Image Gallery PHP Loop Files Dynamic XML Tutorial
Learn how to render dynamic XML files for JavaScript or Flash Photo Gallery applications using PHP loops to show the most current data at all times.
This file reads a directory on its own to render the XML file, all you have to do it point it at a folder of images no matter how many are in it, and it will produce nice clean XML nodes for all of the images.

$xmlBody .= "<XML>"; // Start XMLBody output
// open specified directory using opendir() the function

// Create incremental counter variable if needed
$i = 0;
while ($file = readdir($dirHandle)) {
// if file is not a folder and if file name contains the string .jpg
if(!is_dir($file) && strpos($file, '.jpg')){
$i++; // increment $i by one each pass in the loop
$xmlBody .= '
<Picture>
<picNum>' . $i . '</picNum>
<picURL>' . $dir . '' . $file . '</picURL>
</Picture>';
} // close the if statement
} // End while loop
closedir($dirHandle); // close the open directory
$xmlBody .= "</XML>";
echo $xmlBody; // output the gallery data as XML file for flash
