Question

alot of time in programming the value of variables are passed through url parameters,
in php;

if (isset($_GET['var'])) {$var = $_GET['var'];}

But if that does not execute, we will have an unset variable, in which may cause errors in the remaining of the code, i usually set the variable to ” or false;

else {$var = '';}

I was wondering what are the best practices, and why : )

thank you!

Answer 1

create a function

function get($name, $default = "") {
   return isset($_GET[$name]) ? $_GET[$name] : $default;
}
