因此,我希望通过if语句将数字添加到字符串中。 例如:
a = 2;
b = 1;
if($a == 2) {
$total + 1;
}
if($b == 1) {
$total + 1;
}
echo $total;
显然,这些不是我的if语句,但是如果它们起作用,那么我希望$ total等于2?这似乎很简单,但我无法解决?

是,这很简单。
$a = 2; // use $ to initialize
$b = 1;
$total =0; // define a total var to take changes
if($a == 2) {
$total += 1;// asign changes to total with = sign
}
if($b == 1) {
$total += 1;// asign changes to total with = sign
}
echo $total;// will give you 2
