There is no way to *skip* optional function parameters in PHP. A respective RFC[1] had been declined. Passing NULL to an optional parameter does *not* necessarily use its default, but NULL, which in this case is converted to 0. So it is up to the userland developer to pass appropriate default values, e.g. in this case: function my_touch($url, $time, $atime=null) { return touch($url, $time, $atime ?? $time); } [1] <https://wiki.php.net/rfc/skipparams>
