During php mysql application development, one must take care of the fact that he/she should not trust the user input. In case you are expecting an integer call intval() (or use cast) or in case you do not expect a username to have a dash (-) in it, you should check it with strstr() and prompt the user that the username is not valid.
Another you should ensure during php web development is that you should never use user inputs directly into SQL queries. Also, in SQL queries, never put integers in quotes.
Next, escaping the output is important as it protects your website or application from Cross Site Scripting (XSS) attacks.
While you are uploading a file, make sure that you validate the file mime type. In case you are expecting images, ensure that the file received is an image. It might be a Php script that can bring unimagined damages to both your website as well as its servers.

Giving the database users enough permission is also important for secured php web development. In case a database user is never going to drop tables, then while creating that user don't give it drop table permissions. Just select, update, delete and insert is enough.
Never allow hosts other than Localhost to connect with your database. In case it is required, add that particular host or IP as necessary. It is very crucial to remember that not everyone should connect to your database server.
Use Php extensions to make sure that no one is able to hack or change the passwords or other confidential information of your website.
