People using IIS reported serious problems with activeCollab (http://www.activecollab.com/) because
of http://bugs.php.net/bug.php?id=27609.
Installer said that folders are writable and than they received a bunch of write errors when they
tried to upload something.
Solution this two simple functions:
<?php
function folder_is_writable($path) {
if(!is_dir($path)) {
return false;
}
do {
$test_file = $path . '/' . sha1(uniqid(rand(), true));
} while(is_file($test_file));
$put = @file_put_contents($test_file, 'test');
if($put === false) {
return false;
}
@unlink($test_file);
return true;
}
function file_is_writable($path) {
if(!is_file($path)) {
return false;
}
$open = @fopen($path, 'a+');
if($open === false) {
return false;
}
@fclose($open);
return true;
}
?>
