如果标题有点困惑，请见谅。

我下面的结果指出了正在发生的事情。

这个问题已经变得非常广泛，所以我在这里强调这两件事:

看我的 更新 在底部，出于合理的原因。

整个文件: (见第 86 行)http://codepad.org/oIXaZZaB

这是发生了什么:

我有这个数组，它包含每个语言代码的计数整数。

最佳答案

我也无法重现您的错误。在我看来，您的脚本被调用了两次(请参阅“全部”中的项目是递增的，但不是“唯一”中的。
file_put_contents()没有问题.您可以通过在脚本中添加以下内容来验证这一点:

<?php

mail('you@domain.tld', 'script executed at '.time(), '');

// your code ...

php yourscript.php

关于php - file_put_contents() 弄乱了更新的数组值，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/20372587/
