IF function in PHP-CodePudding

Why this is not working?

<?php 
if (count($payment_method) > 0 
    && !(count($payment_method) == 1 
    && implode('',$payment_method) == 'PayPal'));
?>

Error is here

Warning: count(): Parameter must be an array or an object that implements Countable in C:\xampp\htdocs\signup\templates\default\html\subscription.php on line 239

CodePudding user response：

Change your condition to include a test on array type

<?php 
if (is_array($payment_method)
    && count($payment_method) > 0 
    && !(count($payment_method) == 1 && current($payment_method) == 'PayPal')
);
?>

CodePudding user response：

It means that your $payment_method variable has to be an array or an object that looks something like:

class MyClass implements Countable {
    public count(): int {}
}

You can simply learn what value it has by using the var_dump($payment_method) function and keep on.
