I found many issues when handling external files with PHP.

I conjectured that PHP caches files and filenames internally, only 
flushing to disk on exit.

For example writing a file to disk didn't happen so that mysql could use 
it in a load file command unless it was copy()ed first.

unlink() for a file generated within PHP did work. But the same is not 
true of files outside of it that may not have write permission for 
whatever process spawned PHP..

My response to these issues has been to insert binary data using a 
hexadecimal number string, instead of load file, and to use the mysql 
database as a repository for all data, rather than the native OS file 
system.

Mysql at least has a single unique interface and will queue asynchronous 
requests, so that it always does what it says on the tin.

AS far as access to PDFS go, the approach I would take is to put them in 
a database too in a BLOB, and use a php script to serve them that 
authenticates the user (as identified by a cookie)  as valid, or returns 
an unauthorised access code.

writing PHP for authorised users is not a noobs easiest task, but its is 
one that needs to be mastered if you are going to make the distinction 
between authorised and public access.,
