我想创建谁采取一切挨个数0页面的信息10 000 000我不不管它是如何花费的时间履带。 我只是希望它的工作原理。 下面是我得到的错误 

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

该生产线25 

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

还有就是我的完整剧本。

谢谢您的帮助 ！

Answer 1:

假设你使用了XDebug，您可以设置自己的极限与

ini_set('xdebug.max_nesting_level', $limit)


Answer 2:

/etc/mysql/my.cnf参数文件更改为类似的东西max_allowed_pa​​cket个= 512M

获得确保你有Xdebug的安装（用phpinfo（）），然后更改文件/etc/php5/fpm/php.ini添加或编辑的行：xdebug.max_nesting_level = 1000

重新启动这两个服务sudo的服务mysql的重启sudo的服务PHP5-FPM重启

如果不工作，你仍然可以设置这些两个参数为假，在/etc/php5/fpm/php.ini xdebug.remote_autostart = 0 xdebug.remote_enable = 0



Answer 3:

对我来说，这是关系到作曲家。 有些厂商在composer.json文件进行了更新，但我忘了运行的命令作曲家更新也不作曲家安装 。 系统生成errros的级联，这是造成这种“最大嵌套级别”。

执行这些命令之后，问题是固定



Answer 4:

假设你没有做一个下拉死机错误，只是改变了XDebug的限制。

我通过改变xdebug.ini文件sloved这个问题。 （在我的Mac上，路径是/usr/local/php5-5.6.17-20160108-103504/php.d/50-extension-xdebug.ini，也许你会有点不同。）

在xdebug.ini文件的底部添加新行：

xdebug.max_nesting_level = 500

记住： 你必须改变与您使用的是PHP的xdebug.ini。 例如，如果你在你的电脑安装PHP5和XAMPP，你需要找出你使用的PHP。
