Chapter 75. Migrating from PHP 3 to PHP 4

PHP has already a long history behind him : Legendary PHP 1.0, PHP/FI, PHP 3.0 and PHP 4.0.

1. Migrating from PHP 3 to PHP 4
2. Do sessions work in PHP 3?
3. Incompatible functions?

1. Migrating from PHP 3 to PHP 4

PHP 4 was designed to be as compatible with earlier versions of PHP as possible and very little functionality was broken in the process. If you're really unsure about compatibility you should install PHP 4 in a test environment and run your scripts there.

Also see the appropriate migration appendix of this manual.

2. Do sessions work in PHP 3?

Although native session support didn't exist in PHP 3, there are third-party applications that did (and still do) offer session functionality. The most common method was by using PHPLIB.

3. Incompatible functions?

Since PHP 4 is basically a rewrite of the entire PHP engine there were very few functions that were altered and only then some of the more exotic ones.
