How does PHP handle errors like warnings and notices in code execution?

PHP handles errors like warnings and notices by displaying them to the user during code execution. To prevent these errors from being displayed and potentially leaking sensitive information, you can turn off error reporting or handle errors using try-catch blocks.

// Turn off error reporting
error_reporting(0);

// Handle errors using try-catch blocks
try {
    // Your code here
} catch (Exception $e) {
    echo "An error occurred: " . $e->getMessage();
}
