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?

Solution 1

Does this work?

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

Solution 2

$results_numeric = (int) $total_results;

or maybe this:

$results_numeric = $total_results->count();

Solution 3

try

class toValue {
    function __toString()
    {
        return '3'; // you must return a string
    }
}

$a = new toValue;

var_dump("$a" + 2);

result: int(5)

Solution 4

perhaps the object has a build in method to get it as an integer?

Otherwise try this very hacky approach (relys on __toString() returning that 10)

$total_results = $total_results->__toString();
$total_results = intval($total_results);

However if the object has a build in non-magic method, you should use that!

Solution 5

You can see the methods of the class here. Then you can try out the different methods yourself. There is a getText() method for example.

(int) does the same as calling intval().

But int is 300 to 600% faster
