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: $myArray = list_files([string], [string], [1], [0]);
echo result: list_files([string], [string], [1], [1]);
function list_files($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");
}
}
}
