<?php class StudlyCaps { function StudlyCaps() { } function camelCase() { } function lower() { } function UPPER() { } } print PHP_VERSION . ": ". implode(" ", get_class_methods("StudlyCaps")) . "\n";
PHP4 lowercases class and function names:
$ /opt/php441/bin/php studly.php 4.4.1: studlycaps camelcase lower upper
But PHP5 retains the case:
$ /opt/php51/bin/php studly.php 5.1.2: StudlyCaps camelCase lower UPPER
