如何在 Windows 上确定 php.exe 的路径 - 搜索默认路径

Question

I'm currently developing a couple of plugins for Sublime Text 2 on OS X and I would like to make them cross platform, meaning I have to find out if and where php.exe is installed.

Right now I call /usr/bin/php in Python, which obviously works only on OS X and Linux:

phppath = '/usr/bin/php'<br>
pluginpath = sublime.packages_path() + '/HtmlTidy/tidy.php'<br>
retval = os.system( '%s "%s"' % ( phppath, scriptpath ) )

But on Windows, there seems to be no definitive default path for php.exe. The more I googled for it, the more possibilities showed up. So far I think I would have to check each of the following paths for existence:

c:\php\php.exe
c:\php5\php.exe
c:\windows\php.exe
c:\program files\php\php.exe
c:\wamp\bin\php\php5\php.exe
c:\xampp\php\php.exe

That's already quite a collection, but what I'm asking for is either a complete list covering all possibilities - or another way to figure it out that should be as robust as checking each possible path.

So if you have php.exe installed in some place other than these, please leave a comment with your path and I will add it to the list above.

Besides, there seems to be php.exe and php-cli.exe . I guess it would be OK to loop through each possible path. Check first for php-cli.exe, check for php.exe, and take the first match. Is that correct or is there a better practice?

Answer 1

If the user has added PHP's bin folder to the system PATH , then you should just be able to try and execute php -v to check that it's present.

If you want to obtain the full path to the PHP executable and the target system is Windows Server 2003 or later (so Windows Vista , and Windows 7 ) then you could use the WHERE command, ie:

C:\> where php.exe
C:\Program Files (x86)\WAMP\bin\php\php5.3.5\php.exe

Also see possibly related question: Is there an equivalent of 'which' on the Windows command line? .

If you are really desperate to find any file on the user's computer, you could try executing the equivalent of a find - but it's going to be slooow !

C: && cd \ && dir /s /b php.exe

Answer 2

从 PHP 5.4 及更高版本开始，您可以使用 PHP_BINARY 常量。

Answer 3

On powershell or commad prompt php -r "echo PHP_VERSION;" gives the version

See other PHP constantas: https://www.php.net/manual/es/reserved.constants.php

to answer your question

php -r "echo PHP_BINARY;" gives the full path to php.exe

if needed, to remove the php.exe

php -r "echo str_replace('php.exe', '', PHP_BINARY);"

Answer 4

Use:

C:\xampp\php\php.exe

It should work if your XAMPP instance is on D: or E: . You change it accordingly from C: .

Answer 5

Try

echo PHP_BINDIR;

It works. I tested it on macOS as with PHP 5.6.
