php coding help

suppose i have this code

$num = $_SESSION['count'];

$_SESSION['a'][$num] = $a_letter;

$_SESSION['b'][$num] = $b_letter;

$_SESSION['c'][$num] = $c_letter;

$_SESSION['d'][$num] = $d_letter;

$_SESSION['e'][$num] = $e_letter;

$_SESSION['f'][$num] = $f_letter;

if(!exists) {

$num = $_SESSION['count'];

$_SESSION['a'][$num] = $a_letter;

$_SESSION['b'][$num] = $b_letter;

$_SESSION['c'][$num] = $c_letter;

$_SESSION['d'][$num] = $d_letter;

$_SESSION['e'][$num] = $e_letter;

$_SESSION['f'][$num] = $f_letter;

}

else {

$num = $_SESSION['count'];

$_SESSION['a'][$num] = $a_letter;

$_SESSION['b'][$num] = $b_letter;

$_SESSION['c'][$num] = $c_letter;

$_SESSION['d'][$num] = $d_letter;

$_SESSION['e'][$num] = $e_letter;

$_SESSION['f'][$num] = $f_letter;

}

now i don't want those codes to copy paste repetitively, but instead I want to put a variable/value? so like

if (!exists)

{

$value

}

else {

$value

}

so I probably have to create a function in php then??

function list ()

{

$num = $_SESSION['count'];

$_SESSION['a'][$num] = $a_letter;

$_SESSION['b'][$num] = $b_letter;

$_SESSION['c'][$num] = $c_letter;

$_SESSION['d'][$num] = $d_letter;

$_SESSION['e'][$num] = $e_letter;

$_SESSION['f'][$num] = $f_letter;

}

so this becomes if(!exists) {$list} else {list} something like this?

how does this work please?
