Make this a documentation problem..I couldn't find this explanation there. :) Previous Comments: ------------------------------------------------------------------------ [2003-06-11 02:59:27] [EMAIL PROTECTED] 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. ------------------------------------------------------------------------ [2003-06-10 18:15:29] [EMAIL PROTECTED] 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> ------------------------------------------------------------------------ [2003-06-10 17:56:08] [EMAIL PROTECTED] Zeev, here is first one I verified with both 4.3.3-dev and 5.0.0-dev. Have fun fixing this one. :) ------------------------------------------------------------------------ [2003-06-10 17:32:00] young at sl dot com dot ua 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 4 9 16 16 ------------------------------------------------------------------------ [2003-06-10 17:24:46] [EMAIL PROTECTED] Not enough information was provided for us to be able to handle this bug.
