How to remove a certain combination of characters from the end of a string?

Question

PHP

Good evening.
I'm trying to figure out the preg_replace construct in order to remove a combination of characters and / or numbers at the end of the line, but I'm dumb and don't come out right away.
I thought so, but it doesn't work:

$image_name = preg_replace("/_int[-\d]$/",$image_name);

There are lines that always end with the word _int or _int-01 or _int01
Help with the expression to delete this expression, please.
And it would be great if you could also find out that there is such a replacement and return true or false. Thanks

Answer 1

$image_name = preg_replace("/_int-?\d*$/", "", $image_name, -1, $count);

$count will contain the number of replacements made
