#31114 [Asn]: foreach modify array

ID: 31114 Updated by: derick@php.net Reported By: clemens at gutweiler dot net Status: Assigned Bug Type: Arrays related Operating System: Linux 2.4.27 PHP Version: 4.3.10 Assigned To: derick New Comment: scoop, your problem is because you need to upgrade your Zend extensions. Your example works fine for me. Previous Comments: ------------------------------------------------------------------------ [2004-12-16 18:55:50] scoop at freshmeat dot net There definitely is a problem for cases using the syntax $array = array('foo','bar','baz'); foreach($array as $value) { var_dump($value); } .. in which case $value will be output as an array: array(2) { [0]=> string(3) "foo" [1]=> int(0) } .. which obviously breaks a few code snippets. ------------------------------------------------------------------------ [2004-12-16 13:07:17] derick@php.net (The only bug here is that it doesn't give a warning, using $k for both key and value is not supposed to work!) ------------------------------------------------------------------------ [2004-12-16 11:41:54] derick@php.net I don't think this was ever supposed to work. ------------------------------------------------------------------------ [2004-12-16 11:14:47] mc at tyumen dot ru Cangelog: "Backported Marcus' foreach() speedup patch from PHP 5.x." How I can remove this patch ? For example doesn't work Smarty. ------------------------------------------------------------------------ [2004-12-16 10:44:05] clemens at gutweiler dot net Description: ------------ foreach modifies an array, if key and value are the same variable. see reproduction code. Reproduce code: --------------- <?php $foo = array( 'foo' => 'bar', 'dings' => 'dongs' ); foreach( $foo as $k => $k ) {} var_dump( $foo ); ?> array(2) { ["foo"]=> string(5) "dings" ["dings"]=> NULL } Expected result: ---------------- array(2) { ["foo"]=> string(3) "bar" ["dings"]=> string(5) "dongs" } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=31114&edit=1
