Detailed Description

An Array iterator.

Since:
PHP 5.0
Version:
1.2
This iterator allows to unset and modify values and keys while iterating over Arrays and Objects.

When you want to iterate over the same array multiple times you need to instanciate ArrayObject and let it create ArrayIterator instances that refer to it either by using foreach or by calling its getIterator() method manually.

Constructor & Destructor Documentation

ArrayIterator::__construct ( array,
flags = 0 
)

Construct a new array iterator from anything that has a hash table.

That is any Array or Object.

Parameters:
$array the array to use.
$flags see setFlags().

Reimplemented in SubClasses.

Member Function Documentation

ArrayIterator::append ( value  ) 

Parameters:
$value is appended as last element

Warning:
this method cannot be called when the ArrayIterator refers to an object.

Definition at line 804 of file spl.php.

ArrayIterator::asort (  ) 

Sort the entries by values.

Definition at line 759 of file spl.php.

ArrayIterator::count (  ) 

Returns:
the number of elements in the array or the number of public properties in the object.

Implements Countable.

newval 
)

Parameters:
$index index to set

Parameters:
$newval new value to store at offset $index
