I have a variable holding values separated by a comma (Implode), and I'm trying to get the total count of the values in that variable. However. count() is just returning 1.

I've tried converting the comma-separated values to a properly formatted array which still spits out1.

So here is the quick snippet where the sarray session is equal to value1,value2,value3:

$schools = $_SESSION['sarray'];
$result = count($schools);

You need to explode $schools into an actual array:

$schools = $_SESSION['sarray'];
$schools_array = explode(",", $schools);
$result = count($schools_array);

if you just need the count, and are 100% sure it's a clean comma separated list, you could also use substr_count() which may be marginally faster and, more importantly, easier on memory with very large sets of data:

$result = substr_count( $_SESSION['sarray'], ",") +1; 
 // add 1 if list is always a,b,c;

If there is sarray key set in session array, the count will return 1 for an empty string as well.

$session = array('sarray' => '');

$count = count(explode(',', $session['sarray']));

echo $count;

// => 1

So, if you want to count the number of items in the array, you will have to add an additional check for empty.

$session = array('sarray' => '');

$count = !empty($session['sarray']) ? count(explode(',', $session['sarray'])) : 0;

echo $count;

// => 0

Now, let's check if this works with items inside sarray.

$session = array('sarray' => 'foo, bar');

$count = !empty($session['sarray']) ? count(explode(',', $session['sarray'])) : 0;

echo $count;

// => 2
