可能重复：
在 php 中已用尽 33554432 字节的允许内存大小（尝试分配 43148176 字节）

执行代码时出现以下错误。

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 32 bytes)

也试过了ini_set('memory_limit', '128M');，但没有奏效。我的 php.ini 文件中的内存限制为 128MB。请帮忙。

我正在添加代码。我是 php 新手，请帮我解决这个问题。

<?php

$connection = imap_open($hostname,$username,$password) or die('Cannot connect to Tiriyo: ' . imap_last_error());
    ini_set('memory_limit', '256M');

我们会尽力的ini_set('memory_limit', '256M');

134217728 字节 = 128 MB

或者重写代码以消耗更少的内存。

128M == 134217728，您看到的数字。

内存限制工作正常。当它说它试图分配 32 个字节时，即失败前最后一次操作请求的数量。

您是否在构建任何大型数组或读取大型文本文件？如果是这样，请记住释放您不再需要的任何内存，或将任务分解为更小的步骤。
