What does php.exe found in the PHP directory do?

It is the command line processor that processes a file with the .PHP extension as shown here:
------------------------------
C:\Windows\system32>php "C:\inetpub\wwwroot\phpinfo.php" > "C:\info"
----------------------------
The PHP processor processes the provied php file and the command line directs the result to a file "info'

The input file phpinfo.php is as shown here:
----------
phpinfo();
?>
----------
The above file is typed into Notepad and saved with the extension ".PHP".

Here is the beginning section of the long file 'info' opened in Windows Word program.
