How can developers effectively troubleshoot and debug browser-specific issues in PHP applications?

When troubleshooting browser-specific issues in PHP applications, developers can use conditional statements to detect the user's browser and apply specific fixes or workarounds. By checking the user agent string provided by the browser, developers can identify the browser being used and adjust the code accordingly. This can help address compatibility issues and ensure the application functions correctly across different browsers. 

$user_agent = $_SERVER['HTTP_USER_AGENT'];

if (strpos($user_agent, 'Chrome') !== false) {
    // Code specific to Google Chrome
} elseif (strpos($user_agent, 'Firefox') !== false) {
    // Code specific to Mozilla Firefox
} elseif (strpos($user_agent, 'Safari') !== false) {
    // Code specific to Safari
} else {
    // Default code for other browsers
}
