Backend DevelopmentPHP TutorialPHP user verification PHP+Ajax verification code to verify user login
One advantage of using AJAX to verify user login is that the jump page does not need to be refreshed. In addition, it is safer to use the verification code, so I wrote it down after a while. A total of three files are used:
yz.php: The PHP file that generates the verification code. The verification code will be in the SESSION for comparison and call during login
index.php: The HTML file for user login
loginCheck .php:File to verify user login
The following is analyzed one by one:
yz.php file
index.php: Note, do not take $_SESSION["VCODE"] in this file, otherwise it will If you take it a step later, the previous verification code will be displayed after refreshing. Just verify it in loginCheck.php. I hope that all the content will be helpful to everyone's study, and I also hope that everyone will support this site.
The above introduces the PHP user verification PHP+Ajax verification code to verify user login, including the content of PHP user verification. I hope it will be helpful to friends who are interested in PHP tutorials.
