Difference between array,list and map

The difference between array and list is that you can use array with keys which are not varibles, list assigns the array values to list vars, array_map applies the function to the array elements. Take a look at the examples at manual pages:

http://www.php.net/manual/en/function.list.php
http://php.net/manual/en/function.array-map.php

Thanks Genius but I am still confused as to when to use one over the other.

The most cases - you use array, basicaly it depends on what you want to do.
Let's make examples:

<?php

// lets's make an array
$a = array(1, 2, 3);

// show me the array
print_r($a);

// let's make a list
list($first, $second, $third) = $a;

// list is like an array keys, but you can acces them with 
// variable name like $first, not with $a[0]
echo $first;

?>

Select allOpen in new window

   

Or more complete one:

<?php


function addone($n)
{
    return($n + 1);
}



// lets's make an array
$a = array(1, 2, 3);

// show me the array
print_r($a);

// let's make a list
list($first, $second, $third) = $a;

// list is like an array keys, but you can acces them with 
// variable name like $first, not with $a[0]
echo $first;

$aa = array_map("addone", $a);
print_r($aa);
?>

Select allOpen in new window
