How can error reporting be utilized to identify issues in PHP code, such as missing variables?

Error reporting in PHP can be utilized to identify issues like missing variables by enabling error reporting and displaying notices. By setting error_reporting to E_ALL and display_errors to On in the PHP configuration, PHP will display notices when variables are used without being defined. This can help developers identify and fix missing variable issues in their code. 

// Enable error reporting to display notices for missing variables
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Example code with a missing variable
$missingVariable = $undefinedVariable;
echo $missingVariable; // This will trigger a notice for using an undefined variable
