我的代码中的'for'循环重复执行第一次遍历代码,然后再转到下一遍。循环应重复3次,但脚本在第一次重复时执行多次。当我在错误日志中看到以下内容时,我意识到了这一点:

我让它在每个循环结束时将循环计数写入日志,你可以看到第一个重复多次。这是与我的循环相关的代码:
for ($count = 0; $count < 4; $count++) {
// Do STUFF HERE
// ERROR_LOG when a successful message has been sent
error_log($count);
sleep(5);
}
我不知道为什么会这样,因为代码对我来说没问题。这可能是服务器问题吗?或者其余代码中的某些东西会影响循环?如何让它循环正确的次数?
如果它可以使用,这是我正在使用的完整代码。它基本上只是将电子邮件附件转发到SQL数据库中的一组电子邮件地址。

答案 0 :(得分:1)
你有问题:
if($emails) { $count = 1;//<======
$count
用于for
循环,但已在内部人员if
中进行了编辑!
所以你必须使用另一个变量名。
