How can using single quotes instead of double quotes in PHP strings help prevent syntax errors?

Using single quotes instead of double quotes in PHP strings can help prevent syntax errors because variables inside single quotes are not parsed, meaning they are treated as literal strings. This can be useful when dealing with strings that contain special characters or variables that you don't want to be evaluated. By using single quotes, you can ensure that the string is interpreted exactly as it is written without any unexpected errors.

$name = 'John';
echo 'Hello, ' . $name . '!'; // Output: Hello, John!
