[SOLVED] Maintaining a counter variable!

[dai.hop]

Hello all,

 

Everytime I call this function the $counter variable goes back to zero. I would like to be able to call it three times and have the counter not reset back to zero.

 

Here is my code:

 

function create_items($orientation)
{
if (isset($counter))
{

} else
{
	$counter = 0;
}

# specify directory to be processed
$path = $_ENV['DOCUMENT_ROOT'] . '../../../images/ebay/canvas_xpress/products/';

# open the directory and save results
$directory = opendir($path);

# table start
echo '<table width="100%" border="0" cellpadding="0" cellspacing="0" bgcolor="#EDEDED">';

# output rows
while ($file = readdir($directory)) 
{
	# exclude the first two file entries
	if ($file == '.' || $file == '..')
	{

	} else
	{
		# acquire and output the thumbnail file
		$parts = explode("-", $file);
		$filename = $parts[0];
		$thumbnail = $parts[1];
		if ($thumbnail == 'thumbnail.jpg')
		{
			# acquire image size and set 
			list($width, $height) = getimagesize($path . $file);

			# determine image dimensions and set display variables accordingly
			switch ($orientation) 
			{
				case 'landscape':
					if ($height < $width)
					{
						begin_ouput('width="45" height="30"', $counter, $filename, $path, $file);
						$counter = $counter + 1;
					}
				break;

				case 'portrait':
					if ($height > $width)
					{
						begin_ouput('width="20" height="30"', $counter, $filename, $path, $file);
						$counter = $counter + 1;
					}
				break;

				case 'square':
					if ($height == $width)
					{
						begin_ouput('width="30" height="30"', $counter, $filename, $path, $file);
						$counter = $counter + 1;
					}
				break;
			}
		}
	}
}

# table end
echo '</table>';
}

function begin_ouput($attributes, $counter, $filename, $path, $file)
{
# 
$filename_shortened = strlen($filename) > 25 ? substr($filename, 0, 25) . '...' : $filename;

# begin output
echo '<tr class="table_row_hover" onclick="document.form.image_select[' . $counter . '].checked = true;"><td>' . '<input id="image_select" name="image_select" type="radio" value="' . $filename . '" />' . '</td><td>' . '<a href="' . $path . $filename . '-closeup.jpg' . '" target="_blank"><img src="' . $path . $file . '" ' . $attributes . ' hspace="5" vspace="8" border="0" class="border_grey_light" alt="Click for larger version"></img></a>' . '</td><td>' . $filename_shortened . '</td></tr>';
}

I'm sure theres a way to beat this but I just can't seem to come up with the answer!

 

Thanks for looking!
