The usual mistake: I developed with the newest PHP version, while server has 5.3 ... and some errors appears.
Now I want to install Php 5.3 too, but Im affraid it would spoil the settings of 5.4, the registry entries, etc.... in other words, I want to be able to choose to start 5.3 or 5.4.... how to do it?
As far as I can recall php doesn't put anything of importance in the registry. The thing
that determines what version of php will be used is your server config (apache?).
I don't have a windows box nearby right now, but what I would investigate is if there are any
environment variables that are set, e.g. to pear directory. If you can't find
anything like that then you should be quite safe and the config of each php should reside
in files in the respective directory.

I just went from windows to mac and am now trying to import my local wordpress projects from xampp to mamp. I have some issues with my websites and I suspect it is because of the newer version of PHP that MAMP uses.
In the preferences MAMP offers "7.1.0" and "7.0.13" but when I change to the older version and click "save", MAMP restarts the servers and when I check the settings it is back to "7.1.0".
How can you fix this?
I was able to change the PHP Settings after changing the available PHP versions that MAMP offers. I did this by going to "/Applications/MAMP/bin/php" and renaming one of the folders, for example adding "_X" at the end. By renaming the folder of one of the 2 available PHP versions you remove it from the selection. Afterwards I was able to change and save the standard PHP version.
A bug was recently submitted on Mamp's Bugbase but it is unresolved at this moment. Meanwhile, the solution described by koedev, as well as the solutions found at the workaround cited by Arda Kazanci could be used.
Globally, two different solutions are available in the workaround cited by Kazanci: The koedev solution, that is, adding a _X in folder's name, and a second one that seems to be more professional, that is, adding an "extra" folder to httpd.conf and "selecting" inside which php versions should be used by mamp. Because some users didn't succeed in making work the extra configuration of httpd, it may be faster and simplest to follow the koedev solution.
I have VSCode installed, but don't seem to have php - i.e. there is no "php.exe" anywhere on my computer. No guides that I can find on the web about setting VSCode up for PHP suggests that I need to download and install php itself seperately (only debuggers and linters)... my question is:
Do I need to install PHP seperately? Should I have had to do this, or is there a bug in my VSCode installation...
Yes you need to install PHP from the php website and then tell VSCode where PHP.exe is located.
VSCode is an editor not an interpreter.
I think if you install PHP at the default location VSCode will automaticly pick it up but if not you need to specify its path in options.
If you install XAMPP you will get apache,php and mySql in one installation.
EDIT: an interpreter is software that translated your code(in your case PHP) into code that the CPU can understand and then executes.
#kpollock it' not you. Yes, it should seem obvious that the language should be installed manually or separately, so you should have gotten that part, sorry. But no, there doesn't seem to be information anywhere about defining the underpinnings. This "understanding" seems to be left to the individual through research as you're doing.
After I installed PHP I manually set my environment PATH to include the PHP folder. OR in VS Code you can go to menu>File>Preferences>User Settings, the settings are maintained as a JSON object (unlike VS) and there is a PHP section for the .exe path.
Since you mentioned Node, you may not have installed Node.js manually. (I don't know if Node comes with VS Code either.) It might have come in with a VS2015 extension like Gulp or some other higher-level functionality, or maybe it was an installation option with VSC. If you can't use node or npm from a console, set your environment PATH to include it.
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)
I am asp.net developer , i want to learn php
what are the software need to run compile php file ?
how to install this software any path that should be set ?
what kind of database it needs to store data and retrieve date ?
see me as beginner and then give the idea / information ..........
thanxx
You just need the PHP interpreter and if you want to do web stuff a webserver.
You can get the interpreter from http://www.php.net - if you are using windows you really want to get a binary version and not compile it on your own - and the Apache webserver.
As a database PHP developers usually use MySQL (but it can also connect to most other databases).
The easiest way for your to get started is getting a package like XAMPP which will contain all you need without requiring you to configure everything manually.
For actually learning PHP, please get a recent book/tutorial. Old stuff is usually telling people to do horribly things every sane developer will hate you for (cluttering your global namespace with variables settable by the user for example).
You could have a look at the official PHP docs which also contains a "getting started" guide.
Since you are an ASP.NET developer I assume that you are familiar with IIS and that you're probably using IIS 7.5. If so then the easiest way to familiarize yourself with PHP is to use Microsoft Web Platform Installer and install PHP directly to IIS. You don't have to set any paths after that, just create a site on IIS and start putting PHP files there. Keep in mind that Web Platform Installer automatically enables WinCache extension and your changes might not be there when you hit the refresh button. Just locate the php.ini and comment out the relevant line.
Straight from the horses mouth. Getting Started. You will need a php interpreter, if you have access to a webhost that has php installed you're half way there, if you have a linux partition you're half way there, otherwise check out XAMPP.
Software: XAMPP will get you up and running
Tutorial: w3schools
If you are familiar with IIS and want to use it as your web server you can download PHP for IIS here and use some of the learning material there to get started.
If you did not want to use IIS and wanted to use Apache instead then I agree with the others XAMPP will get you a dev environment up and running quickly.
I need to install or use php on a windows 2003 server that already has php 5.2.0.0 installed due (I think) to setting up symantec backup exec. I don't want to interfere with backup exec's php.ini settings - and would rather be able to control my own configuration of php.
searching for php shows that php.exe and other php files are currently installed in
c:\program files\symantec\backup exec\
I'm almost certain that installing the current version of php 5.2.8 to c:\php would be disastrous or calamitous in some way.
There is no PHPRC entry in the server properties > environment variables and I'm pretty sure that the php.exe location is not included in the PATH variable. ...unless the actuall install location is different from the c:\program files\symantec\backup exec\ dir.
Any suggestions on how to proceed?

What makes you say that :) I've run separate PHP versions on the same machine side by side and not run into bother.
AFAIK the Symantec install should not conflict with your own installation, nor should the separate php.ini files conflict with each other.
[Response to comment]
First thing to note is that I have no experience of Backup Exec or what it uses PHP for. I'm guessing it uses it for its own internal stuff and doesn't spread itself over the OS. Test this by searching for php.ini and php DLLs on the file system. I'm betting it's all quite self contained. PHP searches for the config file as noted here: PHP Site . As you note, BE hasn't set the PHPRC variable. Check it hasn't used those Registry entries either. On a different tack, has BE installed an admin site already on IIS? If so, check the IIS Web Service Extensions to make sure it hasn't already registered the PHP ISAPI dll or PHP CGI exe. IF not, I think you should be okay for your new install.
To be on the safe side, do a manual PHP install as illustrated here: PHP Site. That way, you know exactly what you have installed, and can easily remove the files again if they cause a problem. I can't imagine a problem here that would require you to reinstall BE.
