    There are two <a href="language.types.string.php" class="type string">string</a> operators. The first is the

    concatenation operator (&#039;.&#039;), which returns the concatenation of its

    right and left arguments. The second is the concatenating assignment

    operator (&#039;<i>.=</i>&#039;), which appends the argument on the right side to

    the argument on the left side. Please read <a href="language.operators.assignment.php" class="link">Assignment

    Operators</a> for more information.
