You cannot overload PHP functions. Function signatures are based only on their names and do not include argument lists, so you cannot have two functions with the same name. Class method overloading is different in PHP than in many other languages. PHP uses the same word but it describes a different pattern.


You can, however, declare a variadic function that takes in a variable number of arguments. You would use func_num_args() and func_get_arg() to get the arguments passed, and use them normally.


For example:


// *******************************************

function myFunc() {

for ($i = 0; $i < func_num_args(); $i++) {

printf("Argument %d: %s\n", $i, func_get_arg($i));

}

}


/*

Argument 0: a

Argument 1: 2

Argument 2: 3.5

*/

myFunc('a', 2, 3.5);

// ********************************************
