Some recipes for switching between underscore and camelcase naming:
<?php
// underscored to upper-camelcase
// e.g. "this_method_name" -> "ThisMethodName"
preg_replace('/(?:^|_)(.?)/e',"strtoupper('$1')",$string);
// underscored to lower-camelcase
// e.g. "this_method_name" -> "thisMethodName"
preg_replace('/_(.?)/e',"strtoupper('$1')",$string);
// camelcase (lower or upper) to underscored
// e.g. "thisMethodName" -> "this_method_name"
// e.g. "ThisMethodName" -> "this_method_name"
strtolower(preg_replace('/([^A-Z])([A-Z])/', "$1_$2", $string));
?>
Of course these aren't 100% symmetric. For example...
* this_is_a_string -> ThisIsAString -> this_is_astring
* GetURLForString -> get_urlfor_string -> GetUrlforString
