PHP Function Accessing Database Connection

Question

How do I allow a function to access a database connection without using GLOBAL?

config.php

 DEFINE (\'DB_HOSTNAME\', \'hostname\');
 DEFINE (\'DB_DAT         


        

Answer 1

There are two ways one is by passing arguments and the other by using function closure like @Ondrej said. But I wonder both of these require you to modify the code if that is the case, then I would suggest you to use global keyword.

You can use global keyword to get the scope of variable $dbc

Try this..

function something()
{
   global $dbc;
   $info = mysqli_query($dbc, "SELECT info FROM text") or die("Error: ".mysqli_error($dbc));
}

(OR)

Try this...

function something()
{
    $dbc = func_get_arg(0);
     $info = mysqli_query($dbc, "SELECT info FROM text") or die("Error: ".mysqli_error($dbc));
}

& do this ....

$query = something($dbc);
