What are some common misconceptions or difficulties beginners face when trying to manipulate variables in PHP?

One common misconception beginners face when manipulating variables in PHP is not understanding the difference between single quotes and double quotes. Single quotes treat variables as literal strings, while double quotes allow for variable interpolation. To properly manipulate variables in PHP, it's important to use the correct quotation marks to ensure variables are parsed correctly. 

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