Declaring a new array in php

In PHP, you can declare a new array using the following syntax:

$array_name = array();

Or, you can use the shorthand syntax:

$array_name = [];

Both of these methods will create a new empty array.

For example:

$fruits = array();
$fruits = [];

Both of these will create a new array called $fruits that is empty.

You can also declare an array with initial values using the following syntax:

$array_name = array('value1', 'value2',...);

Or, you can use the shorthand syntax:

$array_name = ['value1', 'value2',...];

For example:

$colors = array('red', 'green', 'blue');
$colors = ['red', 'green', 'blue'];

Both of these will create a new array called $colors with the values 'red', 'green', and 'blue'.

You can also use the array() function to create an array with initial values:

$numbers = array(1, 2, 3, 4, 5);

Note that in PHP, arrays are a type of data structure that can store multiple values, and are often used to store collections of data.
