php - How to echo custom function -

i have function

function getservertitle() {         return($this->_values[$this->_indexes["servertitle"][0]]["value"]);     }

and wanted echo it, doesn't work.

echo getservertitle();

it shows

fatal error: call undefined function getservertitle()

since body of function contains references $this, not function in older sense of word, non-static method on class.

this implies, way run in meaningfull way instantiate class , call method of resulting object.

e.g.

$object=new your_class_name(); echo $object->getservertitle();
