PhP Script Help

Scipio

Hey all, new to the forums and semi-new to php. I am in a php class that goes through the coding aspect (leaving out safety etc unfortunately). Anyways I have an assignment with 1 particular thing giving me trouble:

Basically I have to make a page that shows the contents of a directory BUT if there are no text files in the folder I am supposed to kill the script. Mind you I am not on Php 5 yet due to instability.

Code I tried (for that specific part of the script) was:

$directory = dir("./courses/");

if(!(isset($directory[2]))){

        die("No files in directory");

}

To my knowledge $directory[0] would be taken up by "." and [1] would have ".." so I thought if [2] isn't set then there isnt an actual file in the directory. I am sure there must be a better way of doing this however as [2] could easily be taken up by a folder or image and still come out true that there is a txt file...

Look forward to some help on this, Thanks.

dir() returns an object not an array.

Read the manual for examples of how to use dir(). Check

www.php.net/manual/en/class.dir.php

Ahah I feel like such an idiot.

Ok so how could I go about doing this? Is there a way to put it into an array or perhaps a better way of checking for files in the directory?

Thanks for your answer btw.

Yes, read the manual. It even has an example:

<?php
$d = dir("/etc/php5");
echo "Handle: " . $d->handle . "\n";
echo "Path: " . $d->path . "\n";
while (false !== ($entry = $d->read())) {
echo $entry."\n";
}
$d->close();
?>

The above code echos the directory list to the page, Simply subsitute the echo statement with one that populates your array.

Ahah nevm about this question I fixed my newb q. Here is what I used to make up a form select list.

echo "<select name=\"course\">";

foreach($files as $file){

		if(eregi("^[a-z]+\.(txt)$", $file)){
			$filename = eregi_replace("\.(txt)","", $file);

                            echo "\n<option value=\"".$file."\">".$filename."</option>";

		}
   	 }

echo "\n</select>\n";
