PHP: Count a stdClass object
The object doesn't have 30 properties. It has one, which is an array that has 30 elements. You need the number of elements in that array.
The count function is meant to be used on
- Arrays
- Objects that are derived from classes that implement the countable interface
A stdClass is neither of these. The easier/quickest way to accomplish what you're after is
$count = count(get_object_vars($some_std_class_object));
This uses PHP's get_object_vars function, which will return the properties of an object as an array. You can then use this array with PHP's count function.
The problem is that count is intended to count the indexes in an array, not the properties on an object, (unless it's a custom object that implements the Countable interface). Try casting the object, like below, as an array and seeing if that helps.
$total = count((array)$obj);
Simply casting an object as an array won't always work but being a simple stdClass object it should get the job done here.
