get file extention from url

[dualzNZ]

Hi all

i am a bit stuck lol
I am trying to get the file extention from a url say
yoursite.com/file.zip

in the data base the full link will be there, i am looking for a function that will take the full url
take ".zip" and then will output "(file type = ZIP )"

some help would be great

cheers

These functions seem to be along the line of what you're looking for:

• strrpos
  Find the position of the last occurrence of a substring in a string
• substr
  Return part of a string

So, you could use strpos to find where the last . character occurs in the string example.org/some_file.zip, and then use substr to get the part of the string that comes after that character (which would be zip in this case).

Hope that helps!

Hy
You can try with explode() function.
Example:

$str = 'yoursite.com/file.zip';
$ext = end(explode('.', $str));
echo 'file type = '. strtoupper($ext);     // file type = ZIP

The function you need is pathinfo:

$bits = pathinfo('/path/file.zip');
echo $bits['extension'];

So for your case:

$bits = pathinfo($url);
echo "file type = " .strtoupper($bits['extension']);
