File count - wrong number of files returned

ph3n0m

Just a quick fire question

Below is the code I am using to count the number of files inside a specific folder. However when I run the script it returns a completely different number then I expect.

E.G. in a folder that contains 5 html files, the script tells me that I have 8 files in the folder. I should point out that I am testing this all offline, on Windows running the Nusphere application

$dir = opendir("./sample_sites/$user2/");
while ($file[] = readdir($dir)) {}
$num_files = count ($file);
$numfile2 = $num_files;
for ($idx = 0; $idx < $num_files -1; ++$idx)
{
if ($idx < 2) {
echo (""); }

else {
echo "you have $numfile2 file(s) in your folder";

anyone have any ideas or solutions to my problem.

Maybe it's counting a starting position (I don't know why, but sometimes happen), . and ..

If you have this:
.
..
one.html
two.html
three.html
four.html
five.html

PHP may create this array:
(,.,..,one.html,two.html,three.html,four.html,five.html)

That's right the . .. are hidden fields. I used your code with slight mods and ran it on my system.

When I do counts like to return the totals from maybe a search it always seems to return one more record than it actually did. I'm sure it has to do with the for statement and a seasoned person may be able to help there but I usually just set a new variable when I print it out to set $idx=idx - 1. at the end of the loop. That's how I handle it.

I added an echo in there for you to print out the number it returns in the array before it loops through. The two print statements at the end I added so I could see the actual throughput (debugging steps).

Hope this helps. Oh, I also took out your $numfiles2 no need for it because you already have it in $numfiles. The "." in the opendir function just means the current directory that I stored the php file in.

$dir = opendir(".");
while ($file[] = readdir($dir)) {}
$num_files = count ($file);
//find out if there are any hidden files by printing out $num_files
echo "$num_files";
print "<table border = 0 valign=center width=100%>
";
for ($idx = 0; $idx < $num_files; $idx++)
{
if ($idx < 0)
echo ("");

else
print "<td>$file[$idx]</td>";
print "<td>you have $idx file(s) in your folder</td></tr>";
}
