Arrays are variables that are capable of holding multiple values, a group of data. These are heavily used in development, so in this beginner’s guide I’ll show how to declare, access and manipulate arrays in PHP.
PHP supports indexed, associative, and multidimensional array types.
Declaring Arrays in PHP
