<title>Autoloading Objects</title>
<para>
Many developers writing object-oriented applications create
one PHP source file per-class definition. One of the biggest
annoyances is having to write a long list of needed includes
at the beginning of each script (one for each class).
</para>
<para>
In PHP 5, this is no longer necessary. You may define an
&link.autoload; function which is automatically
called in case you are trying to use a class which hasn't been
defined yet. By calling this function the scripting engine is given
a last chance to load the class before PHP fails with an error.
</para>
<para>
<example>
<title>Autoload example</title>
<para>
This example attempts to load the classes <literal>MyClass1</literal>
and <literal>MyClass2</literal> from the files <filename>MyClass1.php</filename>
and <filename>MyClass2.php</filename> respectively.
</para>
<programlisting role="php">
<![CDATA[
<?php
function __autoload($class_name)
{
include_once($class_name . 'php');
}
$obj = new MyClass1();
$obj2 = new MyClass2();
?>
