How to Remove Extension from String (Only Real Extension!)

How to remove extension from string (only real extension!)

Try this one:

$withoutExt = preg_replace('/\\.[^.\\s]{3,4}$/', '', $filename);

So, this matches a dot followed by three or four characters which are not a dot or a space. The "3 or 4" rule should probably be relaxed, since there are plenty of file extensions which are shorter or longer.

How to trim a file extension from a String in JavaScript?

If you know the length of the extension, you can use x.slice(0, -4) (where 4 is the three characters of the extension and the dot).

If you don't know the length @John Hartsock regex would be the right approach.

If you'd rather not use regular expressions, you can try this (less performant):

filename.split('.').slice(0, -1).join('.')

Note that it will fail on files without extension.

remove extension from file

There are a few ways to do it, but i think one of the quicker ways is the following

// $filename has the file name you have under the picture
$temp = explode('.', $filename);
$ext  = array_pop($temp);
$name = implode('.', $temp);

Another solution is this. I haven't tested it, but it looks like it should work for multiple periods in a filename

$name = substr($filename, 0, (strlen($filename))-(strlen(strrchr($filename, '.'))));

Also:

$info = pathinfo($filename);
$name = $info['filename'];
$ext  = $info['extension'];

// Shorter
$name = pathinfo($file, PATHINFO_FILENAME);

// Or in PHP 5.4
$name = pathinfo($filename)['filename'];

In all of these, $name contains the filename without the extension

remove file extension from twig variable

you can try this :

{{ video | replace({('.' ~ video | split('.')[video | split('.')|length - 1]): ""})}}

Look fiddle

Remove domain extension

$subject = 'just-a.domain.com';
$result = preg_split('/(?=\.[^.]+$)/', $subject);

This produces the following array

$result[0] == 'just-a.domain';
$result[1] == '.com';

php regex replace caracters from filename until extension

You can try with pathinfo function to separate extension from filename and replace unwanted character only in base filename. After everything, just merge those parts:

$filename = '23$%^&.234234.%^.234$%$#)(.^$.png';
$pathinfo = pathinfo($filename);
$filename = implode('.', array(
  preg_replace('/[^A-Za-z0-9_\-\(\) ]/', '-', $pathinfo['filename']),
  $pathinfo['extension']
));

var_dump($filename);

Output:

string '23-----234234----234----)(---.png' (length=33)

Remove file extension from a file name string

I used the below, less code

string fileName = "C:\file.docx";
MessageBox.Show(Path.Combine(Path.GetDirectoryName(fileName),Path.GetFileNameWithoutExtension(fileName)));

Output will be

C:\file
