在Crontab中运行php脚本时，无法实现循环。

Question

我有一个php脚本作为crontab作业运行。

当我在浏览器中运行该文件时，循环完美地执行，但当在crontab中运行时，只执行第一次迭代，没有输出错误。

有什么原因吗？我彻底傻眼了！！！。

crontab条目：usrbinphp homeXXXpublic_htmldirectorycroncron.php 2>&1>> homeXXXpublic_htmldirectorycronscript_output.log usrbincurl -u uname:password --silent --compressed

Answer 1

在循环中使用 "require "而不是 "require_once "会导致一个致命的错误，当再次打到require时，会在下一次迭代中终止。

"Fatal error: 无法重新声明xyz"。但这是在不知道那些 "require "位包含的情况下的猜测。为了避免你因挫折而发疯，第1步是确保你得到所有的日志输出。

在第1行插上一个快速的，当完成调试后删除，或者说，当完成后将display_errors设置为0。
