访问对象值

Question

I am trying to pull out a value from inside a larger object. The main object from an xml file via SimpleXML.

When I var_dump($data->extensions->runTime); this section of the object I get:

object(SimpleXMLElement)#21 (1) {
  [0]=>
  string(8) "2852.462"
}

How can I access that 2852.462??

I have tried everything I can think of, via array [0], even with a foreach statement. I can't figure out how to access only the value.

Answer 1

Cast it to string:

$value = (string)$data->extensions->runTime[0];

Or better to float:

$value = (float)$data->extensions->runTime[0];
