Re^2: How CGI works

if you stumble-upon a URL somewhere that contains the string, php, you can be 100% certain that what the web-server is doing is executing that PHP program

This is so very wrong.

It it were a file suffix indeed and the webserver configured to execute those pages with PHP, then that would work.
That is a somewhat common thing, but not ubiquitous.

Don't be so certain, as there are at least three biggish companies where ".php" web pages are run with perl and a templating engine.

The original PHP was even written in Perl. CountZero A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout.

Bah, hair splitting. Better as "The original version of PHP/FI, which evolved into PHP, was written in Perl"? ^[1] `[1]` Although the current PHP site docs state that PHP/FI was first written in C, older versions of that history stated that the first scripts were in Perl: http://svn.php.net/viewvc/phpdoc/en/trunk/appendices/history.xml?r1=64852&r2=65199&pathrev=314121 The way forward always starts with a minimal test.
