What may be the reason why the php website cannot be accessed?

The reason why the php website cannot be accessed may be: 1. The php version is too low, such as [require php>5.3.0]. At this time, just change php to a higher version; 2. Database error. At this time It is necessary to check whether the database account and user name are correct; 3. The URL of the web page is invalid, and the program can be redeployed at this time.

There may be many reasons why the PHP website cannot be accessed. Let’s introduce several reasons and solutions:

(Recommended tutorial: php tutorial)

1. A 404 error occurs during access

A 404 error occurs during website access. The appearance of the HTTP 404 status code means that the web page pointed to by the link does not exist, that is, the original web page. The URL is invalid.

Possibility 1: The spatial structure file is deleted.

Possibility 2: The program is lost or deleted, just redeploy the program.

2. 500 error when accessing

The 500 error is usually caused by the website program file permissions problem.

Possibility 1: The file permissions are incorrect and need to be modified manually.

Possibility 2: It is caused by incorrect .htaccess file rules. Just rename, block or delete the file.

3. Prompt database error

The bridge between the program and the database is the database configuration file. When this problem occurs, you must first check whether the database configuration is correct. The host address is set to localhost. Check the database account and user name. Whether the password is correct can be checked by logging in. If it is incorrect, it can be reset and reconfigured.

4. When accessing the php version, the prompt information is different. For example, require php > 5.3.0 means that the current version is lower than 5.3.0. At this time, change to 5.3 or more. A higher version will do.
