The Cultural Significance of Kazu Kihybi Amulets in Japan

Kazu kihybi amulet is a unique artifact that holds a significant cultural and historical value in Japanese folklore. This amulet is believed to possess special powers that can protect its wearer from evil spirits and bring them good fortune. The Kazu kihybi amulet is commonly made of various materials such as paper, cloth, or metal and is often adorned with sacred symbols or prayers. It is believed that these amulets are blessed by priests or spiritual leaders in order to amplify their protective abilities. In Japanese culture, the belief in supernatural beings and spirits is deeply rooted. These spirits are thought to have the ability to cause harm or misfortune to humans.

// sort customers by last name
usort ( $customers , new Sort ( 'last_name' ));
print_r ( $customers );
?>

Being able to represent data-holding objects in standardised string forms makes it much easier for your internal representations of data to be shared in an interoperable way with other applications. Be very careful to define __set_state in classes which inherit from a parent using it, as the static __set_state call will be called for any children.

These spirits are thought to have the ability to cause harm or misfortune to humans. To protect themselves, people often turn to amulets like the Kazu kihybi amulet. It is common to see people wearing these amulets around their necks, tied to their bags, or placed in their homes or cars.

Objective magical net

Magic methods are special methods which override PHP's default's action when certain actions are performed on an object.

All methods names starting with __ are reserved by PHP. Therefore, it is not recommended to use such method names unless overriding PHP's behavior.

All magic methods, with the exception of __construct(), __destruct(), and __clone(), must be declared as public , otherwise an E_WARNING is emitted. Prior to PHP 8.0.0, no diagnostic was emitted for the magic methods __sleep(), __wakeup(), __serialize(), __unserialize(), and __set_state().

If type declarations are used in the definition of a magic method, they must be identical to the signature described in this document. Otherwise, a fatal error is emitted. Prior to PHP 8.0.0, no diagnostic was emitted. However, __construct() and __destruct() must not declare a return type; otherwise a fatal error is emitted.

__sleep() and __wakeup()

serialize() checks if the class has a function with the magic name __sleep(). If so, that function is executed prior to any serialization. It can clean up the object and is supposed to return an array with the names of all variables of that object that should be serialized. If the method doesn't return anything then null is serialized and E_NOTICE is issued.

Note:

It is not possible for __sleep() to return names of private properties in parent classes. Doing this will result in an E_NOTICE level error. Use __serialize() instead.

Note:

As of PHP 8.0.0, returning a value which is not an array from __sleep() generates a warning. Previously, it generated a notice.

The intended use of __sleep() is to commit pending data or perform similar cleanup tasks. Also, the function is useful if a very large object doesn't need to be saved completely.

Conversely, unserialize() checks for the presence of a function with the magic name __wakeup(). If present, this function can reconstruct any resources that the object may have.

The intended use of __wakeup() is to reestablish any database connections that may have been lost during serialization and perform other reinitialization tasks.

Example #1 Sleep and wakeup

class Connection
protected $link ;
private $dsn , $username , $password ;

public function __construct ( $dsn , $username , $password )
$this -> dsn = $dsn ;
$this -> username = $username ;
$this -> password = $password ;
$this -> connect ();
>

private function connect ()
$this -> link = new PDO ( $this -> dsn , $this -> username , $this -> password );
>

public function __sleep ()
return array( 'dsn' , 'username' , 'password' );
>

public function __wakeup ()
$this -> connect ();
>
> ?>

__serialize() and __unserialize()

serialize() checks if the class has a function with the magic name __serialize(). If so, that function is executed prior to any serialization. It must construct and return an associative array of key/value pairs that represent the serialized form of the object. If no array is returned a TypeError will be thrown.

Note:

If both __serialize() and __sleep() are defined in the same object, only __serialize() will be called. __sleep() will be ignored. If the object implements the Serializable interface, the interface's serialize() method will be ignored and __serialize() used instead.

The intended use of __serialize() is to define a serialization-friendly arbitrary representation of the object. Elements of the array may correspond to properties of the object but that is not required.

Conversely, unserialize() checks for the presence of a function with the magic name __unserialize(). If present, this function will be passed the restored array that was returned from __serialize(). It may then restore the properties of the object from that array as appropriate.

Note:

If both __unserialize() and __wakeup() are defined in the same object, only __unserialize() will be called. __wakeup() will be ignored.

Note:

This feature is available as of PHP 7.4.0.

Example #2 Serialize and unserialize

class Connection
protected $link ;
private $dsn , $username , $password ;

public function __construct ( $dsn , $username , $password )
$this -> dsn = $dsn ;
$this -> username = $username ;
$this -> password = $password ;
$this -> connect ();
>

private function connect ()
$this -> link = new PDO ( $this -> dsn , $this -> username , $this -> password );
>

public function __serialize (): array
return [
'dsn' => $this -> dsn ,
'user' => $this -> username ,
'pass' => $this -> password ,
];
>

public function __unserialize (array $data ): void
$this -> dsn = $data [ 'dsn' ];
$this -> username = $data [ 'user' ];
$this -> password = $data [ 'pass' ];

__toString()

The __toString() method allows a class to decide how it will react when it is treated like a string. For example, what echo $obj; will print.

