PHP is a server-side scripting language that tells the server what to send to your web browser. Using custom PHP, web developers can also make HTML CSS modifications that are sent to the web browser. While PHP is a relatively safe and easy scripting language, there are some tips and tricks web developers should adhere to in order to avoid server crashes and security issues.
Custom PHP Coding “Don’ts”
Don’t Create an Infinite Loop
Without the proper PHP configuration, creating an infinite loop might crash the server. To avoid this, carefully read over your code and test on a development server.
Don’t Use PHP Short Tags
While there are some advantages to using PHP short tags, using them also presents a big risk. These may not be enabled on your server, meaning errors may be printed on the screen, or the code may be displayed to users (which can pose a big security problem).
