List and display files in a folder

[kkhan5000]

Hello,

I am new to PHP and have put together the following code just by copying other examples from the web. Now I am stuck and would like to sort and display files alphabetically, and also filter what file type to display or not display. Thank you for your help.

}
}  
closedir($dh);

To sort them alphabetically, you'd have to create an array that holds the file name and location. Then sort() the array.

Thank you markusn00b, I will start learning about arrays.

Help!

I am not sure if I can figure this out on my own.

Read about arrays.

Thank you for the help with arrays. It is working now as far as the sorting is concerned, but it is now showing the sub directories. How do I filter out folders and file types. Here is what I have now:

<?php
$dirpath = ".";
$dh = opendir($dirpath);
while (false !== ($file = readdir($dh))) {
$fileList[] = trim($file);

//Don't list subdirectories
if (!is_dir("$dirpath/$file")){
sort ($fileList); // sort the file list in the array
}
}
reset ($fileList); // go back to the top of the array
while (list ($key, $file) = each ($fileList))
{
//Truncate the file extension and capitalize the first letter
echo "<a href='$dirpath/$file'>". htmlspecialchars(ucfirst(preg_replace('/\..*$/', '', $file))). "<br />";"</a>";


}
closedir($dh);
?>

<?php
...
//Don't list subdirectories
if (!is_dir("$dirpath/$file")){
     sort ($fileList); // sort the file list in the array
}
...
 

I'm no expert, but maybe where your code says "Don't list subdirectories" has something to do with it.

If you have any questions implementing that, let us know!

Thank you Dan,

I fixed the subdirectory problem by re-organizing the code. Now the only last thing left is to display only a certain type of files instead of everything the folder.

You could get the file extension and then check to see whether it's in an array of allowed extensions.

Thank you markusn00b ,

I think I got it to work somewhat by using "!is_file". Well, I have something now what I needed and I can use. However, during the process of learning php, my requirements have considerabley changed. I am not a coder, period, and would like to pay if needed to get the following done.

I would like to use all lower case file names, which are hyphenated or underscored like: "nice_day.php or nice-day.htm". And, I would like to display them as "Nice Day" in a web page or navigation bar. The goal is to drop an php/html document in a folder which dynamically shows up as a link in a navigation area of the web page.

Any advice would be greatly appreciated.
