What are common syntax errors to watch out for when using PHP echo statements?

Common syntax errors to watch out for when using PHP echo statements include missing semicolons at the end of the statement, mismatched quotes, and forgetting to concatenate variables within the echo statement. To solve these issues, always ensure that each echo statement ends with a semicolon, use consistent quotes (single or double) around the echoed content, and properly concatenate variables with the "." operator.

// Example of correct syntax with semicolon and proper concatenation
$name = "John";
echo "Hello, " . $name . "!";
