How do I concatenate strings in PHP?

To concatenate strings in PHP, you can use the concatenation operator (' . ') and the concatenate assignment operator (' .= '). The concatenation operator (' . ') returns the concatenation result of the right and left arguments. When concatenating, each subsequent line is added to the end of the previous one. A value of any type that is concatenated with a string will be implicitly converted to a string and then concatenated. The assignment operator (' .= ') adds the argument on the right side to the argument on the left side. This is a shorter way to concatenate the arguments and assign the result to the same variable. In this PHP String Concatenation example, we use the concatenation operator (' . ') and return the concatenating arguments.
