How can one run multiple versions of PHP 5 x on a development LAMP server

Question

I need to test my PHP applications with multiple versions of PHP 5 x  such as PHP 5 0 0 and PHP 5 2 8   Is there a way that I can configure a development LAMP server so I can quickly test applications with multiple versions of PHP5

Note  The following method will work on windows   An alternative method  if it is ok to run a single version of PHP at a time  is to define multiple Apache services  each of which will use a different PHP version   First of all use conditions in the Apache configuration file     lt ifdefine php54 gt      SetEnv PHPRC C  apache php54      ScriptAlias  php   C  apache php54       AddType application x-httpd-php  php     Action application x-httpd-php   php php-cgi exe   lt  ifdefine gt    lt ifdefine php55 gt      SetEnv PHPRC C  apache php55      ScriptAlias  php   C  apache php55       AddType application x-httpd-php  php     Action application x-httpd-php   php php-cgi exe   lt  ifdefine gt    Now using the httpd exe create two separate services from command line  elevated to administrator    httpd exe -k install -n Apache224 php54 -D php54  httpd exe -k install -n Apache224 php55 -D php55   Now you can start one of the above services at a time  should shutdown one before starting the other    If you have previously installed Apache as service you can remove that using below command  replace the service name with the one you have used    apache -k uninstall -n Apache224   One further note is that I personally use a  notification area icon program  called  Seobiseu  to start and stop services as needed  I have added the two above services to it

Understanding that you re probably talking about a local desktop machine and would probably like to continue talking about a local desktop machine  I ll throw an alternative out there for you just in case it might help you or someone else   Set up multiple virtual server instances in the cloud  and share your code between them as a git repository  or mercurial  I suppose  though I have no personal experience all you really need is something decentralized    This has the benefit of giving you as close to a production experience as possible  and if you have experience setting up servers then it s not that complicated  or expensive  if you just want to spin a server up  do what you need to do  then spin it down again  then you re talking about a few cents up to say 50 cents  up to a few bucks if you just leave it running    I do all of my project development in the cloud these days and I ve found it much simpler to manage the infrastructure than I ever did when using local non-virtualized installs  and it makes this sort of side-by-side scenario fairly straight forward   I just wanted to throw the idea out there if you hadn t considered it

For testing I just run multiple instances of httpd on different IP addresses  so I have php7 running on 192 168 0 70 and php5 6 running on 192 168 0 56  In production I have a site running an old oscommerce running php5 3 and I just have a different conf file for the site   httpd -f  etc apache2 php70 conf httpd -f  etc apache2 php53 conf   It s also a clean way to have different php ini files for different sites  If you just have a couple of sites if a nice way to keep things organized and you don t have to worry about more then 1 site at a time when you upgrade something

I have just successfully downgraded from PHP5 3 on Ubuntu 10   To do this I used the following script        bin sh php packages  dpkg -l   grep php   awk   print  2     sudo apt-get remove  php packages  sed s lucid karmic g  etc apt sources list   sudo tee  etc apt sources list d karmic list  sudo mkdir -p  etc apt preferences d   for package in  php packages  do echo  Package   package Pin  release a karmic Pin-Priority  991     sudo tee -a  etc apt preferences d php done  sudo apt-get update  sudo apt-get install  php packages   For anyone that doesn t know how to run scripts from the command line  here is a brief tutorial   1  cd    2  mkdir bin 3  sudo nano   bin myscriptname sh 4  paste in the script code I have posted above this 5  ctrl x  this exits and prompts for you to save  6  chmod u x myscriptname sh   These 6 steps create a script in a folder called  bin  in your home directory  You can then run this script by calling the following command      bin myscriptname sh   Oulia   Hope this helps some of you   For reference  here is where I got the script  PHP5 2 10 for Ubuntu 10  There are several people on there all confirming that this works  and it worked a treat for me

Rasmus Lerdorf  who created PHP  is maintaining an active Vagrant solution that seems to solve your needs  It allows for quickly switching between PHP versions  currently supporting more than 20 different versions  It comes out of the box with an nginx server  but can easily be switched to apache2 with a preconfigured setting  It also supports MySQL out of the box   This way you will have access to all versions of PHP  deployable on two of the main web servers  in a nice vagrant box  maintained by the big man behind PHP   For more information I would like to refer to the talk given by mr  Lerdorf at https   youtu be 6XnysJAyThs t 2864  The github repository containing the Vagrant solution is found at https   github com rlerdorf php7dev

