判断一个字符串是否属于序列化后的数据

function is_serialized( $data ) {
     $data = trim( $data );
     if ( 'N;' == $data )
         return true;
     if ( !preg_match( '/^([adObis]):/', $data, $badions ) )
         return false;
     switch ( $badions[1] ) {
         case 'a' :
         case 'O' :
         case 's' :
             if ( preg_match( "/^{$badions[1]}:[0-9]+:.*[;}]\$/s", $data ) )
                 return true;
             break;
         case 'b' :
         case 'i' :
         case 'd' :
             if ( preg_match( "/^{$badions[1]}:[0-9.E-]+;\$/", $data ) )
                 return true;
             break;
     }
     return false;
