如果域不是本地主机,我将如何在 opencart 中只写入/获取缓存?
负责缓存的类是;
class Cache {
private $expire = 3600;
public function __construct() {
$files = glob(DIR_CACHE . 'cache.*');
if ($files) {
foreach ($files as $file) {
$time = substr(strrchr($file, '.'), 1);
if ($time < time()) {
if (file_exists($file)) {
unlink($file);
}
}
}
}
}
public function get($key) {
$files = glob(DIR_CACHE . 'cache.' . preg_replace('/[^A-Z0-9\._-]/i', '', $key) . '.*');
if ($files) {
$cache = file_get_contents($files[0]);
return unserialize($cache);
}
}
public function set($key, $value) {
$this->delete($key);
$file = DIR_CACHE . 'cache.' . preg_replace('/[^A-Z0-9\._-]/i', '', $key) . '.' . (time() + $this->expire);
$handle = fopen($file, 'w');
fwrite($handle, serialize($value));
fclose($handle);
}
public function delete($key) {
$files = glob(DIR_CACHE . 'cache.' . preg_replace('/[^A-Z0-9\._-]/i', '', $key) . '.*');
if ($files) {
foreach ($files as $file) {
if (file_exists($file)) {
unlink($file);
}
}
}
}
}
