#29668 [Opn->Bgs]: Memory leak when looping an associative array

ID: 29668 Updated by: iliaa@php.net Reported By: thecanadiancrappler at hotmail dot com -Status: Open +Status: Bogus Bug Type: Reproducible crash Operating System: Windows XP SP 1 PHP Version: 4.3.8 New Comment: 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 Each time you do $array[$i] you add a new value to the array. The loop goes on forever since each time the size of the array being calculated, move count($array) outside the loop.

Windows grinds to a halt as 1gb of Virtual Memory is gobbled up. Trying to echo each element of the array returns nothing as would be expected, but concatting or executing a function such a stripslashes on the elements causes the memory leak. My php.ini differs only in max_execution time and the maximum size of POST uploads. Reproduce code: --------------- $array['a'] = 'Some text'; $array['b'] = "It\'s nice text"; // prints 2 echo count($array); // prints nothing echo $array[0]; // does nothing $array[0] = stripslashes($array[0]); for ($i=0; $i<count($array); $i++) { // does nothing echo $array[$i]; // memory leak $array[$i] = 'blah' . $array[$i]; // memory leak $array[$i] = stripslashes($array[$i]); } Expected result: ---------------- To have no effect on the array Actual result: -------------- Sorry, I can't decipher your instructions for using backtrace! Shoot the stupid guy ;o) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=29668&edit=1
