我想为cakephp 2.5.3实现一个高速缓存功能,与find查询相关,但是我想使所有与表相关的事件(update,delete,...)无效。 我把它编入AppModel.php,你能告诉我你对代码逻辑和效率有什么看法吗? 谢谢。CakePHP查询的高速缓存
public function find($conditions = null, $fields = array(), $order = null, $recursive = null) {
$keyName = sha1(serialize(func_get_args()));
if (Cache::read($this->table . '_' . $keyName, '5m') !== false) {
$this->log('read cache ' . $this->table . '_' . $keyName);
return Cache::read($this->table . '_' . $keyName, '5m');
} else {
$data = parent::find($conditions, $fields, $order, $recursive);
Cache::write($this->table . '_' . $keyName, $data, '5m');
$this->addToCacheList($keyName);
$this->log('add ' . $this->table . '_' . $keyName);
return $data;
}
}
public function afterSave($created, $options = array()) {
$this->flushCacheList();
parent::afterSave($created, $options);
}
public function afterDelete() {
$this->flushCacheList();
parent::afterDelete();
}
public function addToCacheList($keyName) {
if (Cache::read($this->table, '5m') !== false) {
$values = Cache::read($this->table, '5m');
$values[] = $keyName;
} else {
$values = array($keyName);
}
Cache::write($this->table, $values, '5m');
}
public function flushCacheList() {
if (Cache::read($this->table, '5m')) {
$values = Cache::read($this->table, '5m');
foreach($values AS $value) {
Cache::delete($this->table . '_' . $value, '5m');
$this->log('flush ' . $this->table . '_' . $value);
}
Cache::delete($this->table, '5m');
}
}
