在PHP中，如何创建和添加对象？

Just so you know I'm working in WordPress. I have an array and want to create an object with only certain values from that array.

Then I have another separate array, I'd like to add to this new object. I might be over complicating things. If I am, please let me know.

Here's what I have so far:

$custom = get_post_custom(); //Gets array of values
$picObject = (object)$custom; //Creates object
$picCount = $custom['picturecount'][0];
for ($x = 1; $x <= $picCount; $x++) {
     // This assembles a URL that I want to add to the array. 
     $finalUrl = $picUrl.$gsi.'&picfilename='.$vin.'_00'.$x.'.jpg';
}

Let me know if you need anything else. Thanks in advance everyone!

If you want to create an object with only some values from your array, you shouldn't cast the array because you'll end up with all of its values. Instead, create a new object and set the values you want:

$array = array(
    'foo' => 'bar',
    'bar' => 'baz'
);

$object = new stdClass();

$object->bar = $array['bar'];
$object->something_else = 'w00t!';

Casting an array to object (i.e. (object)$array) will get you the same type of object, so you can still use $object->new_property = 'foo'; to add stuff to it.
