Chapter 37 php manual

Hi at php net Please forward to the right person. Wouldn't it be good if you were to state what the "few functions" are in point 2. Incompatible functions... especially if there aren't many differences? Best wishes from Hamburg Alan Frostick Chapter 37. 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/Zend 4.0. 1. Migrating from PHP3 to PHP4 2. Incompatibles functions? 1. Migrating from PHP3 to PHP4 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. 2. Incompatibles functions? Since PHP 4 is basically a rewrite of the entire PHP engine there was very few functions that were altered and only then some of the more exotic ones.
