rename() help

ntlab

Ok.. I have racked my brain and searched every place that I can think of. I need help, please.

I need to rename a file that begins with the letters "uv" here is what I have. It works fine if I statically type the name of the file to replace the $fileName variables. However, this file changes daily but it always begins with the letters "uv".

$fileName=(uv);
if (file_exists("$fileName")) {
rename("$fileName", "$reportDirectory.txt");

}

How do I specify the file with a wildcard such as "uv*" and pass it to the rename function. Any help would be greatly appreciated.

hehe, I just used substr to check the first 2 letters of the file, then test and see if they equal UV... how about that? Ok anyways here is the script, you should be able to know what it means.. 🙂

$file = "uvtest.txt";
$length = strlen($file);
$firstLetters = substr($file, 0, 2);
if($firstLetters == "uv") {
echo "It begins with UV so can be renamed.<br>";
} else {
echo "Does not begin with UV.<Br>";
}

Thanks WD. That almost works... except I am passing a number of files to the function not just one file. Basically I am reading a directory. Like this:

<?php
$directoryObject = dir("c:\inetpub\wwwroot\test\");
while($fileName = $directoryObject->read())
if ($fileName != "." && $fileName != "..")
{
echo "$fileName<br>\n";
}
$directoryObject->close();
clearstatcache();

?>

I need to check the $fileName to see if it contains "uv" if it does then rename it to a different name such as "report032803.txt". Essentially it would need to select the ONE file from around thirty files in the directory that started with "uv" and that file would always be a different number (since it is a spooler file from an hp9000). Then rename the file. Thanks again for anyone who can help.

You can try this.. It will also rename it to report (then the time in seconds since the unix epoc... Jan 1, 1970)

so it'll always be different, look something like...

report23904234.txt
That should loop through all the files in the directory (change the directory I have in there...!

if ($handle = opendir('.')) {
    while (false !== ($file = readdir($handle))) { 
        if ($file != "." && $file != "..") { 
$length = strlen($file);
$firstLetters = substr($file, 0, 2);
if($firstLetters == "uv") {
$newName = "report" . time() . ".txt";
rename($file, $newName); 
} else {
echo "Does not begin with UV.<Br>";
}      

        } 
    }
    closedir($handle); 
}

That works perfectly! Thanks so much for your help WD. 😃
