PHP version: 5.3.0
PHP Bug Type: Scripting Engine problem
Bug description: Current directory in shutdown function leaks between requests
Description:
------------
In 5.3.0 one of my scripts stopped working due to the behaviour documented
at the bottom of the register_shutdown_function page.
The actual problem is that if I change the directory in the shutdown
function, that change persists across requests and can end up in completely
unrelated scripts' shutdown function calls.
Reproduce code:
---------------
<?php
echo "Script A\n";
function test() {
echo getcwd() . "\n";
if ( file_exists('file.inc') ) {
include 'file.inc';
}
}
register_shutdown_function('test');
?>
<?php
echo "Script B\n";
function change() {
chdir('/tmp/');
file_put_contents('file.inc', '<?php echo "something nasty\n"; ?>');
}
register_shutdown_function('change');
?>
Expected result:
----------------
Script A
/var/www/localhost/htdocs/
Script B
Script A
/var/www/localhost/htdocs/
Actual result:
--------------
Script A
/var/www/localhost/htdocs/
Script B
Script A
/tmp
something nasty
