PHP字符串串联 [英] PHP string concatenation

问题描述

我需要知道是否可以连接字符串，如下所示?如果没有，那么还有什么选择呢?

I need to know if its possible to concatenate strings, as follows ? and if not, what is the alternative of doing so ?

while ($personCount < 10) {
$result+= $personCount . "person ";
}

echo $result;

它应该看起来像1 person 2 person 3人等.

您不能在连接中使用+符号，那么有什么替代方法?

You cann't use the + sign in concatenation so what is the alternative ?

推荐答案

只需使用.进行串联. 而且您错过了$personCount增量！

Just use . for concatenating. And you missed out the $personCount increment!

while ($personCount < 10) {
    $result .= $personCount . ' people';
    $personCount++;
}

echo $result;
