Status: Open
Bug Type: Arrays related
Operating System: Windows XP
PHP Version: 5.1.6
New Comment:
Confirm with 5.1.6:
<?php
$a['b']='foo';
function boo($_params){
$_params['b'] = 'bar';
echo $a['b'];
}
foreach($a as $key => &$val) {} // ?!
echo $a['b'];
boo($a);
echo $a['b'];
?>
If you comment out `foreach` loop or remove & near `$val`, code works
OK. Loop does nothing and $val is *never* mentioned in code elsewhere.

This problem affects all the arrays and not just the $_GET one. Please
note that $value is not reused outside of the foreach loop. Effectively
this renders foreach by reference useless.
Another very simple script which reproduces the problem:
$myarray = array( 'mykey' => 'foo' );
function doit($tmp) { $tmp['mykey'] = 'bar'; }
foreach($myarray as $key => &$value) {}
echo $myarray['mykey']."\n";
doit($myarray);
echo $myarray['mykey']."\n";
and outputs
foo
bar
instead of
foo
foo

Where exactly is this behaviour documented? Can you point to the
documentation page as I failed to find this.
Also, another defect http://bugs.php.net/bug.php?id=29992 which was
referenced here is a different problem. In my case I do not reuse the
reference variable $value .
