is what I suggested - not date(‘M’) and not adding may before the .php
date(‘F’) - will currently return ‘April’ then strtolower converts it to ‘april’ to which the concatenation makes it ‘april.php’. Tomorrow you’d get ‘may.php’;
strtolower(date(‘M’)).‘may.php’ - currently gives ‘aprmay.php’ and tomorrow it will give ‘maymay.php’
