La classe ArrayIterator

Introduction

Cet itérateur permet de réinitialiser et de modifier les valeurs et les clés lors de l'itération de tableaux et d'objets.

Lorsque vous voulez itérer le même tableau plusieurs fois, vous devez instancier ArrayObject et le laisser créer les instances ArrayIterator qui s'y réfère, soit en utilisant l'instruction foreach, soit en appelant la méthode getIterator() manuellement.

Synopsis de la classe

ArrayIterator
ArrayIterator implements Iterator , Traversable , ArrayAccess , SeekableIterator , Countable {
/* Méthodes */
mixed ArrayIterator::current ( void )
mixed ArrayIterator::key ( void )
void ArrayIterator::next ( void )

Another fine Iterator from php . You can use it especially when you have to iterate over objects

<?php
$fruits
= array(
   
"apple" => "yummy",
   
"orange" => "ah ya, nice",
   
"grape" => "wow, I love it!",
   
"plum" => "nah, not me"
);
$obj = new ArrayObject( $fruits );
$it = $obj->getIterator();

// How many items are we iterating over?

echo "Iterating over: " . $obj->count() . " values\n";

// Iterate over the values in the ArrayObject:
while( $it->valid() )
{
    echo
$it->key() . "=" . $it->current() . "\n";
   
$it->next();
}

// The good thing here is that it can be iterated with foreach loop

foreach ($it as $key=>$val)
echo
$key.":".$val."\n";

/* Outputs something like */

Iterating over: 4 values
apple
=yummy
orange
=ah ya, nice
grape
=wow, I love it!
plum=nah, not me

?>

Regards.
