10. AST
Abstract Syntax Tree
<?php
require ‘path/to/utility.php’;
$code = <<<’EOC’
<?php
$var = 42;
EOC;
echo ast_dump(astparse_code($code, $version = 50)), “n”;
// Output:
AST_STMT_LIST
0: AST_ASSIGN
var: AST_VAR
name: “var”
expr: 42

11. RTD
Return Type Declaration
<?php
function foo($bar):string
{
return $bar;
}
foo(50);
Fatal error:
Uncaught TypeError: Return value of foo() must be of the type string
Steeven Andrian

12. CST
Coercive Scalar Type
<?php
function foo(string $num):string
{
return ‘this is: ’ . $bar;
}
foo(50);
Notice:
A non well formed numeric value encountered in file on line 2

13. SST
Strict Scalar Type
<?php
declare(strict_types = 1);
function foo(string $num):string
{
return ‘this is: ’ . $num;
}
foo(50);
Fatal Error:
Uncaught TypeError: Argument 1 passed to foo() must be of the type string, integer given, called
in line 9 and defined in file: 3
Steeven Andrian

14. Typed
Class Property
<?php
class Example
{
public string $foo = ‘foo’;
}
$example = new Example();
$example->foo = 1;
Fatal Error:
Uncaught TypeError: $foo must be of the type string, integer given, called in line 9 and defined in
file: 3
Steeven Andrian

15. Union Types
Returns and Declaration
<?php
function foo(string|int $num):string|int
{
return $num;
}
foo(50);
foo(‘fifty’);

16. Anonymous Class
<?php
use O2SystemFrameworkModelsSqlModel;
$model = new class extends Model
{
public $table = ‘test_table’;
}
$model->all();

17. Null Coalesce Operator
<?php
$a = null;
$b = 1;
$c = 2;
echo $a ?? $b; // output: 1
echo $c ?? $b; // output: 2
echo $a ?? $b ?? $c; // output: 1
echo $a ?? $x ?? $c; // output: 2

18. Spaceship Operator
<?php
function cmp_php5($a, $b) {
return ($a < $b) ? -1 : (($a > $b) ? 1 : 0);
}
function cmp_php7($a, $b) {
return $a <=> $b
}
|=| // tie fighter
k=k // tie interceptor
<==> // tie bomber
<=> // tie advanced X1

19. Zero-cost Assertions
<?php
function test($args) {
assert ($arg > 20) && $arg < 110, “$arg is invalid”);
}
ini_set(‘zend.assertions’, 0); test(16);
ini_set(‘zend.assertions’, 1); test(17);
ini_set(‘assert.exception’, 1); test(18);
Warning: assert(): 17 is invalid failed in file on line 2
Fatal error: uncaught AssertionError: 18 is invalid in file: 2

20. Added Closure::call()
<?php
$foo = function() {
return $this->num;
}
class MyClass
{
private $num = 42;
}
// PHP v5.x
$class = $foo->bindTo($myClass, “MyClass”);
$class();
// PHP v7.x
$foo->call($myClass);
Steeven Andrian

21. Arrow Function
<?php
$x = 10;
// PHP v5.x
$nums = array_map(function($n) use $x {
return $n * $x;
}, [1,2,3,4]);
// PHP v7.x
$nums = array_map(fn($n) => $n * $x, [1,2,3,4]);
print_r($nums);
// Output: Array(10,20,30,40);

22. Parse Error
on Invalid numeric literals
<?php
$mask = 0855;
Parse error: Invalid numeric literal
Steeven Andrian
The Rise Of PHP

23. Uniform Variable Syntax
<?php
// v7.x Left to Right
$this->$foo[‘bar’];
// v5.x
$this->{$foo[‘bar’]};
// Support missing combinations of operations
$foo()[‘bar’]();
[$obj1, $obj2[0]->prop;
getStr(){0}
// Support operations on arbitrary (...) expressions
(...)[‘foo’];
(...)->foo;
// Support nested ::
$foo[‘bar’]::$baz;
$foo::$bar::$baz;
$foo->bar()::baz();
// Support nested ()
$foo()();
$foo->bar()();
Foo::bar()();
$foo()();

24. Immutable Arrays
Optimization
<?php
$arrays = [];
for($i = 0; $i < 100000; ++$i) {
$arrays[] = [1,2,3,4,5,6]
}
