Description: I'm sure there's others. Includes a small function to strip whitespace.
<?
/********************************************************************************\
Here's example ini settings:
Lines beginning with ; are obviously ignored.
; returns $array['foo'] = "bar"
foo=bar
; returns $array['foo'] = "bar.com/?foo=bar"
foo=bar.com/?foo=bar
; returns $array['foo'][0] = "foo" and $array['foo'][1] = "bar"
foo=foo,bar
\********************************************************************************/
// strip a string of whitespace

{

$replacement = "";
$new_string = preg_replace( $match , $replacement , $string );
return $new_string;
}
// gather settings from specified ini file
function settings( $ini )
{
$fp = 0; // the ini's file pointer
