我可以使用两个名称定义相同的函数吗？

Question

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) { ......  }

Answer 1

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');
?>
