Introduction With the introduction of version 4.2, PHP has started supporting a new SAPI (Server Application Programming Interface) called CLI (Command Line Interface). This facility was introduced to help developers create small shell applications (scripts) with PHP. So, now you can kiss Perl goodbye forever. The CLI SAPI was released for the first time with PHP 4.2.0, but was still experimental back then and had to be explicitly enabled with --enable-cli when running...

One of the methods that the web server uses to pass information to a cgi script is through environmental variables. These are created and assigned appropriate values within the environment that the server spawns for the cgi script. They can be accessed as any other environmental variable, like with getenv() (in C) or %ENV{\'VARIABLE_NAME\'} (in Perl). Many of them, contain important information, that most cgi programs need to take into account. This list, highlights some of the most...

What is HTTP? HTTP is a client-server protocol by which two machines can communicate over a tcp/ip connection. An HTTP server is a program that sits listening on a machine\'s port for HTTP requests. An HTTP client (we will be using the terms HTTP client and web client interchangeably) opens a tcp/ip connection to the server via a socket, transmits a request for a document, then waits for a reply from the server. Once the request-reply sequence is completed, the socket is closed. So the...

To help me decide I did what any other programmer would do, I jumped into an IRC channel about Perl and started talking about driving versus flying. If you know anything about Perl IRC channels, this quickly escalated into a Holy War with Emacs users on one side and Jeep Wrangler drivers on the other. It was hard to tell...
