Conditionally grab a parameter from a URL

In PHP, I have a webpage: http://www.example.com/index.php?param=val&param2=val2&so_on=so_on.

How can I get param's value and put it in $variable only if the parameter is defined in the URL? Otherwise, I want to set $variable to a default value like 123456789. Is this possible? Thanks!

Solution

  • Just use a ternary and it will always be set as you asked

    $var = (isset($_GET['param'])) ? $_GET['param'] : '123456789';
