21. BITWISE

23. a bitwise operation operates on one or more
bit patterns or binary numerals at the level of
their individual bits.
It is a fast, primitive action directly supported
by the processor, and is used to manipulate
values for comparisons and calculations

24. & AND
| OR
^ XOR
>> RIGHT
<< LEFT

25. Bits that are set in
both $a AND $b
are set.
http://php.net/manual/en/language.operators.bitwise.php

26. & - AND
0 & 0 = 0
0 & 1 = 0
1 & 0 = 0
1 & 1 = 1
print (4 & 8);

27. Bits that are set in
either $a OR $b
are set.
http://php.net/manual/en/language.operators.bitwise.php

28. | - OR
0 | 0 = 0
0 | 1 = 1
1 | 0 = 1
1 | 1 = 1
print (2 | 7);

29. Bits that are set in
$a OR $b but not
BOTH are set.
http://php.net/manual/en/language.operators.bitwise.php

30. | - XOR
0 ^ 0 = 0
0 ^ 1 = 1
1 ^ 0 = 1
1 ^ 1 = 0
print (3 ^ 9);

36. & AND
| OR
^ XOR
>> RIGHT
<< LEFT

37. Shift the bits of $a
$b steps to the right
(each step means
"divide by two")
http://php.net/manual/en/language.operators.bitwise.php

38. bit leftmost / 2 ^ bit rightmost
>> - Shift right
print (4 >> 6);
4 / 2 ^ 6 = 0

39. Shift the bits of $a $b
steps to the left (each
step means "multiply
by two")
http://php.net/manual/en/language.operators.bitwise.php

40. bit leftmost * 2 ^ bit rightmost
<< - Shift left
print (7 << 9);
7 * 2 ^ 9 = 3584

41. & AND
| OR
^ XOR
>> RIGHT
<< LEFT

42. Bits that are set in
$a are not set, and
vice versa.
http://php.net/manual/en/language.operators.bitwise.php

43. ~ - Not
~x = -x -1
print (~9);
~9 = -9 -1 = -10

47. STREAMS

49. $context = stream_context_create([
'http' => [
'method' => 'GET'
]
]);
print file_get_contents(
'http://api.phpconference.com.br',
false,
$context
);

50. $context = stream_context_create([
'http' => [
'method' => 'POST',
'header' => 'Content-Type: application/x-www-form-urlencoded',
'content' => 'field=value'
]
]);
print file_get_contents(
'http://api.tdc2016floripa.com.br',
false,
$context
);

53. LATE STATIC BINDING
X
SELF

54. class A {
public static function who() {
echo __CLASS__;
}
public static function test() {
self::who();
}
}
class B extends A {
public static function who() {
echo __CLASS__;
}
}
B::test();

55. class A {
public static function who() {
echo __CLASS__;
}
public static function test() {
static::who();
}
}
class B extends A {
public static function who() {
echo __CLASS__;
}
}
B::test();

56. OBJECT CLONING

57. class A {
public $name;
}
$a = new A();
$b = clone $a;
var_dump($a == $b);

58. class A {
public $name;
}
$a = new A();
$a->name = 'Ana';
$b = clone $a;
$b->name = 'Clark';
var_dump($a == $b);

59. class B {
public $lastName;
}
class A {
public $name;
public $lastName;
public function __construct()
{
$this->lastName = new B();
}
}
$a = new A();
$a->lastName->lastName = 'River';
$b = clone $a;
$b->lastName->lastName = 'Dom';
var_dump($a == $b);
