php check if a class exists

check if a class exists in php.

this can be used rather than assuming the class exists and then causing an error

You can run the class_exists function on the class before loading it with the following code

PHP

/* rather than this code to call the class */
$class = new class;

/* use the class exists function */
if class_exists("class") {
	$class = new class;
} else {
	// return an error message stating the class does not exist
}
