How to use array function

PHP array() function is used to create arrays.

php array() function syntax

Function: Generate an array

Syntax:

Index array:

array(value1,value2,value3,etc.);

Associative array:

array(key=>value,key=>value,key=>value,etc.);

Parameters:

key specifies the key name (numeric value or string).

value specifies the key value.

Description: array() creates an array with keys and values. If the key is omitted when specifying the array, an integer key is generated that starts at 0 and increments by 1. To create an associative array with array(), use => to separate the keys and values. To create an empty array, pass no arguments to array().
