Sanitizing user input is an important step in building secure web applications to prevent attacks such as SQL injection, cross-site scripting (XSS), and others. In PHP, you can use various functions and techniques to sanitize input variables, including filter_input(), htmlspecialchars(), mysqli_real_escape_string(), and others. When it comes to sanitizing GET variables, you should be especially careful because they can be easily manipulated by the user. Here are some best practices for sanitizing GET variables in PHP: Always check that the variable is set and not empty before using it. You can use isset() and empty() functions to check this. Use filter_input() function to sanitize the input. For example, you can use FILTER_SANITIZE_STRING filter to remove any tags and characters that are not allowed in a string. If you are using the input in a database query, use prepared statements and parameterized queries to prevent SQL injection attacks. Escape any special characters that may be in the input using htmlspecialchars() or mysqli_real_escape_string() functions before displaying the output. Here is an example of sanitizing a GET variable using filter_input() function: This code filters the id variable, which is expected to contain an integer value, and removes any characters that are not allowed in an integer. You can then use this sanitized value in your code without worrying about malicious input.
