如何挖掘多维数组？

Array (
[0] => Array (
[PACKAGE] => Array (
[0] => Array (
[ATTRIBUTES] => Array (
[ID] => 0
)
[ZIPORIGINATION] => Array (
[0] => Array (
[VALUE] => 32751
)
)
[ZIPDESTINATION] => Array (
[0] => Array (
[VALUE] => 55967
)
)
[POUNDS] => Array (
[0] => Array (
[VALUE] => 0
)
)
[OUNCES] => Array (
[0] => Array (
[VALUE] => 9
)
)
[CONTAINER] => Array (
[0] => Array (
[VALUE] => Flat Rate Box
)
)
[SIZE] => Array (
[0] => Array (
[VALUE] => REGULAR
)
)
[ZONE] => Array (
[0] => Array (
[VALUE] => 6
)
)
[POSTAGE] => Array (
[0] => Array (
[MAILSERVICE] => Array (
[0] => Array (
[VALUE] => Priority Mail<sup>®</sup> Medium Flat Rate Box
)
)
[RATE] => Array (
[0] => Array (
[VALUE] => 11.35
)
)
)
)
)
)
)
)
Array (
[0] => price Object (
[mailservice] => Priority Mail<sup>®</sup> Medium Flat Rate Box
[rate] => 11.35
)
)...yeah。我需要搜索这些值并提取Rate值，这里是11.35。
到目前为止，For/each循环让我失望了，还有其他想法吗？

下面是一个为您完成此操作的函数：
findKey($myarray,$searchKey) {
foreach($myarray as $key=>$value) {
if($key==$searchKey) return $value;
if(is_array($value) || is_object($value)) {
$returned = findKey($value,$searchKey);
if($returned) return $returned;
}
}
return false;
}
// call it like this:
findKey($yourArray,"rate")页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
