foreach and references
Apparently this is not a bug and it's documented:
<?php
$array = array('foo', 'bar');
foreach ($array as &$foo);
foreach ($array as $foo);
var_dump($array);
?><?php
array(2) {
[0]=>
string(3) "foo"
[1]=>
&string(3) "foo"
}
?>Remember what http://www.php.net/manual/en/control-structures.foreach.php say about this:
Reference of a $value and the last array element remain even after the foreach loop. It is recommended to destroy it by unset().

Thank you very much for this
Thank you very much for this tutorial. It's been rather helpful. I only wanted to emphasize readers' attention on the thing that when using to pass an array's key ($key => $value), the key must be a string and not binary content - containing 0's, f.e., as was my case when i used foreach to parse bencoded data handed back to me from a bittorrent tracker scraping - as this will throw foreach off and hand you a key that is binary different than the actual content of the array.
