Traverse a complex array of nested arrays using PHP -

Traverse a complex array of nested arrays using PHP -

i need new idea's, have tried different approach's using foreach statement along iteratorts in php5. parsing response ups multi bundle rate response.

the api returns of service offerings, ground, next day air etc. want focus in key service array holds 'code' value. 1 time find's right service value, when want pull array ratedpackages traverse different services , costs of each package.

i have tried next code no avail, rather see different approaches, not master when comes parsing arrays. is improve send array different construction such json etc. have no idea.

solution expected when 'service array fellow member code - 01 when need pull rated packages array can produce shipping label.

if has improve aproach open , suggestions, if not clear inquire me question , respond best of ability.

thank in advance

anyway here code:

try { $object = new arrayiterator( $arr ); $object->rewind(); while( $object->valid()){ echo $object->key(). "-&gt; ". $object->current()."<br>"; if(is_array($object->current())) { foreach($object->current() $node => $value) { //echo "item: ".$item. " value: ".$value. "<br>"; if($node == 'service') { if(is_array($value)) { s($value->code); foreach($value $item => $v){ echo "item: ".$item. " value: ".$v. "<br>"; if($v == '01'){ echo "hit our mark!!!!!!!"; $rp = $node[0]['ratedpackage']; s("rp: ".$node); } } } } } } $object->next(); } } grab (exception $e) { echo $e->getmessage(); }

output code
