Thank you for your interest in PHP.

Sample code to make this bug:
<?php
$arr = array(1, 2, 3, 4, 5);
$sizeOf = sizeof($arr);
for ($i = 0; $i < $sizeOf; $i++) {
	$row =& $arr[$i];
	$row = $row * $row;
}
foreach ($arr as $row) {
echo $row."<br>";
}
?>
Return
1

Zeev, here is first one I verified with both 4.3.3-dev and 5.0.0-dev. Have fun fixing this one. :)

Yes; more evidence:

<?php

$arr = array(1, 2, 3, 4, 5);
$sizeOf = sizeof($arr);

for ($i = 0; $i < $sizeOf; $i++) {
  $row = &$arr[$i];
}

foreach ($arr as $row) {
  echo $row."<br>";
}
?>

Output: 1<br>2<br>3<br>4<br>4<br>

<?php

$arr = array(1, 2, 3, 4, 5);
$sizeOf = sizeof($arr);

for ($i = 0; $i < $sizeOf; $i++) {
  $row = &$arr[$i];
}

foreach ($arr as $x) {
  echo $x."<br>";
}
?>

Output: 1<br>2<br>3<br>4<br>5<br>

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Taking the reproducible example:

<?php
$arr = array(1, 2, 3, 4, 5);
$sizeOf = sizeof($arr);
for ($i = 0; $i < $sizeOf; $i++) {
	$row =& $arr[$i];
	$row = $row * $row;
}
foreach ($arr as $row) {
echo $row."<br>";
}
?>

You shouldn't be using the reference variable that you used previously in the foreach loop, since every iteration will assign the value to both $row, and any other references it's attached to, in this case, $arr[4].  This is why you get the last iterated value ($arr[3]) in $arr[4], when you get to it.

Make this a documentation problem..I couldn't find this explanation there. :)

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.

Note: "If you assign a value to variable with references in the foreach statement, references are modified too." + example:

<?php
$ref = 0;
$row =& $ref;
foreach (array(1, 2, 3) as $row) {
    // do something
}
echo $ref; // 3 - last element of the iterated array
?>
