I made this function to search and/or display files by extension or for a string occurance in the filename. Any comments or enhancements are welcome offcourse. I'll update this function soon.

usage: list_files([string], [string], [int 1 | 0], [int 1 | 0]);

search for extension: list_files([string], [string], [0], [int 1 | 0]);
returns array: $myArray = list_files([string], [string], [0], [0]);
echo result: list_files([string], [string], [0], [1]);

search for string occurance: list_files([string], [string], [1], [int 1 | 0]);
returns array: $myArray = list_files([string], [string], [1], [0]);
echo result: list_files([string], [string], [1], [1]);

<?php

function list_files($directory, $stringSearch, $searchHandler, $outputHandler) {
$errorHandler = false;
$result = array();
if (!
$directoryHandler = @opendir ($directory)) {
  echo (
"<pre>\nerror: directory \"$directory\" doesn't exist!\n</pre>\n");
return
$errorHandler = true;
}
if (
$searchHandler === 0) {
  while (
false !== ($fileName = @readdir ($directoryHandler))) {
   if(@
substr ($fileName, - @strlen ($stringSearch)) === $stringSearch) {
   @
array_push ($result, $fileName);
   }
  }
}
if (
$searchHandler === 1) {
  while(
false !== ($fileName = @readdir ($directoryHandler))) {
   if(@
substr_count ($fileName, $stringSearch) > 0) {
   @
array_push ($result, $fileName);
   }
  }
}
if ((
$errorHandler === true) &&  (@count ($result) === 0)) {
  echo (
"<pre>\nerror: no filetype \"$fileExtension\" found!\n</pre>\n");
}
else {
 
sort ($result);
  if (
$outputHandler === 0) {
   return
$result;
  }
  if (
$outputHandler === 1) {
   echo (
"<pre>\n");
   
print_r ($result);
   echo (
"</pre>\n");
  }
}
}

?>
