Try getting them from their ASCII Code like this :

<?php
$arr = str_split('12345');
$str = chr($arr[0]+64);
echo ("str=".$str."\n");
?>

By using base_convert, I made this:

$arr = str_split('12345');

foreach($arr as $something){
    if($something==1){
        $value=$something*10;
    }else{
        $value++;
    }
    echo base_convert($value, 10, 36);
}

Might not be the best solution but it is a solution. I'll explain what I did here.

In the docs it says:

Digits in numbers with a base higher than 10 will be represented with the letters a-z, with a meaning 10, b meaning 11 and z meaning 35

So I just made sure 1=10,2=11,3=12,4=13,5=14 etc...

Result: abcde

Easiest solution I can think of right now: 

$arr = str_split('12345');
$arr2 = str_split('abcdefghijklmnopqrstuvwxyz');

foreach($arr as &$digit)
    $digit = $arr2[$digit-1];

note that $digit is passed to the loop by reference using a & symbol. That means that when you manipulate $digit, the respective array entry in $arr will be changed as well.
