我想创建一个爬虫,从0到10 000 000逐个获取所有页面的信息.我不需要花多少时间.我只是希望它有效.这是我获得的错误

Fatal error: Maximum function nesting level of '100' reached, aborting! in D:\wamp\www\crawler\index.php on line 25

第25行是

$htmlstr = (string)$this->curlGet($url);

还有我完整的脚本.

谢谢您的帮助 !

header('Content-Type: text/html; charset=utf-8'); 
ini_set('max_input_nesting_level','100000');
ini_set('max_execution_time','100000'); 

class crawler{

    private $url;
    private $page;
    private $bothurl;
    private $innerDom = null;
    public $prop;
    public $entry;

    function __construct($entry){
        $this->entry = $entry;
        $this->bothurl = array('http://www.remax-quebec.com/fr/inscription/Q/'.$entry.'.rmx','http://www.remax-quebec.com/en/inscription/Q/'.$entry.'.rmx');
        $this->scan();
    }

    private function scan(){
        $i =0;
        foreach($this->bothurl as $url){
            $this->url = $url;
            $this->lang = ($i==0)?'fr':'en';
            $htmlstr = (string)$this->curlGet($url);
            $dom = new DOMDocument;
            @$dom->loadHTML($htmlstr);
            $this->page = …

我正在与由Doctrine管理的实体合作开发Symfony项目.以下是我的实体的代码:

class User {
    /**
     * @ORM\OneToMany(targetEntity="Appointment", mappedBy="user")
     */
    private $appointments;

    /**
     * Get appointments
     *
     * @return \Doctrine\Common\Collections\ArrayCollection
     */
    public function getAppointments()
    {
        return $this->appointments;
    }

    /**
     * Get appointments at a specified date
     *
     * @param \DateTime $date
     * @return \Doctrine\Common\Collections\Collection|static
     */
    public function getAppointmentsAtDate(\DateTime $date) {
        $allAppointments = $this->getAppointments();

        $criteria = Criteria::create()->where(/* some clever filtering logic goes here */);

        return $allAppointments ->matching($criteria);
    }
}

getAppointments是由Doctrine自动生成的.该getAppointmentsAtDate方法由我自己实施.该方法的PHPDoc标头由PhpStorm自动生成.

我无法理解的是static我的自定义方法的返回类型中的关键字.

根据我对PHPDoc类型的 理解,static表示此方法返回调用它的类的实例,在本例中为User …
