What are the two types of php arrays?

What is an array?

Array is a special variable that can save more than one value at the same time. (Recommended learning:PHP Programming from Beginner to Master)

If you have a list of items (such as a list of car brands), storing these brand names in a single variable is like this:

$cars1="porsche"; $cars2="BMW"; $cars3="Volvo";

However, what if you want to iterate through the variables and find a specific value? Or what if you need to store 300 car makes instead of 3?

The solution is to create an array!

Arrays can store many values in a single variable name, and you can access a value by referencing an index number.

PHP Index Array

There are two ways to create an index array:

The index is automatically assigned (index starts from 0):

$cars=array("porsche","BMW","Volvo");

PHP Associative Arrays

An associative array is an array using specified keys that you assign to the array.

There are two ways to create associative arrays:

$age=array("Bill"=>"35","Steve"=>"37","Elon"=>"43");
