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