You can check if the directory separator is <code>/</code> (for unix/linux/mac) or <code>\</code> on windows. The constant name is <code>DIRECTORY_SEPARATOR</code>.

<pre><code>if (DIRECTORY_SEPARATOR === '/') {
 // unix, linux, mac
}

if (DIRECTORY_SEPARATOR === '\\') {
 // windows
}
</code></pre>

}|type|code-block|depth|inlineStyleRanges|entityRanges|data|syntax|javascript|910270|看起来比公认的答案更优雅一些。不过，使用DIRECTORY_SEPARATOR进行上述检测是最快的。|unstyled|910271|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$B|C]]|$1|D|3|E|5|F|7|J|8|@]|9|@]|A|$]]|$1|G|3|-4|5|F|7|K|8|@]|9|@]|A|$]]]|H|$]]

<pre><code>if (strncasecmp(PHP_OS, 'WIN', 3) == 0) {
 echo 'This is a server using Windows!';
} else {
 echo 'This is a server not using Windows!';
}
</code></pre>

seems like a bit more elegant than the accepted answer. The aforementioned detection with DIRECTORY_SEPARATOR is the fastest, though.

Starting with PHP 7.2.0 you can detect the running O.S. using the constant <code>PHP_OS_FAMILY</code>:

<pre><code>if (PHP_OS_FAMILY === "Windows") {
 echo "Running on Windows";
} elseif (PHP_OS_FAMILY === "Linux") {
 echo "Running on Linux";
}
</code></pre>

See the <a href="https://www.php.net/manual/reserved.constants.php#constant.php-os-family" rel="noreferrer">official PHP documentation</a> for its possible values.

The <a href="http://php.net/manual/en/function.php-uname.php" rel="noreferrer">php_uname</a> function can be used to detect this.

<pre><code>echo php_uname();
</code></pre>

blocks|key|694251|text|这应该可以在PHP+4.3%2B中工作：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|694252|if+(strtolower(PHP_SHLIB_SUFFIX)+===+'dll')

This should work in PHP 4.3+:

<pre><code>if (strtolower(PHP_SHLIB_SUFFIX) === 'dll')
{
 // Windows
}
else
{
 // Linux/UNIX/OS X
}
</code></pre>

blocks|key|694303|text|要检测它是Windows、OS+X还是Linux：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|694304|if+(stripos(PHP_OS,+'win')+===+0)+{

}|code-block|syntax|javascript|694305|在这种情况下，stripos比substr慢一点，但对于这样一个小任务来说，它已经足够高效了，而且更优雅。|offset|length|style|CODE|694306|entityMap^0|0|0|7|7|F|6|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@$I|R|J|S|K|L]|$I|T|J|U|K|L]]|9|@]|A|$]]|$1|M|3|-4|5|6|7|V|8|@]|9|@]|A|$]]]|N|$]]

To detect whether it's Windows, OS X or Linux:

<pre><code>if (stripos(PHP_OS, 'win') === 0) {
 // code for windows
} elseif (stripos(PHP_OS, 'darwin') === 0) {
 // code for OS X
} elseif (stripos(PHP_OS, 'linux') === 0) {
 // code for Linux
}
</code></pre>

<code>stripos</code> is a bit slower than <code>substr</code> in this particular case, yet it's efficient enough for such a small task, and more elegant.

I have a PHP script that may be placed on a windows system or a linux system. I need to run different commands in either case. 

How can I detect which environment I am in? (preferably something PHP rather than clever system hacks)

<h2>Update</h2>

To clarify, the script is running from the command line.

PHP script - detect whether running under linux or Windows?

Windows

Linux

我有一个PHP脚本，可以放在windows系统或linux系统上。在这两种情况下，我都需要运行不同的命令。如何检测我所处的环境？(最好是一些PHP，而不是聪明的系统黑客)更新为了清楚起见，该脚本是从命令行运行的。
