What are the potential pitfalls of relying on pre-made scripts from online repositories for website development in PHP?

Relying on pre-made scripts from online repositories for website development in PHP can lead to security vulnerabilities, compatibility issues with other scripts or frameworks, and limited customization options. To mitigate these risks, it is important to thoroughly review the code, ensure it is regularly updated, and customize it to fit the specific requirements of the project. 

// Example of customizing a pre-made script to enhance security
// Original pre-made script
function processForm($data) {
    // Process form data
}

// Customized script with added input validation
function processForm($data) {
    // Validate input data
    if (!isset($data['username']) || empty($data['username'])) {
        return false;
    }
    
    // Process form data
}
