Question

I made this object array

$trailheads[] = new StdClass;

Then I was putting an object in there each time it looped

$trailheads[] = $trailhead;

Then I returned the whole thing from the function like this:

$ret->ok = empty($errors);
$ret->errors = $errors;
$ret->o = $trailheads;

return $ret;

Once I got the values back, and loop through the results in the trailheads[] I keep looping 3 times instead of the expected 2. Is there a reason an extra iteration might be happening?

Here is how I try to loop:

foreach ($trailhead_list->o as $key)
{
    $objkey  = (object) $key;
    echo '<p><h3>Trailhead Name: '.$objkey->trailhead_name.'</h3></p>';
    }

After this:

$trailheads[] = new StdClass;

your $trailheads array contains on element, an instance of StdClass.

Then you add more elements, but there will be that first one.

Maybe you wanted to initialize the $trailheads[] like that, but instead you gave value to one of the array elements. Use this instead:

$trailheads = array();
