php.ini为home / xyz写回家/ c？q = xyz

How to write php.ini such that

home/xyz/

means

home/c/index.php?q=xyz

Without creating xyz directory.

Try this

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^home/(.*)/?$ /home/c/index.php?q=$1 [L]

This should redirect all non existing files/directories in home/

EDIT: removing trailing slash
