Re: How to Get the Sub Classes of a Parent Class

[Raymond Irving <xwisdom@xxxxxxxxx>]

This works if you know the name of the class. What I'm looking for is a way to get one of the sub classes and initialize it dynamically.

You may be able solve this with a simple class_exists() (pseudo-code ahead):

if(class_exists($var)) {
    $class = new $var;
} else {
    $class = new FourOhFour;
}
