Bug description:Problem with passing array elements as references in foreach
Description:
------------
I created an array of strings that would be typecast to integers, and cast
them using a foreach loop, passing each element by reference. After
dumping the resulting array, it gave (somewhat) expected results, though
after dumping each element individually, it gave an unexpected result on
the last element.
This happened with PHP 5.3.5 on Mac OS X Snow Leopard, but did not happen
on a Debian system with PHP 5.2.6.
Test script:
---------------
<?php
$array = array('1', '2', '5324', '435', '51');
foreach($array as &$element){
$element = (int)$element;
}
var_dump($array);
foreach($array as $key => $element){
var_dump($key);
var_dump($element);
echo "\n";
}
?>
Expected result:
----------------
array(6) {
[0]=>
int(1)
[1]=>
int(2)
[2]=>
int(3)
[3]=>
int(5324)
[4]=>
int(435)
[5]=>
int(51)
}
int(0)
int(1)
int(1)
int(2)
int(2)
int(3)
int(3)
int(5324)
int(4)
int(435)
int(5)
int(51)
Actual result:
--------------
array(6) {
[0]=>
int(1)
[1]=>
int(2)
[2]=>
int(3)
[3]=>
int(5324)
[4]=>
int(435)
[5]=>
&int(51)
}
int(0)
int(1)
int(1)
int(2)
int(2)
int(3)
int(3)
int(5324)
int(4)
int(435)
int(5)
int(435)
