How can the HTTP-Request be checked in the browser to identify potential issues with PHP code execution?

One way to identify potential issues with PHP code execution is by checking the HTTP-Request for any suspicious or unexpected input. This can help prevent injection attacks or other security vulnerabilities in your PHP code. By validating and sanitizing user input from the HTTP-Request, you can ensure that only safe and expected data is processed by your PHP code. 

// Validate and sanitize user input from the HTTP-Request
$user_input = $_POST['user_input']; // Assuming user input is passed via POST method

// Sanitize the user input to prevent injection attacks
$sanitized_input = filter_var($user_input, FILTER_SANITIZE_STRING);

// Validate the sanitized input to ensure it meets the expected format
if (preg_match('/^[a-zA-Z0-9\s]+$/', $sanitized_input)) {
    // Process the sanitized input
    // Your PHP code here
} else {
    // Handle invalid input error
    echo "Invalid input detected!";
}
