Stripping off file extension from filename...

[cgm225]

If I have a variable $filename and it contains a filename, so something like:

 

$filename = "movie.avi";

 

How can I strip off the ".avi" so the variable only equals "movie"?

 

Thank you all in advance!

If the filename never contain a dot, you can do like so:

 

<?php
$file = "movie.avi";
list($filename, $ext) = explode('.', $file);
// $filename = movie
// $ext = avi
?>

 

If it DOES contain dots, the above will fail. Instead you could do this:

 

<?php
$file = 'my.movie.avi';
$arr = explode('.', $file);
$ext = array_pop($arr);
$filename = implode('.', $arr);
// $filename = my.movie
// $ext = avi
?>

<?php
$filename = 'something.somethingElse.ext';

$without_extension = preg_replace('/\.[a-z0-9]+$/i', '', $filename);
?>

It would be cheaper to use:

 

$name=substr($filename, 0, strrpos($filename, "."));

If you're using PHP v5.2 or greater, you can use the pathinfo() function with the PATHINFO_FILENAME constant:

<php
$filename = 'this.is.a.weird.file.name.longextension';
echo pathinfo($filename,PATHINFO_FILENAME);
?>

pathinfo is more expensive than both substr and strrpos combined, btw, as it looks up more than just the filename without the extension.

The OP asked how to do it, not which way was most efficient. What I gave was one more way to do what the OP was looking for.

It's a great way of doing it - I was simply pointing out a slight consideration one might want to be aware of I wasn't trying to be rude, and I apologise if I seemed that way.
