An array is a variable that holds a group of values.
Arrays are usually meant to store a collection of related
data elements, although this is not a necessity.
You access the individual elements by referring to their
index position within the array. The position is either specificied numerically
or by name.
$arr = array( key => value , ... )
- key may be an integer or string
- value may be any value
Example :
<?php
$arr = array("foo" => "bar", 12 => true);
echo $arr["foo"]; // bar
echo $arr[12]; // 1
?>
<?php
$arr = array("foo" => "bar", 12 => true);
echo $arr["foo"]; // bar
echo $arr[12]; // 1
?>
$arr = array("foo" => "bar", 12 => true);
echo $arr["foo"]; // bar
echo $arr[12]; // 1
?>
