[SOLVED] Get extension code -> file has two extensions ???

[doa24uk]

Hi guys,

 

 

I am currently using this code to split the extension from a file, this is working fine.

 

However my file has 2 extensions & I want to return them both

 

eg. filename.ext1.ext2

 

The code currently spits out

 

.ext2

 

And I need it to spit out

 

.ext1.ext2

 

//This function separates the extension from the rest of the file name and returns it
function findexts ($filename)
{
$filename = strtolower($filename) ;
$exts = split("[/\\.]", $filename) ;
$n = count($exts)-1;
$exts = $exts[$n];
return $exts;

 

 

If it matters, both extensions will always be the same length (and same length as each other...

 

eg. -> .mp3.txt

 

Thanks in advance for the help!

function findexts ($filename)
{
$filename = strtolower($filename) ;
$exts = split("[/\\.]", $filename) ;
$n = count($exts)-2;
$exts = $exts[$n];
$n2 = count($exts)-1;
$exts2 = $exts[$n2];
return $exts.$exts2;

Something liek that?

This is nearly working but unfortunately it's breaking the rest of the script because I'm not sure what variables to change further on in the script....

 

Here's the full script

 

 

//This function separates the extension from the rest of the file name and returns it
function findexts ($filename)
{
$filename = strtolower($filename) ;
$exts = split("[/\\.]", $filename) ;
$n = count($exts)-2;
$exts = $exts[$n];
$n2 = count($exts)-1;
$exts2 = $exts[$n2];
return $exts.$exts2;
}

//This applies the function to our file
$ext = findexts ($_FILES['uploaded']['name']) ; 

    //This line assigns a random number to a variable. You could also use a timestamp here if you prefer.
    $ran = rand () ;

    //This takes the random number (or timestamp) you generated and adds a . on the end, so it is ready of the file extension to be appended.
    $ran2 = $ran.".";

    //This assigns the subdirectory you want to save into... make sure it exists!
    $target = "directory/";

    //This combines the directory, the random file name, and the extension
    $target = $target . $ran2.$ext; 
    
    if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target))
{
echo "Congratulations - File upload Successful!<br><br><h2>File Links</h2>http://mysite.com/directory/directory2/".$ran2.$ext."some text after the link<br>";
}
else
{
echo "Oops! There was a problem uploading your file, please try again.";
}

How is it breaking your script? The function should only affect the filename of the moved file.

jackpf's function doesn't work as expected because the $exts array is reset. It can also be written much simpler:

 

function findexts($filename) {
$parts = explode('.', strtolower($filename));
list($b, $a) = array_reverse($parts);
return "$a.$b";
}

Should fit with the rest of your script as far as I can see.

Brilliant, that's working now. Many thanks!

Or:

$filename = 'hello.world.foo.bar.test';
preg_match('#((?:\.[^.]+){1,2})$#', $filename, $matches);
$ext = $matches[1]; // .bar.test
