I have two variable:
$lang = hu
$image = image.jpg
How to replace image.jpg to image_hu.jpg in php? Maybe with str_replace? But how?

this method will work for any file type and with image names that have more than one period. (DEMO)
Code
<?php
echo merge('image.test.1234.gif', '_en');
function merge($file, $language){
$ext = pathinfo($file, PATHINFO_EXTENSION);
$filename = str_replace('.'.$ext, '', $file).$language.'.'.$ext;
return ($filename);
}
?>
Result
image.test.1234_en.gif

This would fail if for some reason the file name had an extra dot in it like:
recent.image.jpg. The result would be recent_hu.image.jpg

Sorry you must have caught me in between updates. Updated to work properly now.

this will fail if the filename has $ext inside of the name:
'image.gift.1234.gif'

@stevecomrie, Try this, fast and can correct to show it, stackoverflow.com/a/75505259/5049864
Using preg_replace would work well:
$new_str = preg_replace('/(\.[^.]+)$/', sprintf('%s$1', $lang), $image);

Note - this code will only work for JPGs. For a more universal method, try
explode().

@Duthcie432: Or you could just change the regexp from '/\.jpg$/' to '/\.[a-z0-9]+$/' and it will work for all file extensions.

Fair enough. What if the filename has more than one
. like image.test.png

I determine the filename and the extension, so the first example works for me. I edited the question: $lang is without the '_' character. I modified the first example, that is working, but what I need to modify, when I want to use the more universal version '/\.jpg$/' to '/\.[a-z0-9]+$/'

@Galen - again this only works for files with one
.. So in that respect it works just as well as accepted answer |
Another option would be to use the built in function pathinfo to separate the file extension from the filename.
$path_parts = pathinfo('image.jpg');
$final = $path_parts['filename'] . $lang . '.' . $path_parts['extension'];

I think this is actually a much more readable solution than any of the regex ones based ones.
I would use the following:
$new_str = preg_replace( '/^(.*?)\.(\w+)$/', '${1}$lang.${2}', $image );
That way your code would still work for JPG/gif/jpeg/PNG/etc
