An array in PHP is actually an ordered map. A map is a type that associates values to keys.
The array stores one or more similar type of values in a single value.
array(
key => value,
key2 => value2,
key3 => value3,
...
)
Each map is a key-value pair.
The key as also known as array index.
The key can either be an integer or a string.
The value can be of any type.
<?php
$fruits = array(0=>"Apple", 1=>"Orange", 2=>"Pear");
var_dump($fruits);
echo "<br>";
$colors = array(
"Red" => "#F00",
"Green" => "#0F0",
"Blue" => "#00F"
);
var_dump($colors);
?>
