What is an Array
An array stores multiple values in one single variable:
Example:
$fruits = array("Apple", "Orange", "Banana");
What is PHP Arrays?
Arrays are complex variables that allow us to store more than one value or a group of values under a single variable name. Let's suppose you want to store fruits in your PHP script. Storing the fruits one by one in a variable could look something like this:
<?php
$fruit1 = "Apple";
$fruit2 = "Orange";
$fruit3 = "Banana";
?>
In PHP, the array() function is used to create an array:
array();
In PHP, there are three types of arrays:
- Indexed or Numeric Arrays: An array with a numeric index where values are stored linearly.
- Associative Arrays: An array with a string index where instead of linear storage, each value can be assigned a specific key.
- Multidimensional Arrays: An array which contains single or multiple array within it and can be accessed via multiple indices.
