Not understanding why i can't call a function

Question

I am fairly new to PHP. And I really don't understand why I can not call a function.

class test {

    public function sayHi($name, $age)
    {
        echo $name . $age;
    }
}

When trying to call sayHi it does not show up.

Thank you for any input

Where is below the function? If you're calling it inside the class then you can use `$this->sayHi();` — hungrykoala, Jan 22 '18 at 09:25
Just a note; instead of `echo $name . $age;` you should `return $name . $age` and then you would `echo $this->sayHi()` . Welcome to OOP! — IsThisJavascript, Jan 22 '18 at 09:28

Basically you are creating a function inside a class 'test', so you have to call it via a class object. example:

$testObj = new test();
$testObj->sayHi("Jon", 43);

class test {

public function sayHi($name, $age)
 {
 echo $name . $age;
 }
}

$testObject = new test();

$testObject->newTest();

$testObject->sayHi("Name",23);

This line $testObject->newTest(); may confuse to @Robertme. There is no such function declaration inside your code! – Hetal Chauhan Jan 22 '18 at 09:30
