How can PHP developers effectively troubleshoot and debug their scripts for errors?

To effectively troubleshoot and debug PHP scripts for errors, developers can use tools like error reporting, logging, and debugging extensions like Xdebug. They can also use functions like var_dump() and print_r() to inspect variables and values during runtime. Additionally, breaking down the code into smaller parts and testing each part individually can help identify the source of the error. 

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

// Use var_dump() to inspect variables
$variable = "Hello World";
var_dump($variable);

// Use print_r() to print array values
$array = [1, 2, 3];
print_r($array);
