Question

我在hostgator Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 64 bytes)上收到此错误，但它在bluehost上工作正常我有权访问php.ini，内存限制已经设置为64 memory_limit = 64M;

我无法弄清楚是这样的，请帮助。

我不知道哪部分代码会产生错误，但我提供了所有错误。

的config.php

    <?php
    $currency = '$'; //Currency sumbol or code

    $db_username = 'root';
    $db_password = '';
    $db_name = 'educators';
    $db_host = 'localhost';
    $mysqli = new mysqli($db_host, $db_username, $db_password,$db_name);
    ?>

Answer 1

联系hostgator支持以验证这一点，但在某些情况下，他们会为您修改php.ini或某些托管公司允许您将php.ini放在备用位置，您可以从那里设置选项。

Answer 2

这篇文章太旧了，但对于使用 CentOS 具有 VPS 的某些人可能有用。我遇到了这个问题。

1。打开php.ini

CentOS:
$ nano /etc/php.ini

2。然后找到memory_limit，然后按照以下步骤将其更改为512M

CentOS:
File: /etc/php.ini
memory_limit = 512M;

如果您使用的是multiPHP，则应将相关的php.ini更改为代码使用的版本。