As of PHP 8.0.0, the return value follows standard PHP type semantics, meaning it will be coerced into a string if possible and if strict typing is disabled.

As of PHP 8.0.0, any class that contains a __toString() method will also implicitly implement the Stringable interface, and will thus pass type checks for that interface. Explicitly implementing the interface anyway is recommended.

In PHP 7.4, the returned value must be a string , otherwise an Error is thrown.

Prior to PHP 7.4.0, the returned value must be a string , otherwise a fatal E_RECOVERABLE_ERROR is emitted.

It was not possible to throw an exception from within a __toString() method prior to PHP 7.4.0. Doing so will result in a fatal error.

Example #3 Simple example

// Declare a simple class
class TestClass
public $foo ;

public function __construct ( $foo )
$this -> foo = $foo ;
>

public function __toString ()
return $this -> foo ;
>
>

$class = new TestClass ( 'Hello' );
echo $class ;
?>

The above example will output:

Hello

__invoke()

The __invoke() method is called when a script tries to call an object as a function.

Example #4 Using __invoke()

class CallableClass
public function __invoke ( $x )
var_dump ( $x );
>
>
$obj = new CallableClass ;
$obj ( 5 );
var_dump ( is_callable ( $obj ));
?>

The above example will output:

int(5) bool(true)

Example #5 Using __invoke()

public function __construct ( string $key )
$this -> key = $key ;
>

public function __invoke (array $a , array $b ): int
return $a [ $this -> key ] $b [ $this -> key ];
>
>

$customers = [
[ 'id' => 1 , 'first_name' => 'John' , 'last_name' => 'Do' ],
[ 'id' => 3 , 'first_name' => 'Alice' , 'last_name' => 'Gustav' ],
[ 'id' => 2 , 'first_name' => 'Bob' , 'last_name' => 'Filipe' ]
];

// sort customers by first name
usort ( $customers , new Sort ( 'first_name' ));
print_r ( $customers );

// sort customers by last name
usort ( $customers , new Sort ( 'last_name' ));
print_r ( $customers );
?>

The above example will output:

Array ( [0] => Array ( [id] => 3 [first_name] => Alice [last_name] => Gustav ) [1] => Array ( [id] => 2 [first_name] => Bob [last_name] => Filipe ) [2] => Array ( [id] => 1 [first_name] => John [last_name] => Do ) ) Array ( [0] => Array ( [id] => 1 [first_name] => John [last_name] => Do ) [1] => Array ( [id] => 2 [first_name] => Bob [last_name] => Filipe ) [2] => Array ( [id] => 3 [first_name] => Alice [last_name] => Gustav ) )

__set_state()

This static method is called for classes exported by var_export() .

The only parameter of this method is an array containing exported properties in the form ['property' => value, . ] .

Example #6 Using __set_state()

class A
public $var1 ;
public $var2 ;

public static function __set_state ( $an_array )
$obj = new A ;
$obj -> var1 = $an_array [ 'var1' ];
$obj -> var2 = $an_array [ 'var2' ];
return $obj ;
>
>

$a = new A ;
$a -> var1 = 5 ;
$a -> var2 = 'foo' ;

$b = var_export ( $a , true );
var_dump ( $b );
eval( '$c = ' . $b . ';' );
var_dump ( $c );
?>

The above example will output:

string(60) "A::__set_state(array( 'var1' => 5, 'var2' => 'foo', ))" object(A)#2 (2) < ["var1"]=>int(5) ["var2"]=> string(3) "foo" >

Note: When exporting an object, var_export() does not check whether __set_state() is implemented by the object's class, so re-importing objects will result in an Error exception, if __set_state() is not implemented. Particularly, this affects some internal classes. It is the responsibility of the programmer to verify that only objects will be re-imported, whose class implements __set_state().

__debugInfo()

This method is called by var_dump() when dumping an object to get the properties that should be shown. If the method isn't defined on an object, then all public, protected and private properties will be shown.

Example #7 Using __debugInfo()

public function __construct ( $val ) $this -> prop = $val ;
>

public function __debugInfo () return [
'propSquared' => $this -> prop ** 2 ,
];
>
>

var_dump (new C ( 42 ));
?>

The above example will output:

object(C)#1 (1) < ["propSquared"]=>int(1764) >

User Contributed Notes 22 notes

The __toString() method is extremely useful for converting class attribute names and values into common string representations of data (of which there are many choices). I mention this as previous references to __toString() refer only to debugging uses.

