php function help?

[nochlux]

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 come up with a function - 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;

 

}

 

$value = function list();

 

if (!exists)

 

{

$value

 

}

 

 

else {

 

$value

 

}

 

How does this work please?

I can't follow what you are doing. Looks to me like you do the same thing in your if{} and your else{} Then you create a function that returns nothing. Sorry I can not help more.

...You're doing the exact same thing in not just three places but in both branches of an if. It's not a problem of code reuse but of code redundancy.

Do it on your frame layout, so it is on all pages by default.
