PHP while 循环问题

Question

我主要是一个 CSS 和 HTML 的人，但我最近开始涉足 PHP。

我不明白为什么这个脚本会挂起:

$loop_Until = 10;

while($i < $loop_Until)
{
    // do some code here
    $loop_Until = $loop_Until + 1;
}

有人可以帮忙吗？

Answer 1

固定代码

$loop_Until = 10;
$i = 0;

    while($i < $loop_Until)
    {
        // do some code here
        $i = $i + 1;
    }

代码说明:

// A variable called loop until is set to 10
$loop_Until = 10;  

// While the variable i is less than 10
// NOTE:  i is not set in code snippet, so we have no way of knowing what value it is, if it is greater than 10 it might be infinite
while($i < $loop_Until)
{
    // Increment the 10 value up 1 every time, i never changes!
    $loop_Until = $loop_Until + 1;
}
