How do I print all the values stored in a variable.

You are using string concatenation to create $tog (PHP: String Operators - Manual[^]). So that is a string variable containing only a single value.

You might create a concatenated string by inserting a separation character:

$tog = $name1 . '.' . $name2;

Then it can be later splitted into the original strings provided that those did not contain the separation character.

You might use a string array instead (PHP: Arrays - Manual[^]):

$tog = array($name1, $name2);

To print all values from such an array:

$count = count($array);
for ($i = 0; $i < $count; $i++) {
    if ($count > 0) {
        echo ".";
    }
    echo $array[$i];
}
echo "\n";