I have previously used the __toString() method in the following ways:

- representing a data-holding object as:
- XML
- raw POST data
- a GET query string
- header name:value pairs

- representing a custom mail object as an actual email (headers then body, all correctly represented)

When creating a class, consider what possible standard string representations are available and, of those, which would be the most relevant with respect to the purpose of the class.

Being able to represent data-holding objects in standardised string forms makes it much easier for your internal representations of data to be shared in an interoperable way with other applications.

Be very careful to define __set_state() in classes which inherit from a parent using it, as the static __set_state() call will be called for any children. If you are not careful, you will end up with an object of the wrong type. Here is an example:

public static function __set_state ( $an_array )
<
$obj = new A ;
$obj -> var1 = $an_array [ 'var1' ];
return $obj ;
>
>

class B extends A <
>

$b = new B ;
$b -> var1 = 5 ;

eval( '$new_b = ' . var_export ( $b , true ) . ';' );
var_dump ( $new_b );
/*
object(A)#2 (1) <
["var1"]=>
int(5)
>
*/
?>

__debugInfo is also utilised when calling print_r on an object:

$ cat test.php
class FooQ

public function __construct ( $val )

public function __debugInfo ()
return [ '_bar' => $this -> bar ];
>
>
$fooq = new FooQ ( "q" );
print_r ( $fooq );

$ php test . php
FooQ Object
(
[ _bar ] => q
)
$

IMHO a bug or need feature change

providing a object as a array index doesn't try to us __toString() method so some volatile object identifier is used to index the array, which is breaking any persistency. Type hinting solves that, but while other than "string" type hinting doesn't work on ob jects, the automatic conversion to string should be very intuitive.

PS: tried to submit bug, but withot patch the bugs are ignored, unfortunately, I don't C coding

protected $shop_name ;
protected $product_id ;

function __construct ( $shop_name , $product_id ) $this -> shop_name = $shop_name ;
$this -> product_id = $product_id ;
>

function __toString () return $this -> shop_name . ':' . $this -> product_id ;
>
>

$shop_name = 'Shop_A' ;
$product_id = 123 ;
$demo_id = $shop_name . ':' . $product_id ;
$demo_name = 'Some product in shop A' ;

$all_products = [ $demo_id => $demo_name ];
$pid = new shop_product_id ( $shop_name , $product_id );

echo "with type hinting: " ;
echo ( $demo_name === $all_products [(string) $pid ]) ? "ok" : "fail" ;
echo "\n" ;

echo "without type hinting: " ;
echo ( $demo_name === $all_products [ $pid ]) ? "ok" : "fail" ;
echo "\n" ;

If you use the Magical Method '__set()', be shure that the call of
$myobject -> test [ 'myarray' ] = 'data' ;
?>
will not appear!

For that u have to do it the fine way if you want to use __set Method ;)
$myobject -> test = array( 'myarray' => 'data' );
?>

If a Variable is already set, the __set Magic Method already wont appear!

My first solution was to use a Caller Class.
With that, i ever knew which Module i currently use!
But who needs it. :]
There are quiet better solutions for this.
Here's the Code:

class Caller public $caller ;
public $module ;

function __call ( $funcname , $args = array()) $this -> setModuleInformation ();

$this -> unsetModuleInformation ();
return $return ;
>

function __construct ( $callerClassName = false , $callerModuleName = 'Webboard' ) if ( $callerClassName == false )
trigger_error ( 'No Classname' , E_USER_ERROR );

$this -> module = $callerModuleName ;

if ( class_exists ( $callerClassName ))
$this -> caller = new $callerClassName ();
else
trigger_error ( 'Class not exists: \'' . $callerClassName . '\'' , E_USER_ERROR );

if ( is_object ( $this -> caller ))
$this -> setModuleInformation ();
if ( method_exists ( $this -> caller , '__init' ))
$this -> caller -> __init ();
$this -> unsetModuleInformation ();

else
trigger_error ( 'Caller is no object!' , E_USER_ERROR );

$this -> unsetModuleInformation ();

unset( $this -> caller ->< $unset >);

trigger_error ( 'Caller is no object!' , E_USER_ERROR );
$this -> unsetModuleInformation ();

function __set ( $set , $val ) $this -> setModuleInformation ();
if ( is_object ( $this -> caller ))
$this -> caller -> < $set >= $val ;
else
trigger_error ( 'Caller is no object!' , E_USER_ERROR );
$this -> unsetModuleInformation ();

function __get ( $get ) $this -> setModuleInformation ();
if ( is_object ( $this -> caller )) if (isset( $this -> caller ->< $get >))
$return = $this -> caller ->< $get >;
else
$return = false ;

trigger_error ( 'Caller is no object!' , E_USER_ERROR );
$this -> unsetModuleInformation ();
return $return ;
