OIK_Autoload::autoload() – Autoload a class if we know how to

Description

The fact that we have gotten here means that the class is not already loaded, so we need to load it … that's assuming we haven't already tried.

Usage

OIK_Autoload::autoload( $class );

Parameters

$class

( mixed ) required –

Returns

Source

  function autoload( $class )     {
    // Bail early if we've already tried to load this class.
    // This can happen if a plugin calls class_exists() multiple times
    // for the same class name but the class wasn't loaded.
        if (array_key_exists( $class, $this->tried_classes )) {
            $this->tried_classes[ $class ]++;
            return;
        }
        $this->tried_classes[ $class ] = 1;
