具有运行4个机器人同时, 每个机器人是在新标签打开,一般不会是一个履带脚本一段时间后,执行停止刮花所需的变种。
2 /从db获取URL目标。
3使用CURL或file_get_content获取内容。
4 /用simple_html_dom设置“$ html”。
5 /包含一个“引擎”,用于擦除和操纵内容。
6 /最后 - 检查它是否正确并优化内容并将其存储在db中。 X链接将刷新页面并继续爬网过程之后。
PHP脚本没有错误报告
每件事都像魔术一样工作!但最近几分钟后(不是同一时间)所有的机器人
停止(没有错误闪现)有时只有3人...
有一个脚本,设置每隔Y分钟刷新页面的时间间隔。这是我的
机器人工作,如果他们卡住,但它不是一个答案这个问题。
我检查了apache错误日志,并没有指出任何奇怪的东西。
你有什么想法?

编辑:
经过不断的测试和记录方法(以下插孔咨询)我什么也没找到! 当机器人停止这种情况发生的唯一事情是在Apache日志:

什么烂摊子。请正确缩进您的代码。 – OptimusCrime
这是很多代码,你期望人们通过给你一个答案。您应该先尝试自己调试它,看看您是否可以缩小问题出现的位置。 –
哈哈现在收缩吧 – shlomix
