Question

I declared class which has 1 object . calling method with that object is okay , but calling methods which was not-an-object causing no output .. here it demonstrates

    
                // defining simple class
            class Person{ 
            function say_hello($name='world')
                {
                    echo "hello {$name}";


            }
        }

        $instant1 = new Person();

        $object2 = new Person();

        echo get_class($object2);
        ?>
<br/>
<?php 

if(is_a($object2,'Person'))
{
//remeber to pass arguments 
echo "This object or instant is in that class";
}
else {

echo "No dude :( ";
}

?>



<?php 


$instant1->say_hello('Paritosh');

echo " <br/>";

$ob->say_hello(); // No error No output , even there is no object with name $ob and below code is not running

                      // is it bug or any concept ?
echo "No output ";

    $object2->say_hello(); 
?>


I’m using PHP Version 5.2.17 in IIS Express in webmatrix platform . 
												

Answer 1

$ob ist not a Person, so how should the interpreter know that you want access Person?
if you want to access the function without an object, try:

Person::say_hello();
