PHP ArgumentCountError服务器是否特定？

Question

I am facing very weird problem since last two days, I have two different servers one is windows(php v5.3) and second is linux(php v7.1 ngnix). I have a project(written by someone) which is already running on windows server, now I have to move this project on linux server (with no code change). My issue, There is a login function -

Function userAuthentication($username,$password,$locationId,$url,$source)
{
....
}

And It is calling as (On windows server)

userAuthentication($username, $password,'',$url) ;

I know parameters are mismatched in this case but as I tested, this code is actually giving me result and working fine on windows but that same code is giving me obvious error on Linux server-

ArgumentCountError: Too few arguments to function Authentication::userAuthentication(), 4 passed in

It can be resolve by changing that code but I don't want (can to be many function with same error). I already googled but not found anything. I am very curious to know Why this is not happening on windows. Is that ArgumentCountError server specific or windows server not taking it as critical as linux, or php version issue or any other config.? what I suppose to fix to resolve this issue.?

Anyone have any idea about that please help me out, Thanks

Answer 1

The difference isn't in the Environment (windows vs. linux) rather the PHP version.

As you can see in the migration from PHP 7.0 to 7.1 (link: http://php.net/manual/en/migration71.incompatible.php)

Throw on passing too few function arguments

Previously, a warning would be emitted for invoking user-defined functions with too few arguments. Now, this warning has been promoted to an Error exception. This change only applies to user-defined functions, not internal functions. For example:

<?php
function test($param){}
test();

The above example will output something similar to:

Fatal error: Uncaught ArgumentCountError: Too few arguments to function test(), 0 passed in %s on line %d and exactly 1 expected in %s:%d

How to solve it?

You'll have to define all the parameters in the function. It might be "uncomfortable" but it's a better practice as a developer. Don't be lazy regarding this issue.
