Getting weird error after update #24547
Description
Description
The following code:
<?php/*
Top index for sites.
*/?>Resulted in this output:
Fatal error: Uncaught Error: Undefined constant "php" in .../index.php:1 Stack trace: #0 {main} thrown in /var/.../index.php on line 1
But I expected this output instead:
[Empty]
I think this is crushing PHP because I'm not getting error reports in logs too.

Add a space after "php", this is not a bug in PHP.
