1 + 2 is 3 (integer)
Since we are adding int to int, the result will be an int since the grammar of the addition function specify so.
1 . 2 is 12 (string)
In this, we have used a dot (.) which is the way to concatenate two strings together so the result shall be a string.
1 + 2 is 3 (double)
Whenever a double/float is added to an integer or vise versa, php cast the result as a double or float to meet the best result.
1 . 2 is 12 (string)
As mentioned earlier, the dot is always used to concatenate two strings.

1.0 word + 2 is 3 (double)

1.0 word . 2 is 1.0 word2 (string)
As mentioned earlier, the dot is always used to concatenate two strings.
