A note to visus at portsonline dot net or anyone else trying to dynamically choose a parent class:
A much beter method than creating a second file is to use eval to create an intermediate class.
Compare the following to the solution from visus at portsonline dot net:
<?php
$databaseSystem = "mysql";
class mysql
{
function show()
{
print("bar");
}
}
eval('class intermediate extends ' . $databaseSystem . ' {}');
class ActiveRecord extends intermediate
{
function ActiveRecord()
{
print("foo");
}
}
$instance = new ActiveRecord;
$instance->show();
?>
