PHP is not recognized as an internal or external command in command prompt

问题

I got the following error when I run a command with php

C:\xampp\htdocs>php
'php' is not recognized as an internal or external command,
operable program or batch file.

I don't get any error when I run the command with php in following path:

C:\xampp\php>php  //do not got error here

Why I get this error?

回答1:

Add C:\xampp\php to your PATH environment variable.

Then close your command prompt and restart again.

It is very important because if you do not restart your command prompt then changes will not be reflected.

You need to Go to My Computer->properties -> Advanced system setting

Now click on Environment Variables

Add ;C:\xampp\php in path variable value

Now restart command prompt DONE!

Note: Make sure you run CMD via run as administrator

You just need to a add the path of your PHP file. In case you are using wamp or have not installed it on the C drive.

Set "C:\xampp\php" in your PATH Environment Variable. Then restart CMD prompt.

Is your path correctly configured?

In Windows, you can do that as described here:

You need to add C:\xampp\php to your PATH Environment Variable, Only after then you would be able to execute php command line from outside php_home.

I also got the following error when I run a command with PHP, I did the solution like that:

1. From the desktop, right-click the Computer icon.
2. Choose Properties from the context menu.
3. Click the Advanced system settings link.
4. Click Environment Variables. In the section System Variables, find the PATH environment variable and select it. Click Edit. If the PATH environment variable does not exist, click New.
5. In the Edit System Variable window, Add C:\xampp\php to your PATH Environment Variable.

Very important note: restart command prompt
