Run controller method in background |
[eluser]Unknown[/eluser]
I'll start with what my program does. The index function of controller takes an array of URLs and keywords and stores them in DB. Now the crawlLink method with take all the keywords and URLs. The URLs are searched for all the keywords and the sublinks of all the URLs are generated and again stored in DB which are also searched for the keywords. Keywords are searched in each link using search method. The sublinks are extracted from all the URLs using extract_links function. search and extract_links both have a method called get_web_page which takes the complete content of the page using cURL. get_web_page is used once in search function to get content of web page so that keywords can be extracted from it. It is also used in extract_links function to extract links with valid page content. Now crawlLink calls search function twice. Once to extract keywords from domain links and second time to extract keywords from sublinks. Hence, get_web_page is called thrice. It approximately takes 5 mins to get contents of around 150 links. And it is called thrice so it takes 15 minutes of processing time. During that duration nothing can be done. Thus, I want to run this process in background and show its status while processing. extract_links and get_web_page are included in the controller using include_once. The get_web_page function is as follows: Code: function get_web_page( $url ) I read about so many ways to run function in background that now I am in a dilemma about which approach to adopt. I read about exec, pcntl_fork, Gearman and other but all need CLI which I don't want to use. I tried installing Gearman with Cygwin but got stuck in Gearman installation as it cannot find libevent. I've installed libevent separately but still it doesn't work. And Gearman needs CLI so dropped it. I don't want to use CRON also. I just want to know which approach will be best in my scenario. I am using PHP 5.3.8 | Codeigniter 2.1.3 | Apache 2.2.21 | MySQL 5.5.16 | Windows 7 64 bit EDIT: I need to run Code: localhost/codeigniter/index.php/controller/method |
