Over the past few days I have been running into some issues with my server crashing due to apache max connections issues. I am running my site off of a hosted Cloud VPS with 200GB of storage, 8192MB Memory, 8TB of transfer, Apache, MySQL, PHP5, and CentOS. I am afraid the issue doesn't necessarily lay in the configuration of Apache, but the way I have scripted the php on my site, the reason I am reaching out here. My site isn't your average website, it is more of a web-based customer management program. There are currently only 2 pages you can actually access via the url bar (signin.php and index.php). All other content is loaded via AJAX and JQuery processes (.load and $.getScript). All AJAX requests are pointed toward a single file called functions.php where a _POST parameter contains the function name and any additional _POST data required by the function. FOR EXAMPLE: AJAX Call: $.post('functions/functions.php',{func:'myFunctionName',ops:'whatever',a:'whatever',b:'whatever'},function(data){ DO WHATEVER I WANT WITH THE RETURN DATA HERE },"json"); PHP (functions.php) require 'dbcon.php'; include 'main_class.php'; include 'f_customerdetail.php'; include 'f_listoptions.php'; include 'f_route.php'; include 'f_useractions.php'; if (isset($_POST['func'])){ $userfunc = $_POST['func']; $funcops = $_POST['ops']; if ($funcops != ''){ $userfunc($funcops); }else{ $userfunc(); } } The functions.php file includes all of my other php files containing all of the functions. Each of the other files (f_customerdata.php, f_route.php, f_payroll.php, etc.) contains a number of functions which handle that specific genre of the site; this was more of an organization method I used to keep track of things. Now that you have a little background, I want to know if that is a toxic way to do things? If I currently have 100 people using the site and anytime they navigate it requests data from the functions.php file then that means there are going to be a ton of requests pointing to that single file, thus causing apache to crash; correct? There are multiple functions which use cURL to scrape data from another website as well. Therefore, a connection to the functions.php file may last in upwards of 5 minutes depending upon the function. A large issue as that all of the content on the site is completely dynamic; it is completely driven by getting data from the database and displaying it. Am I going about this correctly by having a single file handling all of the functions? Or, do I need to re-approach it by pointing the AJAX requests directly to the file containing the functions for that particular situation? I know this is a large question. I am completely self-taught, 4 years experience, and have developed a massive project over the last 6 months. I just want to be sure I am going about this the correct way. Thank you for your input, Josh
