How to get Array Count on Javascript and PHP

Being a web developer, learning array is essential. You can use them as a list of values, a collection, stack and more. Array is usually use in Objective Oriented Programming but it is also helpful even in a simple program.

Ok, since array is a collection we need to know the number of item / values or shall we say the length of an array. Getting its length is useful in doing a loop statement.

Getting array length / count on PHP


<?php
$yourArray = array('value1, 'value2, 'value3');
echo count($yourArray);
?>
PHP use the count() function to get the array length.

Getting Array length on Javascript

<script language="javascript" type="text/javascript">
var yourArray = new Array('value1', 'value2', 'value3');
document.write(yourArray.length);
</script>
