php, this array works in global but failed while putting inside class

I have following array, this works fine If i put in global and access the php with CLI but it gives following error while putting this same array in class.

'printer_1' => array(
    't_char_set' => 'ch-latin-2',

    'find' => array('Ä',      'Ö',      'Ü',      'ä',      'ö',      'ü' ,
                    'à',      'â',      'ç',      'é',      'è',      'ê' ,
                    'ë',      'ï',      'î',      'ì',      'ô',      'ò'),

    'repl' => array(chr(142), chr(153), chr(154), chr(132), chr(148), chr(129),
                    chr(133), chr(131), chr(135), chr(130), chr(138), chr(136),
                    chr(137), chr(139), chr(140), chr(141), chr(147), chr(149))
);                                  
Copy code

while putting this as a variable in class it's gives following error

PHP Parse error: syntax error, unexpected '(', expecting ')' in xxx.php on line 6

any clue ?

edit: Here is the full class (I have removed the other functions to minimize the content.)

<?php
  $K_printer = array(


     'TM1' => array(

  class KP{


       private $width;                 // output width (characters)

        $this -> LoadSetup($printer_setup);
     }

     //removed other functions...

     //
     // Load Printer Setup

     function LoadSetup($printer = false){
        global $K_printer; 

        if(!isset($K_printer[$printer])){
           $this -> error('Unknown printer setup.');
           return false;
        }

        $this -> width = $K_printer[$printer]['width'];
        $this -> translate = $K_printer[$printer]['translate'];
        $this -> printer_char_set = $K_printer[$printer]['p_char_set'];
        return true;
     }


  }

?>

This works fine from PHP cli with following say t1.php file

      $ep = new KP('TM1');
Copy code

but I i simply include this file in other class function "require('t1.php')", the $K_printer is passed as NULL in LoadSetup function so it's throwing error. (I diderror_log(print_r($K_printer, true)); to capture this in error.log file of apache2.

really trying to find what is wrong since last night, finally wrote on stackoverflow to seek some expert advice.
