Read images in a directory (4 in a row)

[intenz]

Hello I've got a script that works like this:

1. It reads all filenames out of a folder.
2. It while loops echo "<img src...

I want to know how I can let the script only display 4 images in per row?

Can you help me with that?

Here's the script:

&lt;?php

$image = dir('myndir/babes/babevikunnar');

while($mynd = $image->read()) {
if ($mynd == '.' || $mynd == '..') {
continue;
}
if($mynd != "index.htm") {
echo "&lt;a href=skoda.php?skoda=myndir/babes/babevikunnar/$mynd><img src=myndir/babes/babevikunnar/$mynd width=106 height=161 border=0&gt;&lt;/a&gt;\n";
}
}
$image->close();

?&gt;

If you want to display 4 images per row, you have to print a linebreak after 4 images.

Forgive my sarcasm, but don't you think a simple counter could do the trick?
Maybe start at 1, then add 1 for each image you print untill the counter reaches 4, then you set the counter back to 1, print a linebreak and continue?

I just happened to write something like this yesterday.

Here is the script in action http://matt.illimited.net/phpstuff/thumbnails.php

Here is the source. http://matt.illimited.net/phpstuff/tnsrc.php

What I did was I just had a variable that was the number of pictures I wanted in a row. Then on each iteration of the loop I incremented a total variable. Then I just used the modulus (%) (I think that's what it's called) thingy. It will return the remainder if the numbers are divided. So when the remainder is 0 then the total must be a multiple of the pics per row variable therefore it's time to start a new row.

if (totalpics % pics_per_row == 0) start new row

I hope this is of some help.
