Answer 1

How the goal is to compare the value of letra with the current array item str(i).

One way to do this with php is to create a template through an array where the keys are the letters (A-Z) and the values are 1-26 who performed this task is array_merge() that takes two arguments the first are the keys of the new array and the second the values. After that just check if there is the Indice $letra in $str positive case writes novidade- followed by the value.

$arr = array('01A', '01B', '01C', '01Z');
$titulo = 'novidade';
$str =  array_combine(range('A', 'Z'), range(1,26));


foreach($arr as $v){
    $letra = substr($v, -1, 1);
    if(isset($str[$letra])){
        echo 'novidade-'.$str[$letra] .'<br>';
    }   
}

Exit:

novidade-1
novidade-2
novidade-3
novidade-26

Answer 2

Look what I understood from the question, do you want the letter to correspond to an index? If it is this see if this solution meets you:

 <?php
  $letras = range('A', 'Z');
  $cod = '10F';
  $titulo = "Novidade";

  $letra = substr($cod,-1);
  $index = array_search($letra, $letras)+1;

  print "$titulo-$index\n";

Sure I extrapolated a little bit of your result, but the end result would be this:

Novidade-6
