Php 而循环不会结束

我正在运行一个基于文本的游戏，试图让一个函数使用while循环来重复自己，但当条件满足时，它不会停止

不会在任何地方更改/减少

在循环结束前将其递减：

$ir['steps'] -= 1;

就在循环的结束括号之前。
请仅发布相关代码。请将代码显著减少到您面临的问题以及复制它所需的代码，以便在循环中更改$ir['steps']？在浏览了itmysql_查询之后，我看不到任何地方（“更新用户集crystals=crystals+$rewardtok，steps=steps-1，其中userid=$userid”）；这包括在每个结果中，我不会说这个问题因为包含HTML而被“JavaScript”或“HTML”标记，也不会因为它是一个函数而被称为“函数”。mysql_查询（“更新用户集crystals=crystals+$rewardtok，steps=steps-1，其中userid=$userid”）；是的，您正在数据库中更新它，但不是在php循环本身中。您应该在循环中执行与在数据库中相同的操作。如果您更改了数据库中的数据，PHP将不会自己意识到这些更改。你应该写代码这样做。哦，对不起，我是新来的。我该怎么做？如果答案有效，就接受吧，很高兴我能帮助你。
$ir['steps']

$ir['steps'] -= 1;
