Cache.php 不知道哪位写的源代码~

//cache constructor,optional expiring time and cache path
public function Cache($exp_time = 3600,$path = "cache/") {
$this -> cache_expire = $exp_time;
$this -> cache_path = $path;
}

//returns the filename for the cache
private function fileName($key) {
return $this -> cache_path . md5($key);
}

//creates new cache files with the given data,$key== name of the cache,data the info/values to store
public function put($key,$data) {
$values = serialize($data);
$filename = $this -> fileName($key);
$file = fopen($filename,'w');
if ($file) {//able to create the file
fwrite($file,$values);
fclose($file);
} else
return false;
}

//returns cache for the given key
public function get($key) {
$filename = $this -> fileName($key);
if (!file_exists($filename) || !is_readable($filename)) {//can't read the cache
return false;
}
if (time() < (filemtime($filename) + $this -> cache_expire)) {//cache for the key not expired
$file = fopen($filename,"r");
// read data file
if ($file) {//able to open the file
$data = fread($file,filesize($filename));
fclose($file);
return unserialize($data);
//return the values
} else
return false;
} else
return false;
//was expired you need to create new
