Bug Type: Reproducible crash
Operating System: RHES3
PHP Version: 5CVS-2005-09-09 (snap)
New Comment:
Your function is stuck in a recursive loop, eventually this will seg
fault.
If you wanna see it in action add the following lines to the top of the
function.
static $depth = 0;
echo $depth++;
To fix the problem remove the . "\\" from the tail of
"scandir_recursive($directory.$folderItem."\\");".
Here's a cleaned up function to not display errors and so forth.
function scandir_recursive($directory)
{
$folderContents = array();
$directory = realpath($directory) . DIRECTORY_SEPARATOR;
$folderItems = @scandir($directory);
if (!is_array($folderItems)) return "No access";
foreach ($folderItems as $folderItem) {
if (substr($folderItem, 0, 1) != ".") { // Ignore anything
hidden
if (is_dir($directory . $folderItem .
DIRECTORY_SEPARATOR))
$folderContents[$folderItem] =
scandir_recursive($directory . $folderItem);
else
$folderContents[] = $folderItem;
}
}
return $folderContents;
}

Description:
------------
recursive scandir causes seg fault. code example from
http://us2.php.net/scandir User Contributed Notes.
Reproduce code:
---------------
<?php
$afiles = scandir_recursive("/tmp");
function scandir_recursive($directory)
{
$folderContents = array();
$directory = realpath($directory).DIRECTORY_SEPARATOR;
foreach (scandir($directory) as $folderItem) {
if ($folderItem != "." AND $folderItem != "..") {
if (is_dir($directory.$folderItem.DIRECTORY_SEPARATOR)) {
$folderContents[$folderItem] = scandir_recursive(
$directory.$folderItem."\\");
}
else {
$folderContents[] = $folderItem;
}
}
}
return $folderContents;
}
?>
Expected result:
----------------
nothing as there is not output in the sample. just expected it to run
without a seg fault.
Actual result:
--------------
[EMAIL PROTECTED] design]# date;php sample.php;date
Wed Sep 7 16:11:11 CDT 2005
