Count # of files in a directory

[usbworkshop]

How do you use PHP4 to count # of files in a directory?

Thanks...

$dir = dir("pathtodir");
while($file = $dir->read()) {
if (($file != ".") && ($file != "..")) {
$filelist[] = $file;
}
}

print count($filelist);

Thanks...what do I put in pathtodir?

I want the program to check for the number of files found in http://www.domain.com/hardware/images/samples/$id

YOU will need to the actual physical path not the http path but the server path for instance if your dir was locate at /home/www/html/stuff/

$dir = dir("/home/www/html/stuff/");

Thanks...

The code given seems to have some problems when the directory doesn't exist. How can I check to see if a directory exist? This way, I won't run into any problems with the codes.

THanks.

You can do this:

if(!$dir) {
echo "Error: cannot read directory"; exit;
}

Thanks I got it working.

Or you can use
$d = "/pat/to/some/dir/";
if (is_dir($d)) {
$dir = dir($d);
while($file = $dir->read()) {
if (($file != ".") && ($file != "..")) {
$filelist[] = $file;
}
}

print count($filelist);
}
else {
print "the directory ". $d ." does not exist";
}
