What is the best way to determine the type of a variable in PHP?

To determine the type of a variable in PHP, you can use the `gettype()` function. This function accepts a variable as an argument and returns a string representing the data type of that variable. This can be useful when you need to perform different operations based on the type of a variable. 

$var = "Hello";
$type = gettype($var);
echo "The variable is of type: " . $type;
