If I run PHP from the folder with the script in: $ php -S 0:8080 index.php And then call http://localhost:8080/, the value for PHP_SELF is /index.php. If I run the script from a parent directory (or any other location that differs from the script), e.g.: $ php -S 0:8080 src/index.php The value for PHP_SELF when request http://localhost:8080/foo/bar will be /foo/bar. I'm not certain if this behaviour is intentional or not, but if it is, why is it this way? We noticed this issue because it breaks a lot of popular routing libraries as they strip the content of PHP_SELF from the variable they discern the path from, so it fails to route requests correctly. Test script: --------------- <?php echo $_SERVER['PHP_SELF']; Expected result: ---------------- Expect the PHP_SELF value to always provide a path to the script, not change between this and the web requested path. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=77253&edit=1
