This means that every single echo or print statement should use htmlspecialchars.Ī third example could be shell commands: If you are going to embed strings (such as arguments) to external commands, and call them with exec, then you must use escapeshellcmd and escapeshellarg.Īlso, a very compelling example is JSON.
For example, when you need to use a PHP variable in the SQL query, you have to use a prepared statement, that will take care of all the proper formatting/treatment.Īnother example is HTML: If you embed strings within HTML markup, you must escape it with htmlspecialchars. For your convenience, in most cases there is a dedicated tool for such an embedding. For example, in SQL, rules for strings, numbers and identifiers are all different. But you must understand that such rules could be too complicated to try to follow them all manually. What you should do, to avoid problems, is quite simple: whenever you embed a a piece of data within a foreign code, you must treat it according to the formatting rules of that code. Forget about filtering (or cleaning, or whatever people call it). PHP even has a (now deprecated) "feature", called magic-quotes, that builds on this idea. It's a common misconception that user input can be filtered. I have installed, ran and agreed to the Xcode licensing agreement.
