An array is used to store multiple values, generally of same type, in a single variable.
For example if you have a list of festivals that you want to store together, or may be a list of stationary items, or list of colors, then you can either keep them in separate variables, but then you will have to create a lot of variables and they won't be related to each other.
In such case, PHP arrays are used. Arrays can store multiple values together in a single variable and we can traverse all the values stored in the array using the
We can create an array in PHP using the
<?php /* this function takes multiple values separated by comma as input to create an aray */ array(); ?>
In PHP there are 3 types of array:
Let's take a simple example for an array to help you understand how an array is created.
<?php /* a simple array with car names */ $lamborghinis = array("Urus", "Huracan", "Aventador"); ?>
To access the data stored in an array, we can either use the index numbers or we can use a
foreach loop to traverse the array elements.
Index number for array elements starts from
0, i.e the first element is at the position
0, the second element at position
1 and so on...
<?php /* a simple array with Lamborghini car names */ $lamborghinis = array("Urus", "Huracan", "Aventador"); // print the first car name echo $lamborghinis; echo "Urus is the latest Super SUV by Lamborghini"; ?>
Urus Urus is the latest Super SUV by Lamborghini
Here are a few advantages of using array in our program/script:
