Already Exists

Dysan

Using the following code, how do I check if the array contains a particular id, and if it does, display the following message, else add the id to the array?

Message "ID Already Exists!"

<?php

session_start();

$_SESSION['ids'][] = $_GET['id'];
$array = $_SESSION['ids'];

print_r($array);

?>

See how nice code formated with the php tags looks?

<?php
session_start();
$_SESSION['ids'][] = $_GET['id'];
$array = $_SESSION['ids'];

if(array_key_exists($_GET['id'], $array))
{
echo "ID Already Exists!";
}
else
$array[$_GET['id']] = 'some value';
?>

How do I search the array for particular data e.g. "Dave" then delete "Dave from the array

cahva

$key = array_search('Dave', $array);
if ($key !== false)
    unset($array[$key]);

.. is that what you meant?

just so you are clear on it, array_key_exist() checks for a key in an array while array_search() search for a value in that array.
