No min() On Empty Array¶
min() does not accept an empty array as argument. In that case, it used to return NULL, but NULL is also a valid return value, and it is not possible to differentiate between the NULL of an empty array and the NULL that is really a minimum value.
PHP code¶
<?php
min([]);
?>
Before¶
PHP Warning: min(): Array must contain at least one element
Warning: min(): Array must contain at least one element
After¶
PHP Fatal error: Uncaught ValueError: min(): Argument #1 ($value) must contain at least one element in codes/minOnEmpty.php:3
Fatal error: Uncaught ValueError: min(): Argument #1 ($value) must contain at least one element in codes/minOnEmpty.php:3
PHP version change¶
This behavior changed in 8.0
