PHP Case Insensitive Version of file_exists()

Question

I\'m trying to think of the fastest way to implement a case insensitive file_exists function in PHP. Is my best bet to enumerate the file in the directory and do a strtolowe

Answer 1

//will resolve & print the real filename
$path = "CaseInsensitiveFiLENAME.eXt";
$dir  = "nameOfDirectory";

if ($handle = opendir($dir)) {
 while (false !== ($entry = readdir($handle))) {
     if (strtolower($path) == strtolower($entry)){
       echo $entry ;
    }}
    closedir($handle);
}
