Question

I have the following PHP code that scans a directory and sub folders and lists all the PHP files in iframes.
I want to include all the PHP files from the directory except one, any instance of ‘index.php’.

I’ve tried adding:

 if ($file != "." && $file != ".." && $file != 'index.php')

But it doesn’t work.
Here’s the full code:

<?php
$iterator = new RecursiveDirectoryIterator('work/');

foreach( new RecursiveIteratorIterator($iterator) as $filename => $cur) {
$file_info = pathinfo($filename);

if($file_info['extension'] === 'php') {
    if ($file != "." && $file != ".." && $file != 'index.php')

    echo 
  "<iframe width=420 height=150 frameborder=1 src='$filename'></iframe>";
}
}

?>

Thanks!

When you are doing it the iteratorish way, you might as well also use a filtering iterator. RegexIterator in particular can be useful, and avoid a few if checks in your case.

 $iterator = new RecursiveDirectoryIterator('work/');
 $iterator = new RecursiveIteratorIterator($iterator) 
 $iterator = new RegexIterator($iterator, "~(?<![/\\\\]index)\.php$~");
 foreach ($iterator as $filename=>$cur) {
     print "$filename<br>";
 }

I think testing for . and .. is redundant.
