How can I get the path of the PHP binary from PHP?

Question

How can I get the binary path of `php` from PHP? I saw it in phpinfo(), but I need another method that gets it in Linux and Windows systems.

Accepted Answer

You can use:

```
$_SERVER['_']
```

Also, the predefined constant `PHP_BINDIR` gives the directory where the PHP executable is found.

Sample on CodePad and Ideone.

It looks like, for security reasons, `$_SERVER` values are not exposed.
