Syntax error when trying to put together constant and string

Question

Normally i wouldn't post syntax errors here, but this case is a bit suspicious to me. I was trying to put together a constant with a string. I works fine on localhost, but when i push my project on my web server, it tells me:

Parse error: syntax error, unexpected '.', expecting ',' or ';' in xxx on line xxx

Code:

define("ROOT", str_replace("index.php", "", $_SERVER["SCRIPT_FILENAME"]));

and

$somePath = ROOT . "some/path"; //Synax error in this line

Has this something to do with different PHP versions? (5.5 on webserver, 7.0 localhost)

Update

Some updates in the code:

class SomeClass {

    private $somePath = ROOT . "some/path"; //Synax error in this line

    ...
}

Can't reproduce the error. Please make sure you show us the full, real and relevant code here. Also read and provide us with a [mcve]. — Rizier123, Sep 07 '16 at 12:01

You can't have an expression in an instance property definition iirc. (At least in your PHP version). Put it in the constructor. — Jonnix, Sep 07 '16 at 12:07

You can't use str_replace() nor any function when defining a contant. Try:

define("ROOT", $_SERVER["SCRIPT_FILENAME"]);
$somePath = str_replace("index.php", "", ROOT) . "some/path";

Please refer to PHP Manual:

In PHP 5, value must be a scalar value (integer, float, string, boolean, or NULL). In PHP 7, array values are also accepted.
