<function>get_class</function> starting PHP 5 returns the name of the
class as it was declared which may lead to problems in older scripts
that rely on the previous behaviour (the class name was lowercased).
A possible solution is to search for <function>get_class</function> in
all your scripts and use <function>strtolower</function>.
<function>get_class</function> now returns the name of the class as it
was declared (case-sensitive) which may lead to problems in older scripts
that rely on the previous behaviour (the class name was always returned
lowercased). A possible solution is to search for
<function>get_class</function> in all your scripts and use
<function>strtolower</function>.

This case sensitivity change also applies to the
<link linkend="language.constants.predefined">magical predefined
constants</link> <constant>__CLASS__</constant>,
<constant>__METHOD__</constant>, and <constant>__FUNCTION__</constant>.
The values are returned exactly as they're declared (case-sensitive).
