Kevin,
im not sure why you need the RecursiveIteratorIterator; the
RecursiveArrayIterator is capable of handling the nested arrays by itself.
here is a revision of the code you posted, using PHP_EOL for newlines since
i developed this via the CLI.
<?php
$array = array(
array('name'=>'butch', 'sex'=>'m', 'breed'=>'boxer'),
array('name'=>'fido', 'sex'=>'m', 'breed'=>'doberman'),
array('name'=>'girly','sex'=>'f', 'breed'=>'poodle')
);
$iterator = new RecursiveArrayIterator($array);
printArrayKeysRecursively($iterator);
function printArrayKeysRecursively(RecursiveArrayIterator
$theRecursiveArrayIterator) {
while($theRecursiveArrayIterator->valid()) {
/// handle the current node
if($theRecursiveArrayIterator->hasChildren()) { // determine if the
algorithm should recurse to a child
$innerRecursiveArrayIterator = $theRecursiveArrayIterator->getChildren();
printArrayKeysRecursively($innerRecursiveArrayIterator); // handle printing
of children
} else { // print current node
echo $theRecursiveArrayIterator->key() . ' => ' .
$theRecursiveArrayIterator->current() . PHP_EOL;
}
$theRecursiveArrayIterator->next(); // move to the next node
}
}
?>
here is the output on my box:
nathan@nnppc ~ $ php testRecursiveIterator.php
name => butch
sex => m
breed => boxer
name => fido
sex => m
breed => doberman
name => girly
sex => f
breed => poodle

When I run the code below, I get an output of the array which is good.
But the first member of the array output is 0=>Array. Is there a way to
prevent this? eg:
0 -- Array
name -- butch
sex -- m
breed -- boxer
name -- fido
sex -- m
breed -- doberman
name -- girly
sex -- f
breed -- poodle
<?php
$array = array(
array('name'=>'butch', 'sex'=>'m', 'breed'=>'boxer'),
array('name'=>'fido', 'sex'=>'m', 'breed'=>'doberman'),
array('name'=>'girly','sex'=>'f', 'breed'=>'poodle')
);
$iterator = new RecursiveIteratorIterator(new
RecursiveArrayIterator($array));
while($iterator->valid())
{
echo $iterator->key().' -- '.$iterator->current().'<br/>';
$iterator->next();
}
?>
Kind regards
Kevin
