The manual page explains it pretty succinctly. I don't think you'll get
more simple than this, as there is obvious prerequisite knowledge
assumed (i.e. that you know what a simple variable is, etc)

Hi saeed,
Ash means this:
http://www.php.net/manual/en/language.types.array.php
See the examples in grey-colored boxes.
Arrays are just a collection of things. Similar to when you assign one
variable one value.. well with an array you assign many variables one value
each. But the reason you use an "array" is that instead of a bunch of separate
variables, you want those variables to be part of a collection.. i.e. all
those variables have something in common.. like for example you might use one
array to describe the parts of a car, and another array to describe all the
fruits in your kitchen.
You could do this: (all separate independent variables)
$part1 = 'spark plug';
$part2 = 'rear-view mirror';
$part3 = 'steering wheel';
etc.
$fruit1 = 'apple';
$fruit2 = 'banana';
$fruit3 = 'orange';
etc.
...but (depending on your application, and the logic you use), it might make
more sense to do something like this instead: (make arrays!)
(these, below, are arrays where the key is just a number which is automatically
assigned. You can also use another syntax (see the manual) to make arrays
where you generate your own custom keys, and those keys can be strings instead
of numbers.)
$arrParts = array('spark plug', 'rear-view mirror', 'steering wheel');
$arrFruits = array('apple', 'banana', 'orange');
To use the arrays, there are tons of functions:

I have a website that posts the most important news according to the number
of clicks to that news
the question is : what is the best way to prevent multiple clicks from the
same visitor?
