如何循环遍历php数组的内容？ [关闭]

Question

I have a php array which I got as a response from a server so I can't change it,

print_r($array); // result is below

 array(
  'responseHeader'=>array(
    'status'=>0,
    'QTime'=>0,
    'params'=>array(
      'indent'=>'true',
      'q'=>'rajnikanth',
      '_'=>'1383362349068',
      'wt'=>'php')),
  'response'=>array('numFound'=>2,'start'=>0,'docs'=>array(
      array(
        'id'=>'31546690',
        'title'=>'Jayan quotes',
        '_version_'=>1450551735544184832),
      array(
        'id'=>'597727',
        'title'=>'List of Internet phenomena',
        '_version_'=>1450551735290429440))
  ))

How to access each of the title values in this array? I tried to use $array[0] but it erred out saying no offset set.

Answer 1

foreach ($array['response']['docs'] as $doc) {
    echo $doc['title'];
}

$array appears to be an array of two keys, responseHeader and response. The response key contains a docs key, which is an array of arrays. Each of these arrays appears to have a title.
