The ArrayObject class

(PHP 5)

简介

This class allows objects to work as arrays.

ArrayObject implements IteratorAggregate , ArrayAccess , Serializable , Countable {

/* 常量 */

const integer STD_PROP_LIST = 1 ;

const integer ARRAY_AS_PROPS = 2 ;

/* 方法 */

public __construct ([ mixed $input = [] [, int $flags = 0 [, string $iterator_class = "ArrayIterator" ]]] )

public void append ( mixed $value )

public void asort ( void )

public int count ( void )

public array exchangeArray ( mixed $input )

public array getArrayCopy ( void )

public int getFlags ( void )

public ArrayIterator getIterator ( void )

public string getIteratorClass ( void )

public void ksort ( void )

public void natcasesort ( void )

public void natsort ( void )

public bool offsetExists ( mixed $index )

public mixed offsetGet ( mixed $index )

public void offsetSet ( mixed $index , mixed $newval )

public void offsetUnset ( mixed $index )

public string serialize ( void )

public void setFlags ( int $flags )

public void setIteratorClass ( string $iterator_class )

public void uasort ( callable $cmp_function )

public void uksort ( callable $cmp_function )

public void unserialize ( string $serialized )

}

ArrayObject::STD_PROP_LIST: Properties of the object have their normal functionality when accessed as list (var_dump, foreach, etc.).
ArrayObject::ARRAY_AS_PROPS: Entries can be accessed as properties (read and write).
