[RESOLVED] Start array at 1

[kbc1]

Hi all,

I am reading the contents of a folder and storeing the file names to an array as such:

[code=php]while (false !== ($filename = readdir($dh))) {
   $files[] = $filename;
}[/code]

When i print_r the values to the webpage, even though I only have 6 files in the folder, there are 8 elements in the array showing where the first 2 are empty.

How can I set the array to start at the 3 element?
Regards

You could unset them. Or, perhaps you can keep some data out of there in the first place - show us the array contents?

Are you sure the first two are empty, or do they contain '.' and '..'?

Contents are:
Array ( [0] => . [1] => .. [2] => Q1-5.gif [3] => Q11-15.gif [4] => Q16-20.gif [5] => Q21-25.gif [6] => Q26-28.gif [7] => Q6-10.gif )

Yep. What you are looking at are the references to the current and parent directories.

The solution is to check for them before inserting into the array.

while (false !== ($filename = readdir($dh))) {
	if ($filename != '.' && $filename != '..') {
		$files[] = $filename;
	}
}

To my rescue once again laserlight!
That worked a treat.
Many Thanks
