PHP数组访问数组对象的标题名称

I am trying to get the title name of an array object.

For example I have

$results[0]['page']
$results[0]['title']

I was wondering if I could use a for loop to loop through the $results[0] array and get the 'page' and 'title' names and insert them into a new array?

Thanks for your time

foreach ($results[0] as $key=>$value) {
     //Your key will be page and title, and then the value will be in value
}

More information on the PHP documentation for foreach().

Or you could just use array_keys() to turn the assoc indexes into a new array automatically.
