如何使用PHP将图像插入数据库[关闭]

I'm wanting to allow a person to upload an image to the website that I'm making and I don't know how to do it. I know how to make the HTML form but after that, I don't have a clue. I have made the database and I'm wanting to do it in PHP.

Generally the best way to do this, is to upload the file to your server, and then store the path to it in the database.

File Upload: http://php.net/manual/en/features.file-upload.php

You need to choose a database, MySQL is a common and free option:

https://www.mysql.com/

As mentioned in comment below, (I haven't used it before but had a read and looks like a better option) https://mariadb.com/

PDO (recommended library to use with several types of databases): http://php.net/manual/en/book.pdo.php

Note that there are many security considerations when letting people upload files to your server: https://security.stackexchange.com/questions/32852/risks-of-a-php-image-upload-form/32853#32853

All in all, it may be longer than you think before your friend is uploading that file - but it will be worth it
