[SOLVED] alphabetize

[Andrei]

Hi,

 

I am a total php neophyte. I hope you can help.

 

I am using the following code to display the content of a folder:

 

// Define the full path to your folder from root

$path = "/home/folder01";

 

// Open the folder

$dir_handle = @opendir($path) or die("Unable to open $path");

 

// Loop through the files

while ($file = readdir($dir_handle)) {

 

if($file == "." || $file == ".." || $file == "index.php" || $file == "error_log" || $file == ".htaccess" || $file == "getfile.php" )

 

continue;

echo "<a href=\"$file\">$file</a><br>";

 

}

 

// Close

closedir($dir_handle);

 

At the moment it displays the files randomly and I'd like to see the files alphabetized. Can anyone suggest how to do this?

 

Thank you so much for your help!

Just as a thought, you could put the files into an array and then use sort() to sort them alphabetically..?

[Andrei]

Not sure how to do that... What would that look like?

glob

 

<?php
$path = "/home/folder01/*";

$files = glob($path);

sort($files);
$badNames = array(".", "..", "index.php", "error_log", ".htaccess", "getfile.php");
foreach ($files as $filename) {
    if (!in_array($filename, $badNames)) {
          echo '<a href="' . $filename . '">' . $filename . '</a><br />';
    }
}
?>

 

Should do it for you.

Looks good

Thanks, that does indeed alphabetize the files, but it now displays the entire path to the file, as opposed to just the file name (previous code showed just the file name). Can that be remedied?

[premiso]

<?php
$path = "/home/folder01/*";

$files = glob($path);

sort($files);
$badNames = array(".", "..", "index.php", "error_log", ".htaccess", "getfile.php");
foreach ($files as $filename) {
    $filename = explode("/", $filename);
    $filename = end($filename);
    if (!in_array($filename, $badNames)) {
          echo '<a href="' . $filename . '">' . $filename . '</a><br />';
    }
}
?>

 

Should fix that.

Or use

 

    $filename = basename($filename);

 

instead of

 

    $filename = explode("/", $filename);
    $filename = end($filename);

 

Same outcome, just a bit shorter. And you can remove the dot and double dot from the $badNames array, since they don't appear when using glob().

Yep, a lot better than my way. My mind has just been shot the past few days. Thanks for pointing that out.

Wow thanks guys! I appreciate the amazingly fast responses! Works like a charm now!
