How do I count comma-separated values in PHP?
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
$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
$session = array('sarray' => 'foo, bar'); $count = !empty($session['sarray']) ? count(explode(',', $session['sarray'])) : 0; echo $count; // => 2
Hope this helps.
