Concatenation is the process of appending one string with another, which can be achieved with the dot operator in PHP, like this: $text = "Hello "; $text2 = "world!"; $text .= $text2; echo $text; The output is hello world.

i am not sure for php but in most programming languages concatenation means to concate two string like : "string1" + "string2" so result string is: "string1string2"

Vukan, if you use the + operator with a string you will get unexpected behavior. PHP will convert the string to a number and try to add it. If not possible, it will return 0.

It's the dot (.) that makes the concatenation in PHP. It's part of the so called string operators. Examp#See below: $firstName = 'John'; $lastName = 'Doe'; $fullName = $firstName . ' ' . $lastName; echo $fullName; It outputs "John Doe", with space in between them.
