No tricks. integers may always be coerced to floats, even with strict_types=1. This is covered in the original RFC but not in the online docs for return types. https://wiki.php.net/rfc/scalar_type_hints_v5#behaviour_of_strict_type_checks https://www.php.net/manual/en/functions.returning-values.php#functions.returning-values.type-declaration Note that section does mention return typing works like argument typing does, and their docs do mention the int->float exception. https://www.php.net/manual/en/functions.arguments.php#functions.arguments.type-declaration.strict Previous Comments: ------------------------------------------------------------------------ [2020-06-12 01:28:18] cxlblm at gmail dot com Description: ------------ We can see https://3v4l.org/tmcO4 What is the type of numeric constant Test script: --------------- <?php declare(strict_types=1); function testFloat(): float { return 1; } var_dump(is_float(testFloat())); var_dump(is_float(1)); function testInteger(): int { return 1; } var_dump(is_int(testInteger())); var_dump(is_int(1)); ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=79694&edit=1
