我已经使用api 从facebook中提取了这个数组

这些是签入的列表。

Array
(
    [data] => Array
        (
            [0] => Array
                (
                    [place] => Array
                        (
                            [id] => 131703340219561
                            [name] => Marrakech
                            [location] => Array
                                (
                                    [city] => Marrakesh
                                    [country] => Morocco
                                    [latitude] => 31.623668132472
                                    [longitude] => -7.98555101201
                                    [zip] => 40000
                                )
                        )
                    [id] => 10151818357364165
                    [created_time] => 2013-08-26T18:05:47+0000
                )
            [1] => Array
                (
                    [place] => Array
                        (
                            [id] => 143805719105986
                            [name] => WESTIVAL Music Festival -31st Jan - 3rd Feb 2013
                            [location] => Westow House
                            [start_time] => 2013-01-31T18:00:00+0000
                        )
                    [id] => 10151702856746562
                    [created_time] => 2013-02-03T00:50:39+0000
                )

我想在数组中搜索并检查是否存在[位置]id。

我该怎么做？

function hasPlaceId($result, $targetId)
{
    if(!array_key_exists('data', $result)
        return false;
    foreach($result['data'] as $value)
    {
        if(array_key_exists('place', $value) && array_key_exists('id', $value['place']) && $value['place']['id'] == $targetId)
            return true;
    }
    return false;
}

使用foreach循环并检查id是否与您所在的位置匹配。

例如：

foreach($aArray['data'] as $iK=> $aData){
  if($iK == 'place'){
    //do something
  }  
  foreach($aData[$iK] as $iV =>$aData2){
    //do something
  }
}
