How can PHP developers effectively troubleshoot and resolve errors in their code, as demonstrated in the forum thread?

Issue: To effectively troubleshoot and resolve errors in PHP code, developers can utilize error reporting functions like error_reporting() and ini_set('display_errors', 1) to display errors on the screen. Additionally, using tools like var_dump() and print_r() can help in debugging and identifying issues within the code. Code Snippet:

// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Sample code with error
$number = 'abc';
$result = $number * 2;

// Display error message
var_dump($result);
