7. PHP 6?
8. PHP 7 is snel
9. Loosely typed vs Strict types declare(strict_types=1);
10. Scalar type hints & Return type declarations function add(int $a, int $b): int{ return $a + $b; }
11. <?php /** * Scalar type declarations */ //declare(strict_types=1); function add(int $a, int $b) { return $a + $b; } var_dump(add(1,2)); var_dump(add("1","2"));
12. <?php /** * Return type declarations */ //declare(strict_types=1); function add(int $a, int $b): int{ return (string)($a + $b); } var_dump(add(1,2));
13. <?php /** * Anonymous classes */ $foo = new class { public function foo() { return "bar"; } }; var_dump($foo,$foo->foo());
14. Generators Sinds PHP 5.5 Iterator shorthand Minder overhead
15. Yield
16. <?php function gen_one_to_three() { for ($i = 1; $i <= 3; $i++) { yield $i; } } $generator = gen_one_to_three(); foreach ($generator as $value) { echo "$value\n"; }
17. <?php /** * Generator delegation */ function gen() { yield 1; yield 2; yield from gen2(); } function gen2() { yield 3; yield 4; } foreach (gen() as $val) { echo $val, PHP_EOL; }
18. <?php /** * Space ship operator */ $array = [ "1 <=> 1" => 1 <=> 1, "1 <=> 2" =>1 <=> 2, "2 <=> 1" => 2 <=> 1 ]; var_dump($array); array(3) { '1 <=> 1' => int(0) '1 <=> 2' => int(-1) '2 <=> 1' => int(1) } Output
19. <?php /** * Throwable interface */ //Error as Throwable try { sqdf(); } catch (Throwable $t) { echo "Throwable: ".$t->getMessage().PHP_EOL; } //Exception as Throwable try { throw new Exception("Bla"); } catch (Throwable $t) { echo "Throwable: ".$t->getMessage().PHP_EOL; } //Error try { sqdf(); } catch (Error $e) { echo "Error: ".$e->getMessage().PHP_EOL; } catch (Exception $e) { echo "Exception: ".$e->getMessage().PHP_EOL; }
20. <?php /** * Throwable interface */ //Exception try { throw new Exception("Bla"); } catch (Error $e) { echo "Error: ".$e->getMessage().PHP_EOL; } catch (Exception $e) { echo "Exception: ".$e->getMessage().PHP_EOL; } //Type error try { function add(int $a, int $b):int { return $a + $b; } echo add(array(), array()); } catch (TypeError $t) { echo "Type error: ".$t->getMessage().PHP_EOL; }
