I recently upgraded to PHP 5.3 and since then I get (sporadic) error messages which indicate Apache (or may be the cleaner of the session files) has no permissions to the folder where the sessions are stored.
This happens randomly and can't be reproduced with exact steps, which led me to guess it is the session cleaner.
Any one has experience with such errors?
I need to run a background PHP script on the server, but it clogs the pipe and chokes and server. How do I limit its resources and allow other tasks to run smoothly along with it.
Will incorporating usleep into the script help?

Hi!
I think most of us know about the infamous "Headers already sent" error in PHP. Can I check someway if headers already have been sent?
It would be really handy to do such, before going all out with trying to set some SESSION data or similar.
Thanks!
In my .htaccess file I need to turn on the following:
php_flag display_errors On
php_value error_reporting 2147483647
However I only want to do this if my IP is visiting the site.
Any ideas?
Something like...
if (ip == "x.x.x.x") {
php_flag display_errors On
php_value error_reporting 2147483647
}
Need to do this in .htaccess NOT in the PHP thanks!
Hi, I'm just wondering how I can retrieve a specific value (only 1 thing will be returned) from a database using php.
My query is
mysql_query("SELECT balance FROM users WHERE username = '". $this->username . "'")
I'm just looking for it to retrieve the data from that row so I can save it directory into a variable.
I have a php page that takes in a bunch of url parameters and sends out an email. I am trying to have this page call another web page using the same url parameters, after the mail is sent. If I do the following, will my email be sent reliably? Is a redirect what I really want to do?
Random code to send email...
header('Location: http://www.othersite.com/' + $_SERVER["REQUEST_URI"]);
We have an application that takes snapshots of certain web pages. It's quite tightly integrated into the code, so we're not ready to incorporate another library.
But we don't have a way of being able to calculate the web page height, so we end up taking snaps of 8000px height. Which is now proving troublesome when inserted into PDFs.
Is there a way to find the height of the webpage in PHP?
Hey!
Has anybody used a good obfuscator for PHP?, I've tried some but they dont work for very big projects. They can't handle variables that are included in one file and used in another, for instance.
Or do you have any other tricks for stopping the spread of your great code? :)
I'd like for my app to be able to tell if an image hasn't been viewed in the last 30 days and remove it (along with data in the DB associated with it). I know you can have PHP read and output the image dynamically but I've heard its quite taxing on the system. Is there a way to for me to track these hits even when the image is viewed directly? (would htaccess be able to do this?) Thanks in advance.

I need to round times down to the nearest quarter hour in PHP. The times are being pulled from a MySQL database from a datetime column and formatted like 2010-03-18 10:50:00.
Example:
10:50 needs to be 10:45
1:12 needs to be 1:00
3:28 needs to be 3:15
etc.
I'm assuming floor() is involved but not sure how to go about it.
Thanks
I've bounced around between different wrappers, my own, and using straight php mysql functions over the years but I'm sure there's a really good solution out there. What is it? :)
EDIT: Only needs to connect to MYSQL and it would be nice if it was lightweight.
