A PHP warning can occur if the filename is a little less than (or equal to) \PHP_MAXPATHLEN [1] AND open_basedir [2] is configured (otherwise PHP will not throw this error [3]). By searching for the filename and appending a suffix (and also using the absolute path), we may exceed the limit. If the limit is exceeded, PHP throws a warning message [4] and Laravel aborts the execution of the code.
