problem: join 2 strings in a class

[abahaedini]

hi thereI have a constants as name: FIXED_VAR,I defined it in the config.php file! (another file) define("FIXED_VAR", ""pre_); now, I define a class:

class admins extends users{var $table_name=FIXED_VAR."admins";function ...}

but I get an error:

Parse error: syntax error, unexpected '.', expecting ',' or ';' in F:\server\www\samaschools\score\core\classes\admins.php on line 3

in line 3 these code works:var $table_name="admins";var $table_name=FIXED_VAR; but these code dosent work:var $table_name=FIXED_VAR."admins";var $table_name=$_session['type']; what's wrong? is there any solutions?

You can't operate when declaring a class property. That's what the constructor is for. The constructor is written like this:

function __construct() {    $this->table_name = FIXED_VAR . 'admins';}
