Those solutions will work, but the problem is actually the inability of the shell to start a process with that long of an argument list. (ARG_MAX bytes). The shell can process them, just not hand them off to another process via the argument vector.
echo * | xargs grep X-PHP-Script | more
will also work. (man xargs for more information)
Sorry to be a bit pedantic.
