    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.');
                }
            }
        }
    ?>
