以文件形式缓存php变量的方法

本文实例讲述了以文件形式缓存php变量的方法。分享给大家供大家参考。具体实现方法如下：

'./cache/',
 //缓存时间
 'cacheTime'=>1,
 //cache 类型 1串化数据 2变量
 'cacheType'=>2,
 //扩展名
 'cacheExe'=>'.php'
 //转换中间变量
 );
 public $return_name=array();
 function __construct($cache_set = array())
 {
  if(!empty($cache_set)) $this->config=array_merge($this->config,$cache_set);
  $this->config['ClassName'] = __CLASS__;
 }
 public function clear($filename=''){
  if (file_exists($this->cache_file($filename))) {
   @unlink($this->cache_file($filename));
  }elseif (empty($filename)){
   $this->clear_dir($this->config['cacheRoot']);
  }else{
   $this->clear_dir($this->config['cacheRoot'].$filename);
   echo $this->config['cacheRoot'].$filename;
  }
 }
 //循环删除路径
 private function clear_dir($dir,$to = false)
 {
  if ($list = glob($dir.'
   $cache_Content = unserialize($cache_Content);
   return $cache_Content;
  }else{
   include_once($file);
   return $var;
  }
 }
 //循环创建目录
 private function makeDir( $dir, $mode = 0777 ) {
  if( ! $dir ) return 0;
  $dir = str_replace( "\\", "/", $dir );
  $mdir = "";
  foreach( explode( "/", $dir ) as $val ) {
   $mdir .= $val."/";
   if( $val == ".." || $val == "." || trim( $val ) == "" ) continue;
   if( ! file_exists( $mdir ) ) {
    if(!@mkdir( $mdir, $mode )){
     return false;
    }
   }
  }
  return true;
 }
}
?>
