readdir

[Anon]

Does anyone know if I can use the readir function to find certian files in a directory? For instance, if I search for all .gif files in one dir, how would I tell it to do that?

Uhmmmmmmanual!

Quote from the manual:

<?php
$handle=opendir('.');
echo "Directory handle: $handle\n";
echo "Files:\n";
while (($file = readdir($handle))!==false) {
echo "$file\n";
}
closedir($handle);
?>

Add a little IF statement and you're done.

I just don't understand what to put in the if statement. If I want all .gif files, do I put:

if ($file == "*.gif")

or is there something else?

allmost.
You cant do wildcard search on a string.
You need to compare the last 4 (yes 4, not 3, you must include the dot)
to what you are looking for ".gif"

if (substring($file,-4)==".gif")

When I do that I get this error:

Fatal error: Call to unsupported or undefined function substring() in /usr/home/php3/mail.php3 on line 71

Woops, in PHP it is called substr, not substring
sorry,
my mistake..

Hey cool, thanks. Now I have one more question (and thats it!! I promise!!! well... until I need help again that is) I allready tried it (so I know it dosne't work) is there a way to do that and find 2 diffrent file types? example:

if (substr($file,-4)==".gif" && substr($file,-4)==".txt") {
echo "$file";
}

I know that dosen't work cause I allready tried it.
