How to make Empty Array in PHP

To initialize an empty array in PHP assign [] or array() to the variable. Then you can, for example, push new values with array_push() function.

$array = [];

$array = array();

Example:

<?php

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

echo '<hr>';

array_push($array, 'foo');
print_r($array);

?>

Output:

Array ( )

Array ( [0] => foo )
