How to write a regular expression "find everything up to the question mark"?

Question

PHP

It's been a long time and now I decided to master regular expressions.
I climbed a bunch of information and examples, but for the life of me I don’t understand how it is written “find everything before” or “find everything after”
here is an example:

$value = 'https://toster.ru/question/new?id=vasya';
$links = preg_replace('/*\?/','',$value);

An error pops up
