Question

I have the following php loop that takes an array that contains a set of arrays. I use this code to convert each array to a list, so I can manipulate the elements better.

This is my code…

while ($i<sizeof($my_array)){
    while(list($key,$val) = each($my_array[$i])){
      $j = $i+1;
        if ($key == "fruit"){
          $val = "ananas".$j;
          echo $val;
        }
     } 
 $i++;
 }

When I print the “search” array (print_r($my_array)), the values don’t change. I don’t understand why this doesn’t work as I had expected. Is there a solution to modify the $val without changing the loop structure and logic?

Use foreach with reference:

$i = 0;
foreach ( $my_array as $key => &$val ) {
    ++$i;
    if ($key == "fruit"){
        $val = "ananas" . $i;
        echo $val;
    }
}
