  • So what's the output of your code? – u_mulder Dec 09 '14 at 08:31
  • the second part of a `for( ; ; )` statement is a test to continue, and it looks like your for loop might run forever. What does `$column++` do? When will $column become equal to 'AA' ? – RobP Dec 09 '14 at 08:32

Try PHP Range

<?php

        for($row=1; $row<=22; $row++){
            echo "<tr>";
            foreach (range('A', 'Z') as $char) { // Get A - Z as array 
              echo "FN{$row}{$char}";  //Concatenate as per your requirements 
             }
            echo "</tr>";
        }
    ?>

    Whilst correct, care to explain/add a few comments to your answer? The guy was struggling on this and an answer consisting of just code with no explanation is the minimal in usefulness – SubjectCurio Dec 09 '14 at 08:37

  for($row=1; $row<=22; $row++){
    echo "<tr>";
    for ($column='A'; $column<='Z'; $column++){ 
        echo "<td> FN".$row . $column." </td>";
    }   
    echo "</tr>";
  }

I think what you are missing is the range function in php, visit http://php.net/manual/en/function.range.php for detail information, I will leave you the example I built, regards.

<?php 

$array_alb = range('A', 'Z');
$array_num = range('1', '9');

echo '<pre>';
print_r($array_alb);
echo '</pre><pre>';
print_r($array_num);
echo '</pre>';

$prefix = 'FN';
$result  = array();

foreach ($array_num as $num) 
{
    foreach($array_alb as $letter)
    {
        $result[] = $prefix.$num.$letter;
    }
}

echo '<pre>';
print_r($result);
echo '<pre>';
?>

  • Php is stateless script, so you will need to store somehow what other user have used of the $result array i gave you, then when a new user comes, check wich are the availables codes and used then, summarizing, store result array in a database with a flag field called 'used' may be and each time a user picks up item check for the min key available wich flag is not used and assign to it and mark it in your DB with the flag. remember php is stateless, you store states info in DB or use SESSION, or COOKIE or FILES or YIELD generators if you are using 5.5 to overcome that fact, regards – DiegoCoderPlus Dec 09 '14 at 10:30
