This should be pretty simple but all the searches I do turn up looping through an associative array. I’ve created an array in a Session contining links clicked so that when someone returns from a thank you page the links they clicked on can be disabled. When you go from the page with links to the thank you page I add it to the Session array:

//add $linkVisted array to the session  
$\_SESSION[‘linkVisted’] = $linkVisted;

//add the next number to the array  
array\_push($linkVisted,$link);

This works and returns the following output when I return to the links page:

Array ( [linkVisted] =\> Array ( [0] =\> 3 [1] =\> 3 [2] =\> 1 [3] =\> 1 [4] =\> 8 [5] =\> 9 ) )

Now, how do I loop through this array to compare each link’s number with these numbers? When I try this I get an array length of 1 - because there is only one array - so how do get the number of elements (9 here) and loop through them?

for ($i = 1; $i \< count($linkVisted); ++$i) {  
echo $linkVisted[$i];  
}

Thanks!
