Question

我有这个数组：

Array ( [0] => Array ( [asset] => track [path] => media/promenade_web/AUDIO/promenade-arkadiev.mp3 [file_name] => promenade-arkadiev [permission_audio_play_synchronization] => Array ( [synchronization] => Array ( [constraint] => Array ( [numberOfMeasures] => Array ( [startMeasure] => 1 [number] => 10 ) [qualityOfResource] => medium ) [requirement] => Array ( ) [condition] => Array ( ) ) [play] => Array ( [constraint] => Array ( [numberOfMeasures] => Array ( [startMeasure] => 1 [number] => 10 ) [qualityOfResource] => medium [spatial] => iso3166:CH,IT [count] => 10 [datetime] => Array ( [start] => 2017-08-16 [end] => 2017-10-20 ) [accumulated] => P30D [format] => mp3,wav ) [requirement] => Array ( ) [condition] => Array ( ) ) ) ) [1] => Array ( [asset] => track [path] => media/promenade_web/AUDIO/promenade-arkadiev_lo.mp3 [file_name] => promenade-arkadiev_lo [permission_audio_play_synchronization2] => Array ( [play] => Array ( [constraint] => Array ( [numberOfMeasures] => Array ( [startMeasure] => 1 [number] => 10 ) [qualityOfResource] => medium [spatial] => iso3166:CH,IT [count] => 10 [datetime] => Array ( [start] => 2017-08-16 [end] => 2017-10-20 ) [accumulated] => P30D [format] => mp3,wav ) [requirement] => Array ( [prepay] => Array ( [amount] => 0.99 [currency] => EUR ) ) [condition] => Array ( ) ) ) ) )

无论子数组的数量如何，如何找到foreach的值？

我已尝试使用此代码，但它无法正常工作：

function recursive_array_search($needle, $haystack, $currentKey = '') {
    foreach($haystack as $key=>$value) {
        if (is_array($value)) {
            $nextKey = recursive_array_search($needle,$value, $currentKey . '[' . $key . ']');
            if ($nextKey) {
                return $nextKey;
            }
        }
        else if($value==$needle) {
            return is_numeric($key) ? $currentKey . '[' .$key . ']' : $currentKey;
        }
    }
    return false;
}

我总是在多维数组上使用以下

 $arr = array(array('id'=>1,'name'=>'nilesh'),array('id'=>2,'name'=>'ajay'));
    echo "<pre>";
    print_r($arr[array_search('nilesh', array_column($arr,'name'))]);
    echo "</pre>";

如何在子多维数组中找到值？
