Array Has No Absolute Name¶
Classes may be used as type, with an optional leading \. This is not the case for scalar types, such as int or string, but it was the case for array. In PHP 8.5, it is now homogenized.
PHP code¶
<?php
function foo(\array $x = []) {}
?>
Before¶
PHP Fatal error: Cannot use array as default value for parameter $x of type array in /codes/absoluteArrayName.php on line 3
Fatal error: Cannot use array as default value for parameter $x of type array in /codes/absoluteArrayName.php on line 3
After¶
PHP Fatal error: Cannot use array as a type name as it is reserved in /codes/absoluteArrayName.php on line 3
Stack trace:
#0 {main}
Fatal error: Cannot use array as a type name as it is reserved in /codes/absoluteArrayName.php on line 3
Stack trace:
#0 {main}
PHP version change¶
This behavior changed in 8.5
