How can error reporting in PHP help identify issues with variables containing special characters?

When variables containing special characters are not properly handled in PHP, it can lead to errors such as unexpected behavior or syntax issues in the code. To identify and address these problems, error reporting in PHP can be used to display warnings or notices when special characters are encountered in variables. This can help developers pinpoint the source of the issue and make necessary adjustments to handle special characters correctly. 

// Enable error reporting to display warnings for special characters in variables
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Example variable containing special characters
$specialVar = "Hello, world! This is a special character: ©";

// Use htmlspecialchars function to properly handle special characters
$cleanVar = htmlspecialchars($specialVar);

// Output the sanitized variable
echo $cleanVar;
