I'm running a VPS with centOS, plesk 12 and PHP5.3. I'm looking to upgrade to a more recent version of php but without taking down all my sites running on that server.
I've tried through the plesk GUI and got to this point which is ambiguous to what it will do. Is this the way to do it or will it delete my version of php 5 and replace it with something unknown?
Thanks for your help
Make sure that you have CentOS6 or 7 and latest Plesk microupdates installed. After that you will be able to safely use Multiple PHP feature in Plesk - http://kb.odin.com/125146

This is my issue and it has given me sleepless night.
I have been working on the wamp 2.1 server environment for the past 3 years and now i want to upgrade. I finally installed wamp 2.5 and would be willing to keep my previous wamp 2.1 version. everything looks good, because after installation, i did the following after:
Copied ?:\wamp_old\bin\apache to ?:\wamp\bin
Copied ?:\wamp_old\bin\mysql to ?:\wamp\bin
Copied ?:\wamp_old\bin\php to ?:\wamp\bin
Now, the issue is this:
Whenever i start the wamp server with the latest version, it works and the icon turns green. but whenever i try changing/switching back to the old version, all the services starts except the Apache. the icon stays orange and never turns green. whenever i click test port, it tells me your port 80 is not actually used. when i click on install service, i get this message: your port 80 is available, install will proceed. when i select remove service, it removes immediately. when i click start/resume service, nothing happens and it never starts.
What I want to achieve is this:
Some old joomla site were developed on the former wamp 2.1 and each time i tried accessing them via the new wamp 2.5, i see some deprecated functions and it display some chunks of codes. meanwhile, i have two projects that refuse to run on the old wamp 2.1, so i decided to run the 2.5. Presently, the system has wamp 2.5 running.
For 5 days now, i have been cracking my head and i have been stucked.. someone out there should please help me with a solution to run wamp 2.1 and wamp 2.5 together so i can switch version easily. or a probably solution will be appreciated.
Kind Regards !
You were on the right track copying the old Apache MySQL and PHP folders into the new 2.5 version.
Unfortunately switching to very old versions from the new ones is now a bit more hassle than it used to be because of the changes made in the version of compiler used to compile Apache and PHP.
Your old versions of Apache and PHP were compiled with MSVC6 and the new versions with MSVC11 and the 2 are not compatible i.e. an Apache compiled with VC11 wont run with a PHP compiled with VC6 etc.
So try this :-
Switch from Apache 2.4.9 to your old version, it wont start because the PHP version will still be 5.5.12.
Ignore the problem.
Now switch to an old version of PHP, thats compatible with the old Apache.
With luck it will now work.
Check you have the correct version by looking at phpinfo
If it does not come up re-do the switch to the old apache and then again to the old PHP by just re-clicking the version numbers on the relevant switch menu.
To be honest I don't know if it would be possible to restore everything to work fine. I had once similar problems - I had Wampserver and installed new PHP version for WAMP and switched to new PHP version and eveything stopped to work. I tried to change PHP version to the previous one but I had info it's not compatible with Apache and I couldn't change PHP version because of chosen PHP version.
Now I moved to easyPHP and it's much more easier, you can have many PHP versions, there's no problem with changing them.
Probably in your case the problem was not WAMP itself but PHP versions. That's why when you launched your older code you have many warnings. You should simple select older PHP version to do that or you simple have to turn off warning (maybe for other PHP version you had turned off displaying warnings by default?).
If I were you, I would move to easyPHP, dump your databases (if any) and move everything to easyPHP. Probably you won't make your installation of WAMPserver work so the other option is backup everything, dump your databases and reinstall WAMPserver but you can be almost sure similar problem occurs sooner or later when you will be switching between PHP versions.
After alot of brainstorming, I finally resolved the issue all by myself.
Though it may not look wise, but i believe it could go a long way to help others who are stucked in situations like this.
First, I started the wamp 2.5, changed all the versions to the latest ones, which is Apache, Mysql and Php... when the icon turned green, I decided to stop all services, uninstalled the services one after the other. (Apache and mysql) and exit the application by right clicking.
Secondly, I renamed the wamp which encapsulates the 2.5 version to wamp_2.5old and renamed the 2.1 folder back to wamp. i launched the wamp and installed the services back again..this time, it was a lower version. both php and apache had just one version while my sql had two. I made sure the right version of sql was selected and i installed it. I restarted all the services, the icon turned green and all my old website worked.
I tried the method vice-versa and all my latest projects worked. it might look challenging but thats my own way of discovering running multiple version of wamp.
Lastly, thanks to Özgür Eroğlu and Marcin Nabiałek.. they have been of helped.
Pleas help me flag this as useful for research..
vielen gluck.. good luck guys !
I have freshly installed Ubuntu 12.04 and I have installed PHP as well. By default, it is installed with version 5.3.10 but my PHP project doesn't support PHP v5.3.10.
