Bug Type: Bug
Bug description:Comparing int/string with max() always returns string
Description:
------------
The documentation of max() says:
"Values of different types will be compared using the standard
comparison rules. For instance, a non-numeric string will be compared to
an int as though it were 0."
Using PHP 8.0 and above, I'm observing a deviating behavior, that is,
the string value is returned instead. Parameter order does not matter.
If this is the intended behavior, the documentation should be updated /
the cited snippet should be removed.
Up to PHP 7.4.13, the observed result matches the documentation.
Test script:
---------------
<?php
var_dump(max("A", PHP_INT_MAX));
var_dump(max(PHP_INT_MAX, "A"));
Expected result:
----------------
int(1)
int(1)
Actual result:
--------------
string(1) "A"
string(1) "A"
