我想在 php 5.2.x 上运行特定版本的代码，我已经尝试了很多方法但都没有成功。
请告诉我如何在 ubuntu 14.04 上安装 PHP 5.2
答案1
在 Ubuntu 14.04 上安装 PHP 5.2.17
基于： http://www.rasyid.net/2014/10/07/using-multiple-php-inside-one-ubuntu-machine/添加 PostgreSQL Apt 存储库（提供 postgresql-server-dev-9.4）
apt-get install -y wget
echo "deb http://apt.postgresql.org/pub/repos/apt/ trusty-pgdg main" > /etc/apt/sources.list.d/pgdg.list
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
安装依赖项
apt-get update
apt-get install -y gcc make build-essential \
libxml2-dev libcurl4-openssl-dev libpcre3-dev libbz2-dev libjpeg- dev \
libpng12-dev libfreetype6-dev libt1-dev libmcrypt-dev libmhash-dev \
freetds-dev libmysqlclient-dev unixodbc-dev postgresql-server-dev-9.4 \
libxslt1-dev
需要防止在编译 freetype 支持时出现问题
mkdir -pv /usr/include/freetype2/freetype
ln -sf /usr/include/freetype2/freetype.h /usr/include/freetype2/freetype/freetype.h
下载 PHP 源代码
wget -c -t 3 -O ./php-5.2.17.tar.gz http://museum.php.net/php5/php-5.2.17.tar.gz
tar xvfz php-5.2.17.tar.gz
cd php-5.2.17
补丁 PHP
wget -c -t 3 -O ./libxml29_compat.patch https://mail.gnome.org/archives/xml/2012-August/txtbgxGXAvz4N.txt
patch -p0 -b < libxml29_compat.patch
wget -c -t 3 -O ./debian_patches_disable_SSLv2_for_openssl_1_0_0.patch https://bugs.php.net/patch-display.php\?bug_id\=54736\&patch\=debian_patches_disable_SSLv2_for_openssl_1_0_0.patch\&revision=1305414559\&download\=1
patch -p1 -b < debian_patches_disable_SSLv2_for_openssl_1_0_0.patch
wget -c -t 3 -O - http://php-fpm.org/downloads/php-5.2.17-fpm-0.5.14.diff.gz | gunzip > ./php-5.2.17-fpm-0.5.14.patch
patch -p1 < php-5.2.17-fpm-0.5.14.patch
编译并安装

答案2
您可以让 Ubuntu 14.04 (Trusty Tahr) 使用 Ubuntu 9.10 (Karmic Koala) 中的软件包轻松安装 PHP 5.2。这就是我在 Ubuntu 14.04.3 上安装 PHP 5.2.10 的方法。
步骤1
karmic.list创建一个文件/etc/apt/sources.list.d/并添加以下内容：
deb http://old-releases.ubuntu.com/ubuntu/ karmic main restricted
deb-src http://old-releases.ubuntu.com/ubuntu/ karmic main restricted
deb http://old-releases.ubuntu.com/ubuntu/ karmic-updates main restricted
deb-src http://old-releases.ubuntu.com/ubuntu/ karmic-updates main restricted
deb http://old-releases.ubuntu.com/ubuntu/ karmic universe
deb-src http://old-releases.ubuntu.com/ubuntu/ karmic universe
deb http://old-releases.ubuntu.com/ubuntu/ karmic-updates universe
deb-src http://old-releases.ubuntu.com/ubuntu/ karmic-updates universe
deb http://old-releases.ubuntu.com/ubuntu/ karmic multiverse
deb-src http://old-releases.ubuntu.com/ubuntu/ karmic multiverse
deb http://old-releases.ubuntu.com/ubuntu/ karmic-updates multiverse
deb-src http://old-releases.ubuntu.com/ubuntu/ karmic-updates multiverse
deb http://old-releases.ubuntu.com/ubuntu karmic-security main restricted
deb-src http://old-releases.ubuntu.com/ubuntu karmic-security main restricted
deb http://old-releases.ubuntu.com/ubuntu karmic-security universe
deb-src http://old-releases.ubuntu.com/ubuntu karmic-security universe
deb http://old-releases.ubuntu.com/ubuntu karmic-security multiverse
deb-src http://old-releases.ubuntu.com/ubuntu karmic-security multiverse
第2步
然后，创建另一个文件，php5_2内容/etc/apt/preferences.d/如下：
Package: apache2*
Pin: release a=karmic
Pin-Priority: 991
Package: php5
Pin: release a=karmic
Pin-Priority: 991
Package: libapache2-mod-php5
Pin: release a=karmic
Pin-Priority: 991
Package: libapache2-mod-php5filter
Pin: release a=karmic
Pin-Priority: 991
Package: php-pear
Pin: release a=karmic
Pin-Priority: 991
Package: php5-cgi
Pin: release a=karmic
Pin-Priority: 991
Package: php5-cli
Pin: release a=karmic
Pin-Priority: 991
Package: php5-common
Pin: release a=karmic
Pin-Priority: 991
Package: php5-curl
Pin: release a=karmic
Pin-Priority: 991
Package: php5-dbg
Pin: release a=karmic
Pin-Priority: 991
Package: php5-dev
Pin: release a=karmic
Pin-Priority: 991
Package: php5-gd
Pin: release a=karmic
Pin-Priority: 991
Package: php5-gmp
Pin: release a=karmic
Pin-Priority: 991
Package: php5-mhash
Pin: release a=karmic
Pin-Priority: 991
Package: php5-mysql
Pin: release a=karmic
Pin-Priority: 991
Package: php5-odbc
Pin: release a=karmic
Pin-Priority: 991
Package: php5-pgsql
Pin: release a=karmic
Pin-Priority: 991
Package: php5-pspell
Pin: release a=karmic
Pin-Priority: 991
Package: php5-recode
Pin: release a=karmic
Pin-Priority: 991
Package: php5-snmp
Pin: release a=karmic
Pin-Priority: 991
Package: php5-sqlite
Pin: release a=karmic
Pin-Priority: 991
Package: php5-sybase
Pin: release a=karmic
Pin-Priority: 991
Package: php5-tidy
Pin: release a=karmic
Pin-Priority: 991
Package: php5-xmlrpc
Pin: release a=karmic
Pin-Priority: 991
Package: php5-xsl
Pin: release a=karmic
Pin-Priority: 991
步骤3
然后，运行sudo apt-get update并最后使用以下命令安装它们（示例）：
sudo apt-get install apache2 libapache2-mod-php5 php-pear php5-curl php5-dbg php5-mhash php5-mysql php5-tidy php5-xmlrpc php5-xsl
p/s：您可以在上面的安装命令中添加其他 php 扩展，但只能添加php5_2首选项文件中定义的扩展，否则将安装错误的版本。
