当系统中安装了多个php版本时，如何使用pecl为特定的php版本安装php扩展? [英] How to install php extension using pecl for specific php version, when several php versions installed in system?

问题描述

根据本手册，我已经在Ubuntu上从PPA安装了php5.6和php7.0

I have installed both php5.6 and php7.0 from PPA on Ubuntu according to this manual

http://lornajane.net/posts/2016/php-7-0-and-5-6-on-ubuntu

但是我没有得到如何使用pecl为php5.6或php7.0安装扩展的信息.

But I didn't get how to install extensions using pecl for php5.6 or php7.0.

例如，我已经在php5.6中安装了libevent或amqp版本.

For example I have already installed version of libevent or amqp in php5.6.

现在，当我键入pecl install libevent且我的活动php版本是php7.0时(使用已安装的update-alternatives --set php /usr/bin/php7.0), pecl returns message that libevent`.

Now when I type pecl install libevent and my active php version is php7.0 (using update-alternatives --set php /usr/bin/php7.0),peclreturns message thatlibevent` already installed.

但是它只为php5.6安装(当此版本处于活动状态时)，现在我想为php7.0安装它.

But it was installed only for php5.6 (when this version was active) and now I want to do it for php7.0.

哪些命令可以帮助我?

UPD

我发现以下命令可将pecl切换到php7.0并将其打包到可执行的bash脚本中:

I have found this commands for switch pecl to php7.0 and packet them to executable bash scripts:

#!/bin/bash

sudo update-alternatives --set php /usr/bin/php7.0

sudo pecl config-set php_ini /etc/php/7.0/cli/php.ini
sudo pecl config-set ext_dir /usr/lib/php/20151012/
sudo pecl config-set bin_dir /usr/bin/
sudo pecl config-set php_bin /usr/bin/php7.0
sudo pecl config-set php_suffix 7.0

和适用于php5.6

and for php5.6

#!/bin/bash

sudo update-alternatives --set php /usr/bin/php5.6

sudo pecl config-set php_ini /etc/php/5.6/cli/php.ini
sudo pecl config-set ext_dir /usr/lib/php/20131226/
sudo pecl config-set bin_dir /usr/bin/
sudo pecl config-set php_bin /usr/bin/php5.6
sudo pecl config-set php_suffix 5.6

但是它们无济于事，即使我切换到php7，pecl仍会给我list已安装的php5.6扩展名.

But they are not help, pecl still gives me list of already installed extensions to php5.6, even if I switched to php7.

pecl list
Installed packages, channel pecl.php.net:
=========================================
Package  Version State
amqp     1.7.1   stable
libevent 0.1.0   beta
stats    1.0.3   stable

对于php7.0应该为空！

It should be empty for php7.0 !

如何解决问题?

UPD

对于amqp，我刚刚安装了php-amqp软件包，而没有使用pecl.

For amqp I have just installed php-amqp package without using pecl.

apt-get install php-amqp

并且php7的libevent仍然不存在. 但是我还没有找到在5.6和7版本之间切换pecl安装的方法，因此问题仍然悬而未决.

And libevent still not exists for php7. But I hadn't found a way to switch pecl installation between 5.6 and 7 version, so question is still open.

推荐答案

在尝试编写此脚本时，这是最适合我的方法(以防其他人像我那样遇到此问题):

Here's what worked best for me when trying to script this (in case anyone else comes across this like I did):

$ pecl -d php_suffix=5.6 install <package>
$ pecl uninstall -r <package>

$ pecl -d php_suffix=7.0 install <package>
$ pecl uninstall -r <package>

$ pecl -d php_suffix=7.1 install <package>
$ pecl uninstall -r <package>

-d php_suffix=<version>件允许您在运行时设置配置值，而不是用pecl config-set预先设置它们. uninstall -r位实际上并没有从文档中卸载它:

The -d php_suffix=<version> piece allows you to set config values at run time vs pre-setting them with pecl config-set. The uninstall -r bit does not actually uninstall it (from the docs):

vagrant@homestead:~$ pecl help uninstall
pecl uninstall [options] [channel/]<package> ...
Uninstalls one or more PEAR packages.  More than one package may be
specified at once.  Prefix with channel name to uninstall from a
channel not in your default channel (pecl.php.net)

Options:
  ...
  -r, --register-only
        do not remove files, only register the packages as not installed
  ...

卸载行是必需的，否则即使安装了其他PHP版本，也要安装它会删除任何以前安装的版本(例如:如果软件包仍注册为已安装，则安装PHP 7.0的扩展名将删除5.6版本)

The uninstall line is necessary otherwise installing it will remove any previously installed version, even if it was for a different PHP version (ex: Installing an extension for PHP 7.0 would remove the 5.6 version if the package was still registered as installed).
