How to create a new array in php

Arrays are a common data type for PHP developers, they allow multiple values to be stored in a single variable. In PHP, there are several ways to create and initialize arrays.

Create an empty array

To create an empty array, you can use the following syntax:

$myArray = array();

The above code creates an empty array named$myArrayempty array.

Create a non-empty array

To create an array containing a set of values, you can use the following syntax:

$myArray = array('value1', 'value2', 'value3');

Alternatively, use the following syntax to create an associative array:

$myArray = array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3');

In the above example, the$myArrayvariable contains a set of string values or associated key-value pairs. You can use the same syntax and pass any data type to the array (e.g. integer, float, boolean, object, etc.).

If you already know the size of the array, you can use the following syntax to create an array with a specified size and default value:

$myArray = array_fill(0, 10, 'default_value');

The above code creates an array named$myArrayan array with 10 elements and initialize each element to the default valuedefault_value.

Summary

In PHP, creating an array is very easy. You can use an empty array to create an empty array, or you can use values or associated key-value pairs to create a non-empty array. If you know the size of the array, thearray_fill()function conveniently provides you with a way to create an array of a specific size and default value. Whenever you create an array, it is important to use the appropriate methods to help ensure that your code is correct and readable.
