如何在输出窗口中运行Netbeans？

Question

I am currently learning PHP but when I try to run the codes, It's opening a browser and it annoys me cause I cannot follow the course I am taking, I got these codes to display

function __construct($tempFirst="",  $tempLast="", $tempYear="") {
    echo "Person Constructor 
".PHP_EOL;
    $this->firstName = $tempFirst;
    $this->lastName = $tempLast;
    $this->yearBorn = $tempYear;
}

but on other browser the next line is not functioning, and on my OUTPUT windows is blank? please help me run it only in Output window, I want the result only in output window and not open a window when I run, the course I follow only displays output on Output window?
