安装 php7.2-mcrypt 的问题 [英] Issue in installing php7.2-mcrypt

问题描述

因为我正在尝试从 PHP 7.2.X 版本加载 mcrypt 扩展模块.
所以我尝试使用与我的 PHP 的当前版本兼容的 PECL 库，以便安装并点击此链接:在安装过程中在 PHP 7.2 上安装 mcrypt！

以下是在终端执行某些命令后得到的结果.

当我收到这种类型的错误 pecl7.2-sp: command not found

从文档部分，已经明确指出它已被弃用，从安全角度来看将不再可用——从那时起，从 PHP 7.2.X 的发布版本开始.

但是一些项目需要这些依赖项，以便在必要时执行所需的功能.我需要如何解决上述问题?

<小时>

更新:

TL;DR:

我对已发布的答案的投票做出了很多回应.需要根据操作系统架构级别对答案进行分类.由于我使用共享服务器进行托管，因此有多个项目驻留在它上面&用 PHP 5.X.X 版本编码，所以我决定降级到 PHP 7.1.X在我的基于 Debian 的操作系统中默认支持 mcrypt 扩展.

正如我在链接中已经提到的，在 PHP 7.2 上安装 mcrypt 扩展，由 Server Pilot 社区提供.这些人告诉过一个新版本的 pecl-7.2 可以在 PHP-7.2 上安装 mcrypt.不幸的是，它以pecl7.2-sp: command not found 来自已执行的命令.后来网站页面更新了，所以那里的命令与执行时尝试的命令不匹配.

最后，无论哪种解决方案都适合您的操作系统架构级别，就去做吧！

或

如果以下方法无法解决根本原因.
或者，您可以选择默认支持 mcrypt 扩展的 PHP 7.1.X 版本

解决方案

我按照以下步骤安装 mcrypt 用于 PHP7.2，使用 PECL.

1. 安装 PECL

<块引用>

apt-get 安装 php-pecl

2. 在安装 MCRYPT 之前，您必须安装 libmcrypt

<块引用>

apt-get install libmcrypt-dev libreadline-dev

3. 使用 PECL 安装MCRYPT 1.0.1

<块引用>

pecl 安装 mcrypt-1.0.1

4. 安装成功后

<块引用>

您应该在 php.ini 中添加extension=mcrypt.so"

如果您需要任何帮助，请在下方评论.:-)

<块引用>

重要提示！

根据 php.net 引用了许多(所有)mcrypt 函数有自 PHP 7.1.0 起已弃用.依靠这个功能是非常气馁.

As I'm trying to load mcrypt extension module from PHP 7.2.X version.
So I tried to make use of PECL library that is compatible to the current version of my PHP, in order to get installed and followed this link: Installing mcrypt on PHP 7.2 during installation!

These below are the result's obtained after executing certain commands on the terminal.

sudo: pecl7.2-sp: command not found

As I'm getting this type of Error as pecl7.2-sp: command not found

From the documentation section, it had been clearly stated that it had been deprecated and no longer will be available from the security point of view — since then, from the release version of PHP 7.2.X onward's.

But some of the project's need those dependencies, in order to carry out the required functionality as necessary. How do I need to solve the above issue?

UPDATE:

TL;DR:

I had a lot of response from the votes to the posted answer. The answers need to be triaged depending upon the OS Architecture level. Since I'm using the shared server for hosting, there are more than one projects residing over it & which are coded with the version of PHP 5.X.X, so I decided to downgrade to PHP 7.1.X that supports mcrypt extension by default in my Debian based OS.

As I already mentioned in the link while Installing mcrypt Extension on PHP 7.2, by Server Pilot community. These peoples had told a newer version of pecl-7.2 is available to install mcrypt on PHP-7.2. Unfortunately, it ended with pecl7.2-sp: command not found from the executed commands which were put up. Later the website page got an update, so the commands over there doesn't match the commands that were tried while executing.

Finally, whichever might be the solutions fit's to your OS Architecture level, Just go for it!.

OR

If the below approaches didn't yield to solve the root cause.
Alternatively, you can go for PHP 7.1.X version which supports mcrypt extension by default

解决方案

I followed below steps to install mcrypt for PHP7.2 using PECL.

1. Install PECL

apt-get install php-pecl

2. Before installing MCRYPT you must install libmcrypt

apt-get install libmcrypt-dev libreadline-dev

3. Install MCRYPT 1.0.1 using PECL

pecl install mcrypt-1.0.1

4. After the successful installation

You should add "extension=mcrypt.so" to php.ini

Please comment below if you need any assistance. :-)

IMPORTANT !

According to php.net reference many (all) mcrypt functions have been DEPRECATED as of PHP 7.1.0. Relying on this function is highly discouraged.
