Why is function overloading not supported in PHP?

Function overloading is not supported in PHP because PHP does not allow multiple functions with the same name but different parameter lists. To achieve similar functionality, you can use default parameter values or variable-length argument lists. This allows you to create a single function that can handle different numbers of arguments. Example: 

function myFunction($arg1, $arg2 = null, $arg3 = null) {
    // Function logic here
}

myFunction(1);
myFunction(1, 2);
myFunction(1, 2, 3);
