Can I define the same function with two names?

I want to define one function, but with two different names. I can achieve that such:

function my1($a, $b) { ......  }
function my2($a, $b) { my1($a,$b); }

but I am interested, if there is a shorter way, like:

function my1 & my2 ($a, $b) { ......  }

You can make a recursive function instead of creating two same function. For example:

function my1($a, $b, $is_recursive = false) {
    ...

    if ($is_recursive) {
        my1($a, $b, false);
    }
}

Yes! for that you need to use anonymous functions. One variable hold your function and another variable refer to same variable.

<?php
// Define function
$say_hello_1 = function ()
{
  echo "Hello";
};

// Refer to same function with different name
$say_hello_2 = $say_hello_1;

// Call to both of them
$say_hello_2();
$say_hello_1();

Both of call represent same function and print Hello twice.

try anonymous functions. It allows you to call the same function but with different names. like so

<?php
$function_1 = $function_2 = function($a,$b){ //The anonymous function is assigned names $function_1 & $function_2.
    echo $a.' - '.$b;
};

$function_1('a','b');

$function_2('1','2');
?>
