Simple array question

[gokeeffe]

Hi

I have the following code that I am using to store values in an array, but is there anyway that I can count the number of items in the array without using the counter that I have, I mean is there any index style array command.

Also: Does any one know any good tutorials on php arrays.

Regards


// Set the counter
$_SESSION['counter']++;

// Set the array
$_SESSION['grind_array'][] = array(
'Interest' => $_SESSION['Interest'],
'Subject' => $_SESSION['Subject'],
'Level' => $_SESSION['Level'],
'counter' => $_SESSION['counter']
);

yeah there is, you just use the count function this counts the number of items there are in an array

example
<?php

$A = array("A","B","C");

echo count($A);

?>
