[PHP] HEAD method in PHP 4.1.2
Hello PHP world, I need to fetch headers via a HEAD request. This is doable via context options as of PHP 5.0.0, but the PHP on this server is 4.1.2. Upgrading PHP is not an option. Does anybody know a way to do this? I realize I can write my own HTTP client requests, but doing a good job with that a different thing. Thanks in advance. - Lucas Gonze -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Threading & PHP
One possibility is to have the code which first receives the request split it up into subrequests and do HTTP requests for the subrequests. Whether that makes sense depends on whether the overhead of an HTTP transaction is a big part of the execution time of the subrequests. - Lucas On Saturday, Jan 24, 2004, at 15:24 America/New_York, Galen wrote: Hi, This may be completely crazy, but let me tell you what I want to do: thread PHP. My server is a dual-processor 2 GHz machine, and it's not very loaded. I have a few tasks that are huge and lengthy and would benefit from being placed in their own "thread" if you will. This would serve to either accelerate the process by splitting it among CPUs or allow the process to continue "in the background" for a few seconds after all pages have been loaded. There are two areas where I'd use this: 1) To accelerate results in a relevancy ranking/fuzzy matching algorithm I have created, and although I've optimized the heck out of it, it can be slow when hundreds of thousands of items are thrown at it. It would be easy to split the array in half and run the algorithm on both halves, which would almost half processing time for returning results. 2) With image processing. When a user uploads an image to a few of my pages, the image is processed, re-compressed, and filed in the database or a file system. This can take several seconds, and I'd prefer that the user doesn't have to wait for the process to complete. How might I be able to make some PHP code run as a "thread" that would serve these purposes? -Galen -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] problem identifying $_SERVER['HTTP_REFERER']
First thing to do is figure out whether the problem is with the referrer
var or with your code. Try adding a logger to dump all environment vars
to a log file, then check it the next time one of these errors comes up.
good luck.

Re: [PHP] post variables
I can't think of a reason for this, so I would doublecheck your
assumptions. There is a $_SERVER variable to check the method.
You might want to put the php printenv.php page in place of your current
script to see what it says about the request method and POST variables.

[PHP] sending reply, the continuing
I have a situation where I want to send a cached result back then recalculate the cache. This is necessary because it takes a long time to generate a page. Is there a way for me to return what the browser needs, then terminate the connection without stopping my script?

Unfortunately that keeps the connection alive while the cache is being recalculated, so that even though the browser has everything it's going to get almost immediately, the throbber keeps going for quite a while, thereby freaking out my users. :( I could fork(), have the parent exit, and regenerate the cache in the child process, but pcntl_fork is not designed for a web server environment.* - Lucas * http://www.php.net/manual/en/ref.pcntl.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I thought about that but ended up not doing it for fear of zombies -- that was my interpretation of the warning in the documentation that CGI scripts shouldn't futz with process control. In the end the cleanest solution was to set up a cron job which fetches the cache regenerator. This was purely an issue of convenience. I implemented both the cron solution and the callback solution, and found that the version using the callback wasn't working. Obviously this meant a bug, but given that the solutions are roughly as good as one another I just stuck with the one that was quicker.

Won't that redirect through the browser?
