "\$foo[\$b] is set.\n"; } unset($foo[$b]); print_r($foo); </quote> Results in this output: <quote> $a and $b are the same. $foo[$b] is set. Array ( [2] => 2 ) </quote> ceil() returns a variable of type double. In the above script I expected $foo to become an empty array after calling unset(). But it seems that unset() will not remove an array element when you refer to its key using a double, although isset() will return true when referenced the same way. If I cast $b to either an int or a string, the unset call works. Am I just missing the portion of the manual that documents this behavior, or is this a bug? Just thought I'd see if anyone had run across this before...TIA -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
