A typical use for this exception, is in conjunction with the is_callable() function.

Direct known subclasses:
BadMethodCallException

So BadMethodCallException can be used in case the subject function is or should be a part of class / object - it's use defines the case more precisely.

For example :
<?php
class Image
    {
    public function __construct()
        {
        if (!extension_loaded('gd')) 
            {
            throw new BadFunctionCallException('GD extension is not loaded.');
            }
        }
    }
?>
