Question

New to PHP…searched the manual, just don’t understand how to put it all together. I’m trying to go through a folder and display each html file as it’s contents…that part works. I can’t figure out how to change a div id incrementally.

This code works for displaying the what I want I just need unique id’s in my divs.

$dir = realpath('./path/to/folder/of_files/');
foreach (glob($dir .'/*.html') as $page){
   $div = file_get_contents($page);  
   echo ("<div class=\"interface\" id=\"ID_$id\">$div</div>");
}

Thanks in advance.

If $id is just some integer you can stick an $id++; somewhere…

$id = 1;
$dir = realpath('./path/to/folder/of_files/');

foreach (glob($dir .'/*.html') as $page){
   $div = file_get_contents($page);  
   echo ("<div class=\"interface\" id=\"ID_$id\">$div</div>");
   $id++;
}
