How can error reporting be effectively utilized in PHP to identify issues with code execution?

Error reporting in PHP can be effectively utilized by setting the error_reporting level to E_ALL to display all types of errors, warnings, and notices. This allows developers to identify issues with code execution and address them promptly. Additionally, using functions like error_log() or trigger_error() can help log errors to a file or output them for debugging purposes. 

// Set error reporting level to display all types of errors
error_reporting(E_ALL);

// Log errors to a file
ini_set('log_errors', 1);
ini_set('error_log', '/path/to/error.log');

// Example code snippet with intentional error
$var = 'hello';
echo $var2; // This will generate a "Notice: Undefined variable" error
