Arrays

We talk about what variables are in previus tutorial today we will learn what an array is and what we can do with it.



An array is a variable that can hold more than one value at a time, think that an array is a list it has a name, index and value.

to declare an array is very easy in php and can save you time:
While holding simple information like name and surname is ok but if you want to retrieve information from database then you have to use an array.

Declare of an array:

$phones = array("nokia", "sony erricson", "htc");

Alternative:

$phones[0] = "nokia";
$phones[1] = "sony erricson";
$phones[2] = "htc";

Retrieve values:

<?php

echo $phones[0];
echo "</br>";
echo $phones[1];

echo "</br>";
echo $phones[2];
echo "</br>";

?>
