code symbol trouble

[viveleroi0]

I am trying to understand a bit of code, and I know most of it, but what does the % symbol mean in the second line?

$pages=intval($num/$limit);
if ($num%$limit) {

% is operator modulus 🙂

7 % 6 you get 1

7 divided 6 and the reminder is 1

How would that work in the following code? It doesn't make sense, it's like saying: if (remainder of $num/$limit), so it could be like if (1) which doesn't sound right. I'm used to IF 7 is equal or not to something. What is it asking?

$pages=intval($num/$limit);
if ($num%$limit) {
$pages++;}
for ($i = 1; $i <= $pages; $i++) {
$newoffset = $limit*($i-1);
if ($newoffset == $offset) {
print "$i&nbsp;\n";
}

else {
print "<a href=\"subcat.php?subcat=$subcat&CatSelect=$CatSelect&offset=$newoffset&limit=$resultlimit\">$i</a>&nbsp;\n";
}}

if the $a % $b get the reminder 0 which means $a will be mutiples of $b, then $a % $b = 0 and then if condition is false

else

the if condition is true.

[searain]

if (1) = if (true)

if (2) = if (true)

...

if (0) = if (false)
