Could reproduce. With safe mode, files which are handled by stream
wrappers are checked against the filesystem. This is wrong.

You apply the patch using the command patch when you build PHP from the
sourcecode. If you've never done this before I cannot recommend that you
do this for something like PHP.
If you still go ahead, download the PHP sourcecode, extract it and read
the files (README and INSTALL). Check documentation for using the patch
command (man patch). in general you save the patch to a file (lets call
it safemode.patch) then you simply run "patch main/safe_mode.c <
safemode.patch" in the folder where you unpacked the source
