PHP string concatenation
提问by Illep
I need to know if its possible to concatenate strings, as follows ? and if not, what is the alternative of doing so ?
我需要知道是否可以连接字符串，如下所示？如果没有，这样做的替代方法是什么？
while ($personCount < 10) {
$result+= $personCount . "person ";
}
echo $result;
it should appear like 1 person 2 person 3person etc..
它应该看起来像1 person 2 person 3人等。
You cann't use the +sign in concatenation so what is the alternative ?
您不能+在连接中使用符号，那么替代方法是什么？
回答by abhshkdz
Just use .for concatenating.
And you missed out the $personCountincrement!
仅.用于连接。而你错过了$personCount增量！
while ($personCount < 10) {
$result .= $personCount . ' people';
$personCount++;
}
echo $result;

This should be faster.
这应该更快。
while ($personCount < 10) {
$result .= "{$personCount} people ";
$personCount++;
}
echo $result;

$personCount=1;
while ($personCount < 10) {
$result=0;
$result.= $personCount . "person ";
$personCount++;
echo $result;
}

I think this code should work fine
我认为这段代码应该可以正常工作
while ($personCount < 10) {
$result = $personCount . "people ';
$personCount++;
}
// do not understand why do you need the (+) with the result.
echo $result;
