counting total in an array

[ahmed24]

can anyone please tell me how i can count the total in an array?

my array is called $courses and it produces output like this:

Array
(

[1] => Array
(
[FIRST_NAME] => Bob
[LAST_NAME] => Smith
)

[2] => Array
(
[FIRST_NAME] => John
[LAST_NAME] => Townsend
)

)

in the example above there are a total of 2 results but this changes and i want to know how i can determine the total?

thanks

There are two methods that will fit your example.

1.) Use the array length as the "total" since your array is already set up consistently this way.

<?
$total = count($courses);
//OR
$total = sizeof($courses);
?>

2.) The second method is to loop through the whole array.

<?
$total = 0;
foreach(array_keys($courses) as $key){
$total+=1;
}
?>
