How can the Reflection API in PHP be used to document variables in code?

When documenting variables in code, the Reflection API in PHP can be used to retrieve information about the variables, such as their data type, name, and value. This can be particularly useful for generating documentation or debugging purposes. 

// Example code snippet using Reflection API to document variables
$var1 = 123;
$var2 = "Hello";

$reflectionVar1 = new ReflectionVariable('var1');
$reflectionVar2 = new ReflectionVariable('var2');

echo "Variable 1: " . $reflectionVar1->getName() . " - Type: " . gettype($var1) . " - Value: " . $var1 . "\n";
echo "Variable 2: " . $reflectionVar2->getName() . " - Type: " . gettype($var2) . " - Value: " . $var2 . "\n";