I have several projects running on my box   If you have already installed more than one version  this bash script should help you easily switch   At the moment I have php5  php5 6  and php7 0 which I often swtich back and forth depending on the project I am working on   Here is my code     Feel free to copy   Make sure you understand how the code works   This is for the webhostin   my local box my mods are stored at  etc apache2 mods-enabled          bin bash   This file is for switching php versions      To run this file you must use bash  not sh          OS  Ubuntu 14 04 but should work on any linux   Example  bash phpswitch sh 7 0   Written by Daniel Pflieger   growlingflea at g mail dot com  NEWVERSION  1   this is the git directory target   get the active php enabled mod by getting the array of files and store  it to a variable VAR   ls  etc apache2 mods-enabled php     parse the returned variables and get the version of php that is active  IFS     read -r -a array  lt  lt  lt    VAR  array 0    array 0   php  array 0    array 0   conf     confirm that the newversion veriable isn t empty   if it is tell user   current version and exit if     NEWVERSION          then echo current version is   array 0     To change version please use argument exit 1 fi   OLDVERSION   array 0    confirm to the user this is what they want to do echo  Update php     OLDVERSION  to   NEWVERSION     give the user the opportunity to use CTRL-C to exit ot just hit return read x   call a2dismod function  this deactivate the current php version sudo a2dismod php  OLDVERSION    call the a2enmod version   This enables the new mode sudo a2enmod php  NEWVERSION    echo  Restart service    read x   restart apache sudo service apache2 restart

With CentOS  you can do it using a combination of fastcgi for one version of PHP  and php-fpm for the other  as described here   https   web archive org web 20130707085630 http   linuxplayer org 2011 05 intall-multiple-version-of-php-on-one-server  Based on CentOS 5 6  for Apache only  1  Enable rpmforge and epel yum repository  wget http   packages sw be rpmforge-release rpmforge-release-0 5 2-2 el5 rf x86 64 rpm wget http   download fedora redhat com pub epel 5 x86 64 epel-release-5-4 noarch rpm sudo rpm -ivh rpmforge-release-0 5 2-2 el5 rf x86 64 rpm sudo rpm -ivh epel-release-5-4 noarch rpm   2  Install php-5 1  CentOS RHEL 5 x series have php-5 1 in box  simply install it with yum  eg   sudo yum install php php-mysql php-mbstring php-mcrypt   3  Compile and install php 5 2 and 5 3 from source  For php 5 2 and 5 3  we can find many rpm packages on the Internet  However  they all conflict with the php which comes with CentOS  so  we   d better build and install them from soure  this is not difficult  the point is to install php at different location    However  when install php as an apache module  we can only use one version of php at the same time  If we need to run different version of php on the same server  at the same time  for example  different virtual host may need different version of php  Fortunately  the cool FastCGI and PHP-FPM can help   Build and

view phpinfo and validate the result  ie   http   web1 example com http   web2 example com http   web3 example com   If all OK  you can use one of the 3 virtual host as template to create new virtual host  with the desired php version

Having multiple instances of apache   php never really tickled my fancy  but it probably the easiest way to do it  If you don t feel like KISS     here s an idea   Get your apache up and running  and try do configure it like debian and ubuntu do it  eg  have directories for loaded modules  Your apache conf can use lines like this   Include  etc apache2 mods-enabled   load Include  etc apache2 mods-enabled   conf   Then build your first version of php  and give it a prefix that has the version number explicitly contained  eg   usr local php 5 2 8   usr local php 5 2 6      The conf load would look something like this   php5 2 6 load  LoadModule php5 module  usr local php 5 2 6 libphp5 so   php5 2 8 load  LoadModule php5 module  usr local php 5 2 8 libphp5 so   To switch versions  all you have to do is change the load and conf files from the directory apache does the include on for the ones for another version  You can automate that with a simple bash script  delete the actual file  copy the alternate versions file in place  and restart apache   One advantage of this setup is the everything is consitent  so long you keep the php ini s the same in terms of options and modules  which you would have to do with CGI anyway   They re all going through SAPI  Your applications won t need any changes whatsoever  nor need to use relative URLs   I think this should work  but then again  i haven t tried it  nor am i likely to do so as i don t have the same requirements as you  Do comment if you ever do try though

One way to do this is to have your main version of php set up with mod php and run all of the others through fast cgi on different ports  i e  81  82  83 etc   This won t guarantee totally consistent behavior though
