An array is a data structure that holds multiple values in one single variable at a time.
Let’s see you have a multiple items (a list of fruit names, for example), storing the fruit in single variables could look like this:
Now if you want to loop through the fruits and find a specific one? And what if you had lots of fruit ?
The solution is to create an array for this problem!. Let’s starts how to create an array?.

Types Of Array
There are three types of array in PHP which is given below and describing array one by one:
- Indexed array — An array with a numeric element.
- Associative array — An array where each element has its own specific value.
- Multidimensional array — An array containing one or more arrays within itself.
An indexed or numeric array holds each array value with a numeric index. There are two ways of creating an indexed array.
a. Simple Way: The index can be assigned automatically (index always starts at 0) .For an example see given below:
<?php // Define an indexed array $fruits= array("Apple", "Orange", "Papaya"); ?>
b. Indexes are Assigned Manually Way:
<?php $fruits = "Apple"; $fruits = "Orange"; $fruits = "Papaya"; ?>
