I have a function called init on my website in an external file called functions.php. Index.php loads that page and calls function init:
function init(){
error_reporting(0);
$time_start = microtime(true);
$con = mysql_connect("localhost","user123","password123");
mysql_select_db("db123");
}
How can I get all of these variables global(if possible) without having to use
global $time_start;
global $con;
You don't want it global.
On alternative is to encapsulate it in a object or even use a DI in order to configure it.
If you want to specifically use globals, take a look at $GLOBALS array. Even though there are couple of other ways, Pass by reference, Data Registry Object recommended, etc.
Maybe you can return these variables from your init() function :
function init(){
error_reporting(0);
$time_start = microtime(true);
$con = mysql_connect("localhost","user123","password123");
mysql_select_db("db123");
return array('time_start' => $time_start, 'con' => $con);
}
You can declare them in the global scope, then pass them to the function by reference. After modifying the function to do so.
