I'm trying to graph Hard Drive utilization by partitions for a project I am working on. My goal is to allow user input of partitions of a server. From that point forward they can track changes in partition free space by entering the amount of free space on each partition at any given point of time. It can the be plotted out on a line graph. Here is some sample data: code:All I want is a good recommendation on a PHP graphing Class or package and maybe a push in the right direction.

chips posted:Have a look at jpgraph if you just want to generate images, but have you considered using either flash or javascript to do the plotting? Obviously it depends on what the client is and what it might support/be reasonable. I was looking at JPGraph and it looks like it might work. I also looked at PHP/SWF Charts which definitely looks much nicer but also more involved. I like the idea of displaying an image or a swf, and not having the browser draw the plots with javascript. This will all be web based obviously so IE / FF / Safari support is required.

I think I will need something different that can be included in a commercial application since this web app I am developing will probably be sold or subscription based.

standard posted:Does anyone know of a nice image serving type script? You could make one fairly easily if you are good with PHP. The problem isn't just serving images, you have to somehow tell the script where the image is stored on the server. What exactly are you trying to accomplish by not hard coding image paths?

standard posted:I'm competent but just can't be bothered to think through the security implications to be be honest. Most of the code I have was built for a purpose and not just for general image serving so it probably won't help you much. As for security, if you are trying to secure the images from prying eyes and only want to serve up images that the user is authorized to view that gets tricky but isn't too difficult. If a directory called images and just want to serve up images/hello.jpg but would prefer <img src="image.php?i=1" /> as opposed to <img src="images/hello.jpg" /> then that is easy.

Lets assume that we are in control of the size of files we are serving up with an image script. If that is true, is it still an issue or has it turned into a best practice scenario now?

Aturaten posted:I honestly forget if cpanel has the capability to edit the php.ini file, but you need to find it. After you do, look for: Don't do this!!! Instead use Easy Apache in WHM to add the Zip Extension under Exhaustive Options. If you don't use Easy Apache currently, then do whatever. If you modify things manually and then want to use Easy Apache later, things may not work as intended. I find it is best to either manually build and configure Apache and PHP or use Easy Apache, not both! http://twiki.cpanel.net/twiki/bin/view/EasyApache3/WebHome

Little Brittle posted:I need to download a text file every 10 minutes from a remote server. What is the best way to grab the file, while ensuring that the file is not being currently written? Right now, I'm grabbing the file via PHP FTP commands and processing it. you can use curl, it is probably the best option for using PHP to grab anything from a remote server. You could run something on the remote server to send you the file. This would allow you to lock it while sending.

You will at bare minimum want to validate user input via jQuery and then again via PHP. formtest.html code:php:<?php if (!empty($_POST['field'])) { echo "Form Submitted!"; echo "<pre>"; print_r($_POST); echo "</pre>"; } exit; ?> DarkLotus fucked around with this message at 21:01 on Mar 19, 2010 |
