What's weird here is that one of the cases returns false and the other true. At least they should be returning the same value. ------------------------------------------------------------------------ [2020-06-26 08:10:13] qqqqqwwwww731 at gmail dot com Description: ------------ is_callable function behavior changed in php 7.4 Test script: --------------- <?php class A { public function serialize($v) { } public function func($v) { } } var_dump(is_callable(['A', 'serialize'])); var_dump(is_callable(['A', 'func'])); Expected result: ---------------- bool(true) bool(true) as in php before 7.4 Actual result: -------------- in php 7.4 we have bool(false) bool(true) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=79740&edit=1
