From PHP7 onwards, a single use statement can be used to import Classes, functions and constants from same namespace instead of multiple use statements.
<?php // Before PHP 7 use com\howcodex\ClassA; use com\howcodex\ClassB; use com\howcodex\ClassC as C; use function com\howcodex\fn_a; use function com\howcodex\fn_b; use function com\howcodex\fn_c; use const com\howcodex\ConstA; use const com\howcodex\ConstB; use const com\howcodex\ConstC; // PHP 7+ code use com\howcodex\{ClassA, ClassB, ClassC as C}; use function com\howcodex\{fn_a, fn_b, fn_c}; use const com\howcodex\{ConstA, ConstB, ConstC}; ?>
