how to count total iteration for 2 loops?

newbie question

[macdar]

Hi,
I got stuck trying to count total iterations for two loops. My code is as follows:

for($i=1; $i<10; $i++){
echo $i;
for($j=1; $j<5; $j++){
echo $j;
}
}
it's gonna produce results as follows:
1 - 1,2,3,4
2 - 1,2,3,4
etc..

How to make this script output:
1,2,3,4,5,6,7..35,36?

Thanks.

please clarify, your question doesn't make sense. Are you trying to add the two loops together and have them display as one line? or are you trying to show the sum of the two loops?

I'm sorry about that. I tried to simplify that example as much as I could. I've got some sql queries implemented in that script. What I need to do is to get the sum of these iterations step by step.

for($i=1; $i<10; $i++){
echo $i;
for($j=1; $j<5; $j++){
//echo $j;
$q = "update table set wizard= '$wizard' where id = '$k';
}
}

where $k is 1,2,3,..36 (4*9).

Does it make sense now?

Thanks.

Is there any reason why

for($i=1; $i<37; $i++){
echo $i;
$q = "update table set wizard= '$wizard' where id = '$i';
}

wouldn't work?

[macdar]

Yes, that would be to easy..:)

The first loop takes results from DB..

the second one bases on a reglar expression function:

preg_match_all($what, $where, $search_results);

for($i = 0; $i < count($search_results[1]); $i++)
{
....
}

any ideas?

[ergophobe]

$count = 0;
for($i=1; $i<10; $i++)
{
for($j=1; $j<5; $j++)
{
$count++;
echo $count;
}
}

That should do it.

[macdar]

that's exactly what I meant, thanks ergophobe!

You're welcome. Mostly a matter of getting you to the right forum ;-)
