PHP内存使用情况和限制，同时存储多个变量

Question

一旦从curl_multi_init会话中收到许多变量，我将立即定义/存储它们：

$response_[$deger] = curl_multi_getcontent($ch_[$deger]);

$deger从0循环到200时。$ deger达到〜80时，它将停止存储响应（例如，从$response_[81]开始）。

PS：每次迭代都会从Web服务获取一个小的xml（3-4 KB）。

我认为这是php的内存问题。我该如何解决这个问题？

非常感谢，

关于@Anton的建议，这是我的完整代码：

<?php

ini_set('memory_limit', '4096M'); // after facing problem I put this line to test

$yazi="12345"; // in my entire code $yazi is received as a post parameter.
