$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 +)

Solution 1:[1]

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

$string .= 'lol';

+ is for addition.

Solution 2:[2]

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

Replace the ellipses with your loop condition, (+=) is an addition assignment operator that adds the value of the right operand to a variable and assigns the result to the variable.
