i want to display like this : Tanggal 10 Agust - 15 Agust 2017

But its just display this : Tanggal -

How to display variable in my header ?

Answer 1

i think i have a solution. but its not the best solution. i cant echoing a variable in function, so im echoing contents of the variable. like this :

$this->Cell(20, 0.5, 'Tanggal '.substr($_GET['tgl1'],8).'etc...', 0, '0', "C", false);

Please comment if there is a better way
