CakePHP中的MySQL连接->为什么我不断收到超过30秒的致命错误？

<?php
class PersonalBlogController extends AppController {

    var $name = \'PersonalBlog\';
    var $uses = array(\'PersonalBlog\');

    function index(){
        //ini_set(\'max_execution_time\', 300);
        debug($this->PersonalBlog->findAll());
        //debug($this->PersonalBlog->find(\'all\'));
    }
}?>
