Hello everyone,

I am writing a paper for a computer science course I'm taking at the University of Toronto. I am to write a 1,100, fairly technical essay. I have chosen to profile PHP and trace it's development. I roughly know how it went (PHP/FI -> PHP/FI 2.0 -> PHP3 -> PHP4 -> PHP5). I know the main differences between the versions. However, I ge tthe feeling that it isn't enough. Can someone point me to a credible souce(s) that have good technical (as oppossed to social commentary) profiles of php? I'd really appreciate it.

Thanks!

I read once that PHP started off as a Perl script :P

Have you tried searching google?

PHP History

It's a little brief but might get you going in the right direction.

Yeah, I read that...I also read this: http://www.hudzilla.org/phpbook/read.php/2_1_2

I am looking for something that perhaps will tell me new features that were added between versions (without me digging through long CHANGELOG files of PHP), technical differences, why there were huge speed increases between PHP3 and PHP4 (aside from the fact that "Zend engine was introduced"...etc.

Thanks. :)

If you need inspiration you can also look at the CHANGELOG.. :)

Eg: How has the php lexing and parsing evolved? What is the role of the Zend Engine 1 and 2 in this story?
