Google won't help me; I want to pass an array as an argument list to a function.
I can't edit the function itself, so I can't pass an array. It expects this:
function doSomething($arg1, $arg2, [$arg3...]) {
//code...
}
And I have this:
$args = array('arg1', 'arg2', 'arg3'...);
How can I pass them anyway?
You can use call_user_func_array.
Use like:
$array = array(1, 2, 3);
call_user_func_array("myfunc", $array);
function myfunc($a, $b, $c) {
var_dump($a, $b, $c); // 1 2 3
}
$array = array(2, 3);
$first = 1;
call_user_func_array("myfunc", array_merge(arary($first), $array));
function myfunc($a, $b, $c) {
var_dump($a, $b, $c); // 1 2 3
}
In case of an object instance your callback should look like:
array($obj, "someFunc")
so:
call_user_func_array(array($obj, "someFunc"), $array);
array_merge magic to get the arguments you want.
