如何每月自动运行一个PHP脚本

Question

I have the php project for user can register and buy the hours to listen music or video, the not used of 50% hours have to rollover to next month, I wanted to automate this process when user complete one month I have to check their usage and process the rollover using php. I have following user details on DB, Signed-up date with time and usage and hours they purchased and used hours. I want to do it once in a month for each customer.

Is it possible using cron jobs? I don't have any idea to do this.

Answer 1

Not sure if this is the right approach but I've been running such kind of scripts when a user logs into his account.

For example.

You can do something like on successful login request by the user

if(date of buying hours has crossed the specified limit) /here you can check for expiry date/
{ // run your script here
     }
else{}

just a suggestion!

You don't need to update all of the records all at once. Just update it for the user who logs in. At the end, it will be updated for every user I think.

Answer 2

Short answer : Use Cron job.

Syntax and usage of how to use it is almost straight forward. Here's a cheat sheet .

Note: If you're on a shared host, some hosts don't allow you to use cron job.

Edit: What @Havenard suggested is correct. The below cron job will visit the url once at minute 00 of every hour:

0 * * * * wget http://www.mywebsite.com/some/link

Answer 3

yes this possible with Cron Job 1st Create your php file with your condition use update query then add this cron job file in your server Cron Job Section and select date when you want to run this file. in cron job just file your cronjobfile.php name , Date and time when this file run.
