Wrong SCRIPT_FILENAME & PHP_SELF in Apache 2.4.26

With Apache 2.4.26 using php-fpm 7.1.6, $_SERVER['SCRIPT_FILENAME'] (and $_SERVER['PHP_SELF']) is incorrect on a folder:

Apache 2.4.26:

/index.php

Apache 2.4.25:

/myfolder/index.php

What is wrong?

Solution

  • I fixed it in apache config with this new config directive :

    ProxyFCGIBackendType GENERIC

    In global configuration before the SetHandler directive. Default is FPM, but it's not correct with some php-fpm configuration (SetHandler and socket).

    With this bug all $_SERVER['SCRIPT_FILENAME'] and $_SERVER['PHP_SELF'] Apache vars ($_SERVER) (injected from php-fpm) are wrong, they don't have the path!

    ProxyFCGIBackendType is default to FPM but it's wrong for many configuration. Apache httpd should add GENERIC as default to don't break websites.

    See: https://httpd.apache.org/docs/2.4/en/mod/mod_proxy_fcgi.html#proxyfcgibackendtype
