What are the common uses of BB Code in PHP forums and what potential pitfalls should users be aware of when implementing it?

One common use of BB Code in PHP forums is to allow users to format their posts with features such as bold text, italic text, hyperlinks, and images. However, users should be aware of potential security risks when implementing BB Code, such as allowing malicious code to be executed. To mitigate these risks, it is important to sanitize user input and validate the BB Code before processing it. 

// Example of sanitizing user input before processing BB Code
$bbCode = sanitizeInput($_POST['bbCode']);
$processedText = processBBCode($bbCode);

function sanitizeInput($input) {
    // Implement your sanitization logic here
}

function processBBCode($bbCode) {
    // Implement your BB Code processing logic here
}
