Sorting directory listing

[peters1977]

I have quite a few PHP web pages that list directory files of a Unix system with opendir and readdir functions. Everything works fine, but the files are displayed in the order they were created.

I would like to sort them alphabetically. What should I do?
Here's the code for the page:

$current_dir = "/export/home/apache/htdocs/security";
$dir = opendir($current_dir);
if ($current_dir = opendir('.')) {
while (false !== ($file = readdir($dir))) {
if ($file != "." && $file != "..") {
print ("<p><a href=security/$file>$file</a></p>\n");
}
}
closedir($dir);
}

Thanks

Try this...

$fileList = array();
$current_dir = "/export/home/apache/htdocs/security"; 
$dir = opendir($current_dir); 
if ($current_dir = opendir('.')) { 
while (false !== ($file = readdir($dir))) { 
if ($file != "." && $file != "..") { 
$fileList[] = $file;
} 
} 
closedir($dir); 
} 

sort($fileList);
reset($fileList);
for($i=0;$i<sizeof($fileList);$i++) {
echo "$fileList[$i]<br>";
}

Try that.

Your script worked really well. I have to start reading more about arrays, and practice more.

Thank you very much for you help.

No problem. If you need anything else, just ask... 🙂
