Why a full stop, “.” and not a plus symbol, “+”, for string concatenation in PHP?

Question

Why did the designers of PHP decide to use a full stop / period / \".\" as the string concatenation operator rather than the more usual plus symbol \"+\" ?

Is there

Answer 1

Logically + is used for numbers. While a dot is used to concatenate two sentences (strings) in a paragraph for example. Hence dot is used to concatenate strings. So it is pretty logical i believe. It is better that way...
