How can variables be concatenated in PHP without losing their original values?

When concatenating variables in PHP, you can use the dot (.) operator to combine them into a single string without losing their original values. This allows you to create a new string that includes the values of multiple variables. Make sure to include the dot operator between each variable to concatenate them properly. 

$var1 = "Hello";
$var2 = "World";
$concatenated = $var1 . " " . $var2;
echo $concatenated; // Output: Hello World
