PHP While Loop!?

(1/2) > >>

ziycon:
Maybe its due to me looking at the code so long I just can't see whats going on but can anyone tell me why the below code is timing out?


--- Code: ---$level = 1;

while($level >= 0) {
$breadcrumbNav = $linkArray[$level][1].$breadcrumbNav;
        // $linkArray[$level][5] will always be less then the current value for $level but not always a concurrent decrement
$level = $linkArray[$level][5];
}
--- End code ---

The Burglar!:
global variable is $linkarray is used before its defined

ziycon:
Sorry, I should have said, everything is defined before hand, there is so much code I didn't post it all as I think its an issue with my logic in the while loop as if I change the below line:

--- Code: ---$level = $linkArray[$level][5];
--- End code ---

To:

--- Code: ---echo $linkArray[$level][5];
$level--;
--- End code ---

It outputs ok.

The Burglar!:
 i debugged the code coz m lazy today... while ihave not full code cant make any sense out of it...the output is debugged oke anyway... got just 2 errors before the globals are defined before they are used :P

$breadcrumbNav

and

$linkArray

ziycon:
Maybe this might make more sense, I cleaned it up to remove non relevant code.


--- Code: ---$linkParent = array();
$currentPage =  $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];

$linkArray = self::getNavArray(); // returns an array of all available links on the site in the format (id, link_text, link, sequence, pages_to_display_on, parent)

for($i=0;$i<sizeof($linkArray);$i++) {
if(strstr($currentPage,$linkArray[$i][2]))
$linkParent = $linkArray[$i][5];
}

$level = $linkParent;

while($level >= 0) {
$breadcrumbNav = $linkArray[$level][1].$breadcrumbNav;
$level = $linkArray[$level][5];
}
--- End code ---
