Php and jQuery are used to implement the "TOP" and "step on" voting functions. phpjquery When we browse a webpage and want to agree or disagree with the content of the webpage, such as the opinions in articles and comments, we can click "TOP" and "step on" on the webpage to vote. The entire interaction process can be implemented asynchronously using ajax to improve user experience. We must first prepare the mysql DATA table required to run the entire instance. Two tables are required for the ins

default "0" value for us to do. Another useful example is a sliced hash table. Adding data to an empty slice will request a new slice so append data in a tiled map takes only one row, and you don't need to check if the key exists. In the example below, the slice is used to hold the value of the person type, each man has a name field and a slice, and this example creates a hash table that associates each item with a slice of what he likes.

Problem descriptionThis data needs to be ranked based on the statistical values of certain types of data over a dynamic time period. For example, the results are calculated every hour, based on a post that likes to rank in the last 24 hours. The following descriptions are for this example.Solution IdeasIn response to this problem, my first reaction was to go directly through MySQLA data table records the behavior of each statistic value change for all

, which defaults to 127.0.0.1: 9000. That is, it listens to data requests on port 9000 and then parses the requests and returns them to the request end.This is consistent with the FastCGI idea we introduced earlier. The HTTPServer server and the FastCGI mode PHP parser are separated (here is the PHP-FPM), when the HTTPServer encounters a PHP request, it will be passed to the PHP-FPM, the latter parses and r

, it is always a timeout. No matter how long the request time and script run time you will not be able to return data, such as file_get_contents ('HTTP: // localhost/phpinfo. php '). However, when you try to request static files such as html, there is no problem at all. Why ?! First, we know that when file_get_contents/curl/fopen opens an http request based on TCP/IP, the request data is sent to nginx, while nginx delegates php-cgi (fastcgi) to process the php file, generally, fastcgi will immed
