php - Syntax error when trying to put together constant and string -

this question has answer here:

• php parse/syntax errors; , how solve them? 12 answers

normally wouldn't post syntax errors here, case bit suspicious me. trying put constant string. works fine on localhost, when push project on web server, 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 line 

has different php versions? (5.5 on webserver, 7.0 localhost)

update

some updates in code:

class someclass {      private $somepath = root . "some/path"; //synax error in line      ... } 

you can't use str_replace() nor function when defining contant. try:

define("root", $_server["script_filename"]); $somepath = str_replace("index.php", "", root) . "some/path"; 

please refer php manual:

in php 5, value must scalar value (integer, float, string, boolean, or null). in php 7, array values accepted.
