使用stdClass对象遍历php数组

Question

How do I loop through this array and get all the term_id's?

Array (
    [0] => stdClass Object (
        [term_id] => 43
    )
    [1] => stdClass Object (
        [term_id] => 25
    )
)

Answer 1

$ob1 = new stdClass();
$ob1->term_id = 43;

$ob2 = new stdClass();
$ob2->term_id = 25;

$scope = array($ob1,$ob2);

foreach($scope as $o){
  echo $o->term_id.'<br/>';
}

// Out
// 43
// 25

Answer 2

Each element of your array is an regular object, so yo can access it just by for (if elements of array are in order and keys are integers) or foreach (in examples $a is given array):

For:

$count = sizeof($a);
for ($i = $count; $i--;)
{
    echo $a[$i]->term_id;
}

Foreach:

foreach ($a as $item)
{
    echo $item->term_id;
}

If you want to add all ids to another array, you just need to write following code (in example for foreach):

$ids = array();
foreach ($a as $item)
{
    $ids[] = $item->term_id;
}
