感谢任何帮助。 如果我在职能之前打电话显示,我似乎无法得到一笔总价值。
页: 1
[main code here]
$sum = $valueObtainedAfterWhileLoop;
function showSum(){
global $sum;
return $sum;
}
echo getSum();
EXAMPLE2: (这并不奏效——不重犯,但无价值印在屏幕上)
echo getSum();
[main code here]
$sum = $valueObtainedAfterWhileLoop;
function showSum(){
global $sum;
return $sum;
}
我需要用上页顶上的一笔总价值。 我能做些什么?
绝对没有。 这些变量尚未分配到,因此没有用处。 而是在职能中计算。
