如何构建PHP 5.6的mysql扩展？

标签： php mysql pecl phpize

我正在努力并排安装PHP 5.6和7.0，以便于从PHP 5迁移到7。

我正在使用OndřejSurý的Ubuntu PPA https://launchpad.net/~ondrej/+archive/ubuntu/php，它提供了PHP 5.6和7.0的可共同安装版本。

两个PHP版本并行工作，但有一个障碍：我无法为PHP 5.6构建mysql扩展名（即使我能够为7.0构建它）。 / p>

（我很清楚mysql扩展已经过时了，应该放弃它以支持更现代的替代方案。然而，我认为遗留应用程序依赖于它的客户是不合理的。重构他们的代码，而PHP 5.6仍然受支持。所以，我在这个问题上没有多少选择...）

对于不熟悉这种可共同安装的PPA的人，版本号会附加到二进制文件中，因此各种PHP可执行文件的路径如下：

# ls -lah /usr/bin | grep "php"
-rwxr-xr-x  1 root   root     13K Dec 31 03:24 dh_php
lrwxrwxrwx  1 root   root      21 Feb 23 09:51 php -> /etc/alternatives/php
-rwxr-xr-x  1 root   root    3.6M Feb 23 06:37 php5.6

-rwxr-xr-x  1 root   root    4.1K Feb 23 06:37 php-config5.6
-rwxr-xr-x  1 root   root    4.2K Feb 23 06:58 php-config7.0
lrwxrwxrwx  1 root   root      24 Feb 23 10:06 phpize -> /etc/alternatives/phpize
-rwxr-xr-x  1 root   root    4.7K Feb 23 06:37 phpize5.6
-rwxr-xr-x  1 root   root    4.6K Feb 23 06:58 phpize7.0

这是我尝试过的：

# git clone https://git.php.net/repository/pecl/database/mysql.git

# cd mysql

到目前为止，非常好。

问题发生在make期间。我只包含了一部分输出，因为我确信重复出现相同的问题。

似乎mysql扩展程序的源代码不再与PHP 5.6 API兼容。

鉴于mysql扩展在同一服务器上的PHP 7.0下编译完全正常，我们必须想知道扩展源是否已更新为使用7.0。

我尝试查找mysql扩展程序代码的早期版本，但https://pecl.php.net/package/mysql仅将用户引用到http://git.php.net/?p=pecl/database/mysql.git;a=summary，其似乎没有任何有意义的版本历史记录，例如较旧的分支旨在与PHP一起使用＆lt; 7.0。

我还能尝试什么？也许我忽视了一些愚蠢的事情......

感谢您的任何建议！

更新：解决方案

根据接受的答案，当我需要PHP 5.6源代码时，我正在获取PHP 7源代码。

这是解决方案（务必根据需要调整自己的版本，路径和服务命令）：

# git clone --depth=1 -b PHP-5.6 https://git.php.net/repository/php-src.git
# cd ./php-src/ext/mysql
# phpize5.6
#./configure --with-php-config=/usr/bin/php-config5.6
# make
# make install
# printf "; configuration for php mysql module\n; priority=20\nextension=mysql.so" > /etc/php/mods-available/mysql.ini
# ln -s /etc/php/mods-available/mysql.ini /etc/php/5.6/fpm/conf.d/20-mysql.ini
# service php5.6-fpm reload

答案 0 :(得分：4)

您正在使用PHP 5.6构建PHP 7扩展源。你必须获取5.6个来源。一种方法可能是从php-src.git或源分发tarball中获取5.6分支，然后在ext / mysql目录中运行phpize。

$ git clone -b PHP_5_6 git@git.php.net:/php-src.git php-5.6
$ cd php-5.6/ext/mysql
$ phpize5.6
