Get Clicky Smilies

[gmarik]

Could you comment every line of this code, I can't get it really working for me. I want to make a hack, but ...



// prevent division by zero errors
if ($smcolumns==0) {
return;
}

$tableRows = ceil($numSmilies/$smcolumns);

for ($i=0; $i<$tableRows; $i++) {
$smiliebits .= "<tr align='center'>\n";
for ($j=0; $j<$smcolumns; $j++) {
$smiliebits .= "<td>".$smilieArray[$count++]."&nbsp;</td>\n";
}
$smiliebits .= "</tr>\n";
}
