How to concat string in PHP
提问by user657601
I want to do like this:
我想这样做：
$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 +)
但它不起作用，有人建议吗？Google 并没有让我的生活变得轻松（无法搜索 = 或 + 等字符）

In PHP, string concatenation is done with the .operator:
在 PHP 中，字符串连接是通过.运算符完成的：
$string .= 'lol';
+is for addition.
+是为了加法。
回答by Marcel
$str = "";
while(...){
$str .= "lol.";
}
Input or place the ellipses with your loop condition, += is an add and increment operator.
输入或放置带有循环条件的省略号，+= 是加法和增量运算符。
