Bug description:Null coalesce operator example has if/else wrong way round
Description:
------------
The Null coalesce operator has an incorrect example. See
https://php.net/manual/en/language.operators.comparison.php#language.operators.comparison.coalesce
<?php
// Example usage for: Null Coalesce Operator
$action = $_POST['action'] ?? 'default';
// The above is identical to this if/else statement
if (isset($_POST['action'])) {
$action = 'default';
} else {
$action = $_POST['action'];
}
?>
Should actually be:
<?php
// Example usage for: Null Coalesce Operator
$action = $_POST['action'] ?? 'default';
// The above is identical to this if/else statement
if (isset($_POST['action'])) {
$action = $_POST['action'];
} else {
$action = 'default';
}
?>
