为什么这个php脚本在执行过程中会重复？

我自己有一个简单的学习网站，可以解析其他网站的源代码。问题是，有时在通过file\u get\u内容读取源代码时会出现错误。这很好，但是php脚本会在发生此错误后重新启动。因此，发生的错误越多，创建和执行的并发线程就越多

php脚本如下所示：

脚本的另一个输出运行了39分钟，如何运行？：pastebin.com/AnNJMvfL

如您所见，脚本的多个实例似乎同时运行，我不知道为什么会发生这种情况。这也运行在免费的托管服务器上

在一个论坛上还发现ftp客户端有时会错误地覆盖文件，所以我创建了新的文件源，但没有更改日志

如果有人能帮助我，或者至少提出一些可能出错的建议，那就太棒了

再次感谢你

编辑：我在另一台服务器上试用过，它的工作原理与预期的一样。那会是什么呢？什么样的设置会导致这种重复？

leadboard\u parser.php包含什么内容？很抱歉，我忘了包含它：如果读取包含文件\u get\u内容的源代码时出现问题，您将永远无法退出while循环。您尝试过任何调试吗？请看一看。@hd是的，但正如您从输出中看到的，它最终总是设法下载源代码并对其进行解析，以便退出循环并正确完成脚本。此外，我还尝试对错误进行限制，使其打破循环，例如，它达到5个错误，但这无助于脚本自身的重复。
