What are the common mistakes that developers make when using echo statements in PHP, and how can these mistakes be avoided to prevent blank pages or incorrect output?

Common mistakes when using echo statements in PHP include forgetting to enclose variables in quotes, using echo inside HTML tags without proper concatenation, and not properly escaping special characters. To avoid these mistakes and prevent blank pages or incorrect output, always enclose variables in quotes, use concatenation when echoing inside HTML tags, and escape special characters using htmlspecialchars(). 

// Incorrect way without proper concatenation
$name = "John";
echo "<h1>Hello, $name!</h1>"; // Incorrect

// Correct way with proper concatenation
$name = "John";
echo "<h1>Hello, " . $name . "!</h1>"; // Correct
