can be used for Command Line Scripting – do not
need a browser or server, only the PHP parser.
examples are CRONs on Linux, Task Scheduler on
Windows, simple text processing tasks.
not ideal, but can be used to write Desktop
Applications using an extension such as PHP-GTK.

Rasmus Lerdorf in 1994 to replace Perl scripts he’d been using for
his website (syntax is similar to Perl, but more limited and simpler)
since PHP 2 - form handling, ability to embed HTML,
communication with DB’s
in 1998 the parser was rewritten by Zeev Suraski and Andi
Gutmans to form PHP 3
heavily influenced by C, Perl, Java, C++, C#, Python
has become widely used as an alternative to Microsoft’s ASP
