PHP list() function is not work. List return value variables values is null why?-CodePudding

$transaction value:

[
'date'        => $date,
'check' => $check,
'description' => $description,
'amount'      => $amount,
];

My create function:

public function create(array $transaction) : int {
        [$date, $check, $description, $amount] = $transaction;
        echo '<pre>';
        var_dump($date, $check, $description, $amount);
        print_r($transaction);

        die();
    }

result:

Warning: Undefined array key 0 in /var/www/app/models/Transaction.php on line 11

Warning: Undefined array key 1 in /var/www/app/models/Transaction.php on line 11

Warning: Undefined array key 2 in /var/www/app/models/Transaction.php on line 11

Warning: Undefined array key 3 in /var/www/app/models/Transaction.php on line 11

    [date] => 01/04/2021
    [check] => 7777
    [description] => Transaction 1
    [amount] => 150.43
)

** Why date, check, description and amount variables is null? ** ** How can i solve this problem, my variables are coming empty. **

CodePudding user response：

If you assign to an array, then your source must have numeric keys, starting with 0, then 1, then 2, etc.

You could use:

[$date, $check, $description, $amount] = array_values($transaction);

but make sure the source items are always in the correct order.
