Well, the reason I stayed away from trying to use fgets for a single block
at a time were because of some of the comments from
http://php.net/manual/en/function.fgets.php
Anyways, an offtopic question if I may, I've tried making .htaccess
parseable by PHP using AddType and also attempting to do it by making
.htaccess a PHP-CGI file, to no avail. Is this something that is possible to
do with PHP? I have seen examples where mod_perl is used to generate
.htaccess files on the fly but nothing when it comes to PHP. If there is any
documentation in this are I would really be keen to see it.

Well, you'd want to do it one block at a time. But yes, if you are going
to be reading the files with PHP that's what you'll end up doing at some
level anyway. Otherwise look at Apache's mod_header and perhaps
dynamically generate the header information and write the appropriate
.htaccess files or something... But now we are well beyond having
anything to do with PHP.

> Ok, this is a pretty intersting one, and I'm not even sure if it's a bug
or just a memory limit thing. I am using a php wrapper for content files
(.jpg|.gif|.asf|.mov|.ram), as you can guess, the movie files can be pretty
large, upwards of 10MB, all getting read into memory, then spit back out.
Couple that with a site that gets 10K+ visits a day and the server is on its
knees with a load average of about 10 (when it gets to 25/30 things start
swapping and it will dies not long after that.)

a little while to sort through this one, I'm not even sure it's a bug
considering readfile is SUPPOSED to read a file into memory and spit it back
out. I dunno, for now I'm going to do some .htaccess tricks where I force
php to parse .htaccess files. If anyone has come across this or has any
insight on wrapping content in php files, please email me at
