Excuse me, but I am relatively new to php.
While attempting to integrate FUDforum into my existing site, I found that a few global variables are the same as what I am currently using.
Changing WWW_ROOT_DIR to FUD_WWW_ROOT_DISK forum-wide appears to work correctly until I attempt to enter the administration section. I receive the following two errors:
Fatal error: Maximum execution time of 30 seconds exceeded in C:\Program Files\Apache Group\Apache2\forum\include\glob.inc on line 35
Fatal error: Maximum execution time of 30 seconds exceeded in C:\Program Files\Apache Group\Apache2\forum\include\core.inc on line 24
This occurs on both windows and linux boxes. This even persists after I change FUD_WWW_ROOT_DISK back to WWW_ROOT_DISK forum-wide. I thought that the FUD_WWW_ROOT_DISK may have been saved into memory, but a reboot of either box did not resolve the errors. So, one by one, I replaced each file that had the variable changed and attempted to open the administration pages after each change. Alas, when replacing the GLOBALS_HELP with the original, I could access the administration pages. I opened both the altered GLOBALS_HELP and the original GLOBALS_HELP. I found no difference between the two other than a file size difference. All hidden characters appeared to be the same also.
Altered GLOBALS_HELP: 13.2kb
Original GLOBALS_HELP: 12.8kb
This is not my major concern, but an explanation might help in with problems which may arise in the future. Knowing the reason behind why adding and then removing 4 characters would leave a file wih two different sizes?
My major concern is understanding the following:
function read_help() in glob.inc has trouble with my prepending "FUD_" to any GLOBAL variables. I have studied this function and have the basics of what it does, but am having a bit of trouble deciphering it in it's entirety. Might someone with more knowledge than I aid me in understanding it more?
function read_help()
{
/* retrieve GLOBALS_HELP file and set data to contents */
$data = file_get_contents($GLOBALS['INCLUDE'].'GLOBALS_HELP');
/* $len is number of characters of $data */
$len = strlen($data);
/* set $p to 0 as a starting position */
$p = 0;
/* while $p (position) has a real value */
while (($p = strpos($data, "\n", $p)) !== FALSE) {
/* if $p (position) +1 is greater than or equal
to $len, break from loop */
if (++$p >= $len) {
break;
}
/* ????????????? */
if ($data[$p] < 'A' || $data[$p] > 'Z') {
continue;
}
/* $ke is position of the next new line */
$ke = strpos($data, "\n", $p);
/* $key is the string (var_name) from position
$ke to $p */
$key = substr($data, $p, ($ke - $p));
/* $ke + 1 */
++$ke;
/* $e is position of end of GLOBALS variable
definition signified by a period and
double new line */
$e = strpos($data, ".\n\n", $ke);
/* definine array $key's value by using
information between end of GLOBALS
var_name value and end of GLOBALS
var_name */
$help_ar[$key] = nl2br(htmlspecialchars(substr($data, $ke, ($e - $ke))));
/* ????????????? */
$p = $e + 2;
/* if $p (position) is greater than or equal to
$len, break from loop */
if ($p >= $len) {
break;
}
}
/* add to $help_ar */
return (isset($help_ar) ? $help_ar : NULL);
}
I appreciate any help. I do enjoy different code and learning new ways to accomplish a task, but time is a commodity I cannot afford at this time.
