Array & strtok

[help_needed]

Hi,

I was hoping someone could help me with the following.

I have this.

$string[] = "a, 10, one";
$string[] = "b, 20, two";

if ($_POST[input] == "a")
{
$item[0] = "a";
$item[1] = "10";
$item[2] = "one";
}

I hope you understand what I'm trying to accomplish.
I have several strings in identical format. id, quantity, name.

If a visitor enters a specific id, I'd like to be able to get all the information associated with that particular id in the format i have above.

I got this from php.net

<?
$string= "a, 10, one";

$tok = strtok($string,",");
	while ($tok) 
	{

                            echo "Word=$tok<br>";
		$tok = strtok(",");
}
echo $string;
?>

Have a look at [man]explode[/man] and [man]join[/man]

$str = "a, 10, one";

$item = explode (',' , $str)

gives  $item[0] = "a"; 
          $item[1] = "10"; 
          $item[2] = "one"; 

and back again

$str = join( ', ' , $item)   gives "a, 10, one"
