[TECK]

ok, now firefly(or any experienced hacker)... i have another prob... when i try to replace the number of threads in forumhome, i get stuck. here's what i did:
i opened functions.php and located the $threadcount. then i got amased with the + in there:

$threadcount[high]+[/high]=$getchildforum[threadcount];

if it wouldnt be that +, i would do this:

PHP Code:

$threadcount=$getchildforum[threadcount];
$threadcountimage='<img src="'.implode('.gif"><img src="',preg_split('//',(string) $threadcount,-1,PREG_SPLIT_NO_EMPTY)).'.gif">'; 


can i do this?

PHP Code:

$threadcount+=$getchildforum[threadcount];
$threadcountimage='<img src="'.implode('.gif"><img src="',preg_split('//',(string) $threadcount+,-1,PREG_SPLIT_NO_EMPTY)).'.gif">'; 


can you explain to me please what the + do?
thanks alot.
