Optional Arguments

[Arkane]

Hey folks

I'm trying to teach myself some PHP, and I've managed to make a working script with arguments in the url.

 

So far I have file.php?name=Leroux

 

I'm looking to change it to have a secondary argument which is optional.

 

eg file.php?name=Leroux&lives=UK

 

I know how to do it as a required, but my method tends to break it if the parameter isnt there.

Any suggestions?

Cheers guys

<?php
  if(isset($_GET['lives'])){
    $lives = $_GET['lives'];
  }else{
    $lives = 123; //Default value
  }
  echo $lives;
?>

 

or shorthand:

 

$lives = isset($_GET['lives']) ? $_GET['lives'] : 123;
