[RESOLVED] Array

[thekidscareya]

Is this a good piece of code or will it not work or is not efficient?

The user enters data into the database and $id is the unique id for the record.
The user has the option of entering multiple records into the table. I want to hold all of the IDs of the records that the user has entered into the database into a session.

<?php
$array = $_SESSION['graphics'];

$id = mysql_insert_id();
if(!is_array($array))
	{
	$array = array('$id');
	}else{
	$mode = end($array);
	foreach($array as $key=>$value)
		{
		if($value == $mode)
			{
			$last_key = $value;
			$new_key =  $last_key + 1;
			}
		}
	$array[$new_key] = $id;
	}

?>

Inefficient and incorrect (you didn't even try it, did you?).

if(isset($_SESSION['graphics']))
    $array = $_SESSION['graphics'];
if(!is_array($array))
    $array = array();

$id = mysql_insert_id();
if(!in_array($id, $array))
    $array[] = $id;

Obviously you'll want $_SESSION['graphics'] = $array later.

I modified it...with the loops in...Thanks a lot.

<?php
$array = $_SESSION['graphics'];
$id = mysql_insert_id();
if(!is_array($array))
	{
    $array = array($id);
	}else{
	if(!in_array($id, $array))
   		{
		$array[] = $id;  

		}
	}
?>
