Overloading has a different meaning in PHP. PHP does not support function overloading in the same manner as C++. However it possible to pass different number of arguments to a function using func_get_args.
function findSum() {
$sum = 0;
foreach (func_get_args() as $arg) {
$sum += $arg;
}
return $sum;
}
echo findSum(1, 2), '
'; //outputs 3
echo findSum(10, 2, 100), '
'; //outputs 112
echo findSum(10, 22, 0.5, 0.75, 12.50), '
'; //outputs 45.75
Overloading in PHP provides means to dynamically “create” properties and methods. These dynamic entities are processed via magic methods one can establish in a class for various action types.
The overloading methods are invoked when interacting with properties or methods that have not been declared or are not visible in the current scope.
Example for property overloading: __set() and __get()
Example for method overloading: __call()
