Question

今天我在控制台中测试了一些似乎在服务器端出现问题的脚本，对于某个文件，我得到了以下建议：

糟糕！你的一个进程（php，pid 15278）因资源使用过多而被杀死。有关详细信息，请联系DreamHost支持。

好的，得到它，我应该升级我的托管，但我不清楚为什么有时会发生更明显的资源使用。

处理导致错误的文件的代码段生成了输出：

Iteration 1 Start
Memory Usage At the Start: 31,179.26Kbytes //Got with memory_get_usage
Memory Usage At the End: 26,350.64Kbytes
Duration:14
Iteration 2 Start

Yikes! One of your processes (php, pid 15278) was just killed for excessive resource usage.
Please contact DreamHost Support for details.

但是，使用另一个文件（更大的文件），我得到以下日志：

Iteration 1 Start
Memory Usage At the Start: 132,115.70Kbytes
Memory Usage At the End: 26,350.64Kbytes: 129,268.95Kbytes
Duration:34
Iteration 2 Start
Memory Usage At the Start: 131,368.04Kbytes
Memory Usage At the End: 129,287.41Kbytes
Duration:36
....

依旧......

问题是，为什么我总是得到第一个文件的相同错误，似乎使用更少的内存，而第二个完成其12次迭代而没有一个问题？有什么猜测吗？

更新：已添加代码
