[RESOLVED] Read Directory readdir

transfield

Hello,
I want to read all the files in a folder & display them in a drop down menu. I'm using the code below & it works fine. I now want the file names to be sorted ascending before it is displayed in the drop down menu. How do I do that? Thank you very much for your help.

<select size="1" name="project">
<?php
if ($handle = opendir('/path/to/my/files/here/')) {
while (false !== ($file = readdir($handle))) {
 if ($file != "." && $file != "..") {
 echo "$file\n";
 echo '<option value="$file\n"</option>';
 }
}
closedir($handle);
}
?>
</select>

load everything into an array, then use natcasesort(), then loop through the array to create the options.

<select size="1" name="project">
<?php
// Initialize the array that will hold the
// file names
$files = array();

if ($handle = @opendir('/path/to/my/files/here/')) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {

// Add the file (if it is a file) to the array
$files[] = $file;
}
}
closedir($handle);

// If we have items in the array, sort the files naturally
if(count($files) > 0) natcasesort($files);

// Loop through the sorted array and
// print out the files
foreach($files as $output){
echo "$output\n";
echo '<option value="$output\n"</option>';
}
}
?>
</select>

I got bored so I wrote the code for you 😉

[edit] I made an edit for error checking.
