ceil() Strict Mode

ceil() doesn’t accept internal objects that can be converted to integer. This is the case for gmp and bcmath objects, as shown in the example. Since PHP 8.0, only integers and floats are allowed.

PHP code

<?php

$a = gmp_init(123456);

echo ceil($a);

?>

Before

123456

After

PHP Fatal error:  Uncaught TypeError: ceil(): Argument #1 ($num) must be of type int|float, GMP given

Fatal error: Uncaught TypeError: ceil(): Argument #1 ($num) must be of type int|float, GMP given

PHP version change

This behavior changed in 8.0
