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.

Answer 1

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.
