How to combine two strings together in PHP? (17 answers)

Closed 2 years ago.

I want to do like this:

$string = "";
$string += "lol"; //maybe =+  > tried but both not working

But it isn't working, anyone suggestions? Google isn't making my life easy (cant search characters like = or +)

Answer 1

In PHP, string concatenation is done with the . operator:

$string .= 'lol';

+ is for addition.

Answer 2

$str = "";
while(...){
$str .= "lol.";
}

Input or place the ellipses with your loop condition, += is an add and increment operator.
