unpacking an array of arguments in php
In certain scenarios, you might consider using unpacking
, which is possible in php, is a similar way to python:
list($min, $max) = [3, 6];
range($min, $max);
This is how I have arrived to this answer at least.
Google search: PHP argument unpacking
You can use call_user_func_array()
to achieve that:
call_user_func_array("range", $args);
to use your example.
In php5.6
Argument unpacking via ...
(splat operator) has been added. Using it, you can get rid of call_user_func_array()
for this simpler alternative. For example having a function:
function add($a, $b){
return $a + $b;
}
With your array $list = [4, 6];
(after php5.5 you can declare arrays in this way).
You can call your function with ...
:
echo add(...$list);
You should use the call_user_func_array
call_user_func_array(array(CLASS, METHOD), array(arg1, arg2, ....))
