What are the advantages of using error_reporting in PHP development to catch and address issues like undefined variables before they cause problems?

Using error_reporting in PHP development allows developers to catch and address issues like undefined variables before they cause problems by displaying warnings or errors. This helps in identifying and fixing potential bugs in the code early on, leading to more stable and reliable applications. 

// Enable error reporting to catch undefined variable issues
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Example code snippet with undefined variable
$variable = "Hello, World!";
echo $undefinedVariable; // This will trigger a notice due to undefined variable

// Output:
// Notice: Undefined variable: undefinedVariable in your_script.php on line X
