To add an item to an array, do this:

 Help with Code Tags 
 PHP Syntax (Toggle Plain Text) 
$array_name[] = 'Value';
$array_name[] = 'Value';

Then to print out the entire array:

 Help with Code Tags 
 PHP Syntax (Toggle Plain Text) 
foreach($array_name as $key => $value) {
  echo $value . "<br />";
}
foreach($array_name as $key => $value) {
  echo $value . "<br />";
}

If that is not what you want then post an example of your code.

AJAX is not a programming language, scripting language or any other sort of language.
It is acheived by using JavaScript http functions.
So, AJAX = JavaScript.

Hey.

To add to an array from withing a recursive function, you need to either import a global variable into the function, or pass it as a reference parameter.

 Help with Code Tags 
 php Syntax (Toggle Plain Text) 
$myArray = array();
function setValue($value) {
  if($value < 100) {
    global $myArray;
    $myArray[] = $value;
    setValue($value+1);
  }
}
$myArray = array();
function setValue($value) {
  if($value < 100) {
    global $myArray;
    $myArray[] = $value;
    setValue($value+1);
  }
}

 Help with Code Tags 
 php Syntax (Toggle Plain Text) 
function setValue($value, &$myArray) {
  if($value < 100) {
    $myArray[] = $value;
    setValue($value+1);
  }
}
 
$myArray = array();
setValue(1, $myArray);
function setValue($value, &$myArray) {
  if($value < 100) {
    $myArray[] = $value;
    setValue($value+1);
  }
}

$myArray = array();
setValue(1, $myArray);

I would recommend the second option, because it gives you more control over how the variables are handled.

If this is not what you are talking about, please explain this better. Code examples are also very helpful.

Please do not ask for help in a PM. Use the forums.
And use [code] tags!
