What are the key differences between the original and edited PHP scripts provided, and how do these changes impact the functionality of the code?

The key difference between the original and edited PHP scripts is the inclusion of the correct syntax for concatenating strings in PHP. In the original script, the concatenation operator "." was missing between the strings and variables, causing syntax errors. By adding the concatenation operator, the edited script now correctly combines strings and variables to output the desired result. 

// Original PHP script
$name = "John";
$age = 30;
echo "My name is " $name " and I am " $age " years old.";

// Edited PHP script
$name = "John";
$age = 30;
echo "My name is " . $name . " and I am " . $age . " years old.";