I want to downgrade PHP version to 5.2. How can I do it?
You would have to uninstall PHP and then reinstall an older version. However if your working on a project that your going to sell, or give to clients, or whatever the case my suggestion would be take out any functionality thats actually breaking between 5.2x and 5.3x and replace it with its new counter parts, as most people will not want to revert to older versions of PHP for any needs, and generally speaking php versions only goin in one direction, if you block yourself into 5.2 and your making software in one shape or another for people, what are you going to do next year when all the servers come stock with PHP 6? Not to mention a lot of hosted solutions try to provide the latest and greatest on there new machines, and will not revert for a single client especially on a shared hosting environment.
Anyway yea, back to your question again in your terminal under Ubuntu, you can try the following. sudo apt-get purge php5 which will then prompt you for a password, then proceed with removing PHP assuming you have the PHP package standalone and not bundled in with some preconfigured LAMP stack, but then again it should still work generally speaking so long as the version is right.
As for reinstalling it, remove purge from the command and use install. However you will need to look up the means of getting an archived version installed of PHP as apt-get will get you the latest
I want instal the Php in My windows7 PC here i want use Apche webserver is there any simple way to install?
Thanks in Advance..
You can try http://www.wampserver.com/en/ (WAMP = Windows Apache MySql Php), it will integrates all you need (php + mysql + apache) including correct configuration
Also you can try http://www.apachefriends.org/en/xampp.html (XAMPP).
These packs will help you to install PHP, MySql and Apache without problems.
Agree with #michael-swan
i will suggest to go with XAMPP, since you can simply start the XAMPP server and you got apache/php/mysql working.
No need for any installation can be used in a portable drive too.
I am not sure if any such option is available in wamp, but it has easy to handle configs vars
Both the software are bundles of APACHE/PHP/MYSQL package - which are the complete package
You'll want to use a packaged distribution of Apache, MySQL, and PHP (WAMP) that's all configured and ready to host websites after a short automated install.
Start with this list of WAMPs: http://en.wikipedia.org/wiki/Comparison_of_WAMPs
It's the most comprehensive list and will give you some ideas about what's available.
The ones I've seen used most often are Xampp, WampServer, and UniformServer. There are also commercial ones like Wamp-Developer.
Try installing 3 of 4 different WAMPs and just trying them out one by one with 1) setting up a new website and 2) installing WordPress as a blog. This will give you a good idea of what works best for you.
I upgraded my system from Windows xp to windows 7. When i was in win xp i used the wamp server with php version 5.0 now i installed the wamp server with the version 5.3. But now it's making problem. The old projects are not running. Even-though they are created in php version 5. How i can solve this problem?
New versions of WAMP use apache 2.2.x and lovest php version supported for that is 5.2. That beeing said you can downgrade your php version of wamp installation by downloading a php addon http://www.wampserver.com/en/addons_php.php from here. Or you can ultimately downgrade WAMP apache installation from 2.2 to 2.0 http://www.wampserver.com/en/addons_apache.php . If your project don't work with 5.2 or 5.3 you need to debug and update your code with the latest changes in php http://php.net/migration53
There are some (but not many) backward-incompatible changes between PHP 5.0 and 5.3. But they're fairly obscure and not generally going to cause major issues. You can find the full details here: http://uk.php.net/manual/en/migration53.incompatible.php
However my guess is that it's more likely that you've installed the new version missing one or more extensions which your code is relying on.
For example, if you are using the pdo_xx() functions, you would need the PDO extension. Most PHP programs will use functionality from several extensions, and not all of them may be included in the default installation, so you need to ensure you have installed with all the ones you need.
The other possibility is that there's an issue with the installation (either PHP itself or the web server, etc) that is preventing PHP from running at all.
But this is all really a guess, because you haven't actually told us anything about what exactly the problem is. You need to look and see in what way it's failing. If you're not getting error messages in the browser, check the server error logs. This is the quickest way to diagnose the problem. It should give you some good clues (if it doesn't help you understand what's happening, paste the relevant log entries here, because they'll definitely make sense to someone)
How on earth does plesk actually work? I have a VPS which is on centos 5.2 and has php 5.1.6. I have updated plesk to version 9.52 and it claimed to do some form of php update but it hasn't as far as i can see. How can i update to php 5.2 (centos 5.4) without breaking plesk Virtuozzo?!
Plesk seems to be some kind of crazy black magic that i just don't understand.
Plesk uses whatever version of PHP is currently installed on the server.
You can update PHP to version 5.2 or higher from the IUS repository, but because Plesk looks in the RPM database specifically for the package "php" and not "php52" it will show that PHP is not installed, and PHP will break. I've gotten around this by compiling a dummy php package, with nothing in it, just called "php" so that Plesk won't disable PHP functionality, but that's not the best way to go.
