Convert object to integer in PHP

Question

• The value of $total_results = 10
• $total_results in an object, according to gettype()
• I cannot use mathematical operators on $total_results because it's not numeric
• Tried $total_results = intval($total_results) to convert to an integer, but no luck
• The notice I get is: Object of class Zend_Gdata_Extension_OpenSearchTotalResults could not be converted to int

How can I convert to an integer?

Answer 1

Does this work?

$val = intval($total_results->getText());
