Question

I have made the following code in a PHP file to list the content of a directory
and it works just fine

<?php

  $dir = opendir(getcwd());
  while (($file = readdir($dir)) !== false) {
    echo "filename : ". $file ."<br />";
  }
  closedir($dir);

?>

I want to make some changes in the output (string) result. I have tried a search and replace PHP code str_replace() but I have been unable to get it to work.

You can try the following

$dir = opendir(getcwd());
$max = 3 ;
$current = 0 ;
print('<table id="hor-minimalist-a" summary="Employee Pay Sheet"><tbody>');
while ( ($file = readdir($dir)) !== false ) {
    if ($file == "." || $file == "..") {
        continue;
    }
    $current++;
    if($current > $max)
        print("<tr>");
    printf("<td>%s</td>",$file);
    if($current >= $max)
    {
        print("</tr>");
        $current = 0;
    }
}
closedir($dir);
print('</tbody></table>');
