Smarty

a function that removes old unused cached files would be great. (fileatime())

Here you go (untested):

[php:1:3b061d02e4]Smarty_GC extends Smarty {
var $_gc_ratio = 50; // probability ratio
var $_gc_exp = 3600; // cache expire time

function Smarty_GC() {
$this->Smarty();
if(rand(1,$this->_gc_ratio) == 1)
$this->clear_all_cache($this->_gc_exp);
}
}

$smarty = new Smarty_GC;
...[/php:1:3b061d02e4]

If you want something that works with fileatime(), then make a custom function for it. Here's a quick and dirty method using find (linux/unix):

[php:1:eeb8573cf0]Smarty_GC extends Smarty {
var $_gc_ratio = 50; // probability ratio
var $_gc_exp = 2; // cache access time in days

function Smarty_GC() {
$this->Smarty();
if(rand(1,$this->_gc_ratio) == 1)
$this->garbage_collect();
}

function garbage_collect() {
$_cache_dir = $this->cache_dir;
$_atime = $this->_gc_exp;
`/usr/bin/find $_cache_dir/. -atime +$_atime -exec rm -rf {} \;`;
}
}[/php:1:eeb8573cf0]

thx

but its an win-system. maybe i can alter the clear_cache funktion.

You'll have to write a method that uses the PHP file functions to traverse the cache directory and unlink the files that are stale. Overriding the Smarty clear_cache function is up to you.

im just working on it, but my problem is, that i dont have experiance with oop. but im trying

during my exploration, i have an question in the file core.rmdir.php. there is this code:

Just use the above example and replace the guts of the garbage_collect() function with your own removal logic. You have access to the Smarty properties with $this, such as $this->cache_dir.
