How can developers effectively troubleshoot PHP errors in specific lines of code?

To effectively troubleshoot PHP errors in specific lines of code, developers can use error reporting functions like error_reporting(E_ALL) and ini_set('display_errors', 1) to display errors on the screen. They can also use tools like Xdebug to step through the code line by line and identify the source of the error. Additionally, checking for syntax errors, missing semicolons, and typos in the code can help pinpoint the issue.

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Your PHP code here
// Make sure to check for syntax errors, missing semicolons, and typos
