How can PHP developers ensure the security of their source code while still allowing for transparency and collaboration?

PHP developers can ensure the security of their source code while still allowing for transparency and collaboration by implementing access controls, using encryption techniques, and regularly updating their software to patch any vulnerabilities. Additionally, developers can utilize secure coding practices, such as input validation and output sanitization, to prevent common security threats like SQL injection and cross-site scripting attacks. 

// Example of implementing access controls in PHP
if($user->isAdmin()) {
    // Allow access to sensitive code
    // Code here
} else {
    // Redirect unauthorized users
    header("Location: /unauthorized.php");
    exit();
}
