I didn’t see PATH defined in PHP.net manual. It says PATH_TRANSLATED and PATH_INFO only.
I got following detail in print_r($_SERVER).
[PATH] => /sbin:/usr/sbin:/bin:/usr/bin

It is the value of the system’s
PATHenvironment variable, which is a list of folders that binary commands are looked for in. Runningecho $PATHin the terminal should yield the same (or similar, if under a different user) value.
