Using glob(), I want to find ALL files ending in .html, regardless of their case.

My code is case sensitive.

I want to find ALL these files:

      1.html
      2.HTML
      3.htML

foreach ( glob ( "*.hTmL") as $f) {
var_dump($f);
}

Yes, but can this be done more dynamically?  The extension type comes from a user-provided variable so this needs to support more than .html extensions.

$files = glob('my/dir/*');
$myFiles =  preg_grep('/\.html$/i', $files);

Or in case you haven't worked it out hankknight,, expanding on knight00's solution, you could add valid extensions like this:

    $files = glob('my/dir/*');
    $myFiles =  preg_grep('/\.html$|\.htm$|\.php|...etc.../i', $files);

BTW, sorry if this was meant to be a Knight family only, gathering.

Another alternative:
$ext = "hTmL";

$ext = "*." . preg_replace('/(\w)/e', "'[' . strtoupper($1) . strtolower($1) . ']'", $ext);

foreach (glob($ext) as $f)
{
	var_dump($f);
}

There is a deprecated function sql_regcase(). You can use this function. Check more from http://bd.php.net/sql_regcase


$pattern = sql_regcase("*.hTmL");
var_dump($pattern);

foreach ( glob( $pattern ) as $f) {
    var_dump($f);
}
