This document contains information about PHP including links to Matheus Marabesi's GitHub and Twitter profiles, job opportunities, PHP user groups in Brazil, PHP certification, PHP classes and operators like bitwise operators and object cloning, and PHP functions for sorting arrays and comparing arrays. It also briefly covers object-oriented programming concepts in PHP like late static binding and streams.

WANTED !

11. Who doesn’t
want to be
certified ?

14. ????????

$cachaça = new Cächaça();

22. BITWISE

24. 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

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

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

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

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

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

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

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

0 0 0 0 0 0 1 1 3
0 0 0 0 1 0 0 1 9
print (3 ^ 9);

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

38. 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

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

40. 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

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

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.phpconference.com.br',
false,
$context
);

52. O.O.PObject . Oriented . Programming

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);

60. ARRAY

61. sort();
rsort();
asort();
ksort();
krsort();
usort();

62. A
K
U
R
ASSOCIATIVE
KEY
USER
REVERSE

63. sort();
rsort();
asort();
