在while循环中更改变量

而不是像以下代码：

if ( $Boss1 ==1)
            {
                $Boss1_holder = $tick;
            }

            else if ( $Boss1 ==0)
            {
                $Boss1_holder = $cross;
            }



            if ( $Boss2 ==1)
            {
                $Boss2_holder = $tick;
            }
            else if ( $Boss2 ==0)
            {
                $Boss2_holder = $cross;
            }


            if ( $Boss3 ==1)
            {
                $Boss3_holder = $tick;
            }
            else if ( $Boss3 ==0)
            {
                $Boss3_holder = $cross;
            }


            if ( $Boss4 ==1)
            {
                $Boss4_holder = $tick;
            }
            else if ( $Boss4 ==0)
            {
                $Boss4_holder = $cross;
            }

我可以改为做这样的事情：

                $i = 1;
            while ($i <= 4) 
            {
                if ( $Boss[$i] ==1)
                {
                    $boss_holder[$i] = $tick;
                }

                else if ( $Boss[$i] ==0)
                {
                    $boss_holder[$i] = $cross;
                }

            }

我不完全确定如何做到这一点。目前如果只有4组if else语句，但我的程序后来需要大约30个，我宁愿像我的第二个块那样会减少所需的行数。我是在正确的轨道上。我认为$ boss_holder [$ i]部分不正确，因为[i]会成为数组的一部分？但是我不知道如何正确地写这个。我查看了php手册页，但很多例子都是复杂的，超出了我需要的范围。

澄清我是否已经解释得很糟糕。我试图在变量$ boss_holder的末尾添加一个值，该值随着while循环计数器

递增

有几种方法可以做到...... 

$boss = new array(1, 2, 3, 4);
foreach($boss as $value){
    switch($value){
         case 1: 
            //do something
         break;
         case 2: 
            //something else;
         break;
    }
}

可能就是我写它的方式。

编辑：如果您正在寻找干净的代码，您可以这样做：

<强> bosshandler.php： 

function doSomethingWithBoss($value){
    switch($value){
         case 1: 
            return "boss equals 1";
         break;
         case 2: 
            return "boss equals 2";
         break;
    }
}

您的脚本页面： 

include bosshandler.php;
$boss = new array(1, 2, 3, 4);
foreach($boss as $value){
    echo doSomethingWithBoss($value);
}

好的，再试一次。我想我现在看到你在问什么：

您想要分配一个变量，以便您的数组匹配。如果您在$boss[1]，您希望为$boss_holder['1']分配内容，那是正确的吗？如果是这样，你不想使用foreach数组，因为它对于数组及其解析顺序有些不可预测。

相反，让我们使用for()循环，如下所示：

$boss = new Array(1, 2, 3, 4);
$boss_holder = new Array(); //empty
$length = count($boss);
//iterate through boss
for($i = 1; $i < $length; $i++){
    if($boss[$i] == 1){
        $boss_holder[$i] = $tick;
    }elseif($boss[$i] == 2){
        $boss_holder[$i] = $cross;
    }
}

再次修改以反映您的完整代码：

使用数组。重构您的代码，以便它使用数组。如果由于某种原因你完全不能或不会使用数组，你可以使用PHP的variable variables来完成你正在寻找的东西。它看起来像这样：

var $boss1_holder, $boss2_holder, $boss3_holder;
for($i=1; $i> 4; $i++){
    $variableName = 'boss' . $i . '_holder';
    $$variableName = 1;
}
echo $boss2_holder; //returns 2

答案 1 :(得分：1)

看看这段代码：

$bosses = new array(1, 2, 1, 1, 2);
$boss_holders = new array()

for ($i = 1; $i <= count($boss); $i++) {
    // if bosses[i] equals 1, we make the current boss_holder equal a $tick
    if($bosses[i] == 1) 
        array_push($boss_holders, $tick);

    // if the current boss doesn't equal 1 then it must equal 2
    // so we add a $cross instead
    else
        array_push($boss_holders, $cross);
}

请注意：上面的代码未经测试，可能包含错误，因为我的PHP有点（好吧，很多）生锈。

它的作用是创建一个新的老板数组（你可以将这个值设置为你老板的任何数字），以及一个名为$ boss_holders的空数组。然后我们通过一系列的老板，如果当前的Boss等于1，那么我们加上$ tick。否则，当前的Boss等于2，所以我们将添加$ cross。

当for循环运行完毕后，你将拥有一个反映老板价值的boss_holders数组。如果boss1 = 1，boss2 = 2，boss3 = 1，则数组boss_holders将如下所示：[$tick, $cross, $tick]，依此类推。例如，当您需要访问boss_holder_2的值时，您可以通过访问boss_holder数组来获得该值：boss_holders[2]。

这有意义吗？这就是你需要的吗？

答案 2 :(得分：0)

也许你可以使用switch。

从第一个例子开始：

if ($i == 0) {
  echo "i equals 0";
} elseif ($i == 1) {
  echo "i equals 1";
} elseif ($i == 2) {
  echo "i equals 2";
}

是一样的：

switch ($i) {
  case 0:
    echo "i equals 0";
    break;
  case 1:
    echo "i equals 1";
    break;
  case 2:
    echo "i equals 2";
    break;
}

但看起来更干净。

答案 3 :(得分：0)

Have you tried using variable variables? The first script will print out the variables created, while the second demonstrates that a variable can be defined or determined by modifying the "if" statement.  Maybe this will be helpful for your situation. `

`“;     $ I ++;     }     ？＆GT; 

<?php
$i=1;
$boss4_holder=true;

while($i<10){
    $q="boss".$i."_holder";

    if ($$q==true){
         echo "true";
    }
$i++;
}
?>
