using global var (global settings?)

[Sonnich]

Hi all!

I have an app which reads from certain servers, but I'd like to have
them in am ini-file.

I made this up, but I need those vars to be visible in functions
too.... how do I do that?

// default ini values
$dir1="\\\\serv er1\\finance";
$dir2="\\\\serv er2\\design\\";
// read in settings
$ini=fopen("con fig.ini", "r");
while(!feof($in i))
{
$line=fgets($in i, 100);
if(stristr($lin e, 'dir1') == TRUE)
{
$dir1=strstr($l ine, '=');
$dir1=trim(subs tr($dir1, 1, 1000));
}
else if(stristr($lin e, 'dir2') == TRUE)
{
$dir2=strstr($l ine, '=');
$dir2=trim(subs tr($dir2, 1, 1000));
}
}
fclose($ini);

Various options, some of which are:

(1) Access the configuration values through functions instead of globals.
(2) Define them as constants; they're always in scope.
(3) Use the "global" statement in the function.
(4) Reference the variables through $GLOBALS.
(5) It sounds like you want to register your own superglobals - this is not
trivial; runkit can do it, but that's fairly magic and unlikely to be installed
on most servers. http://www.php.net/manual/en/runkit.sandbox.php
