Talks #75 - PHP 7

PHP7 it's almost ready. Let's do a quick review of the biggest PHP release since 5.3.

Transcript

1. <?PHP 7 PHP developers don’t know how to count
2. PHP 7 Highlights • Scalar type declarations • Return type declarations • Null coalesce operator ?? • Combined comparison operator <=> • Anonymous classes • Way faster then previous release
3. Scalar Typehints • bool, float, int, string • declare(strict_types=1) • function sum(int $a, int $b) {
 return $a + $b
 }
4. Return type declarations • Same types as for argument type declarations • function sum(int $a, int $b):int {
 return $a + $b
 }
5. Null coalesce operator
 ?? • Because we are lazy and other languages have it • $u = isset($_GET['user']) ? $_GET['user'] : 'nobody';
 
 becomes
 
 $u = $_GET['user'] ?? 'nobody';
6. Combined comparison operator <=> • aka Spaceship operator • sorting the right way • echo 1 <=> 1; // 0
 echo 1 <=> 2; // -1
 echo 2 <=> 1; // 1
7. Anonymous classes • Throwaway objects made easy • Testers rejoice • $app = new Application;
 $app->setLogger(new class implements Logger {
 public function log(string $msg) {
 echo $msg;
 }
 });
8. 2X faster?! • PHP Framework Benchmark available on Github: http://rtr.im/y • Virtual machine (2 cores @ 3.4GHz, 4GB RAM) running Ubuntu 14.04 • nginx 1.6 + php-fpm
