What advice would you give to PHP beginners to prevent similar errors in their code?

Issue: Using single quotes in PHP will not parse variables inside them, leading to errors when trying to concatenate strings with variables. Solution: Use double quotes when concatenating strings with variables in PHP to ensure that the variables are parsed correctly. Code snippet: 

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