How to concat string in PHP

Question

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 +)

Here's an overview: [Reference - What does this symbol mean in PHP?](http://stackoverflow.com/questions/3737139/reference-what-does-this-symbol-mean-in-php) — mario, Mar 17 '11 at 19:19
`while (1=1){` is the cause of the problem, isn't it? You can't assign a value to `1`, IIRC — Eric, Mar 17 '11 at 19:27

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

$string .= 'lol';

+ is for addition.

$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.
