[Resolved] Convert a while loop to a for loop or combined

[fr8]

I have two loops that i want to combine together or use them both together.

The while loop grabs the info i want.

// Open a known directory, and proceed to read its contents
$fullpath = 'galleries/';
$dir = 'holidays/elf-sex/'; // pull from mysql
$newpath = $fullpath.$dir;

if ($handle = opendir($newpath)) {
  $i = 0;
        while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != ".." && $file != "thumbnails") {
          $i++;
}
        }
  echo "There are " . $i . " files in this directory";
  closedir($handle);
}

if ($dh = opendir($newpath)) {
    while (($file = readdir($dh)) !== false) {
      // Block files from being displayed
      if ($file != "." && $file != ".." && $file != "thumbnails") {

        // Display
        echo 'This is the file: '.$file.' and this is the location of it: '.$dir.'<BR>';
    }// IFELSE FILE BLOCKER
   }// WHILE LOOP
    closedir($dh);
} // IFELSE OPENDIR

And the for loop puts everything thing in a table that is so many collums wide.

This loop i used with a mysql queury

//set the number of columns
$columns = 2;

//we add this line because we need to know the number of rows

//changed this to a for loop so we can use the number of rows
for($i = 0; $i < $num_rows; $i++) {
    $myrow = mysql_fetch_array($result);
    if($i % $columns == 0) {
        //if there is no remainder, we want to start a new row
        echo "<TR>\n";
    }
        echo 'this is where everything goes.';

if(($i % $columns) == ($columns - 1) || ($i + 1) == $num_rows) {
    //if there is a remainder of 1, end the row
    //or if there is nothing left in our result set, end the row
    echo "</TR>\n";
}
}

1. have the first loop put its results into an array, and then have the second loop read from that array;

2. $num_rows = mysql_num_rows($result);
   for($i=0; $i<$num_rows; $i++)
   {
   	$myrow = mysql_fetch_array($result);
   	...
   }

I wont be pulling a list from the database. my list comes from the directory. the only thing that i get from the database is the directory location. Im not sure how to put a directory listing into an array.

I needed to varibles for my loop.

To get the two varibles that I needed for my forloop this is what i did.

    if ($dh = opendir($newpath)) {
        while (($file = readdir($dh)) !== false) {
          if ($file != "." && $file != ".." && $file != "thumbnails") {

            // Make Array
            $files[] = $file;
            //Count Files
            $i++;

    }
   }
}
