Post the code.

 

edit_information.php

 

 

require_once("../includes/functions.php");

$get_day = substr($get_birthdate,8,;
$get_month = substr($get_birthdate,5,2);
$get_year = substr($get_birthdate,0,4);

global $get_day;
global $get_month;
global $get_year;

 

 

I want to use that $get_day, $get_month and $get_year to one of the function in function.php

 

like this

 

function me_date_dropdown($year_limit = 0){

if($get_day == $day)
{
  //output something here
}


}

The global keyword means nothing outside of a function.

 

It is used:

 

$a = 'foo';

function something() {
  global $a;
  echo $a;
}

something();

 

Having said that. Globals completely break the encapsulation that function provide. You should pass data to functions via there arguments.

Now I get it! It's now working!

 

Thanks Thorpe!

Just to reiterate the recommended method:

$a = 'foo';

function something($param) {
  echo $param;
}

something($a);

Avoid using global whenever possible, which it should be just about every single time.
