PHP通过使用数据键获取数组值 - PHP getting array values by using data keys

PHP getting array values by using data keys

本文关键字：获取数组数据 PHP | 更新日期: 2023-09-27

我得到了这个数组:

   $allImmunities = array(
    'poisonPercent' => '/images/gems/earth.gif',
    'earthPercent' => '/images/gems/earth.gif',
    'paralyzePercent' => '/images/gems/paralyze.gif',
    'deathPercent' => '/images/gems/death.gif',
    'energyPercent' => '/images/gems/energy.gif',
    'icePercent' => '/images/gems/ice.gif',
    'firePercent' => '/images/gems/fire.gif',
    'physicalPercent' => '/images/gems/physical.gif',
    'holyPercent' => '/images/gems/holly.gif',
    'invisiblePercent' => '/images/gems/invisible.gif'
   );

和$data变量，它们总是返回这样的东西:

$data = 'physicalPercent:10, icePercent:10, holyPercent:-10';

现在我需要爆炸(?)$data与:获得数组键值或有更好的方法?

我不希望它像这样工作:

$v = explode(':', $data);

如果$v[0]是fe。physicalPercent，它会选择

/images/gems/physical.gif

同时，我需要操作:后面的数值，所以我需要像这样工作:

if($v[1] > xx and $v[1] < yy)

选择与$v[0]匹配的数组值。

对不起，我的英语不好，我需要帮助:)。

如下所示:

foreach(explode(', ', $data) as $prop) {
   list($propName, $propVal) = explode(':', $prop);
   // $propName would be physicalPercent, 
   // $propVal would be 10 for the first iteration, etc
   // now get the image
   $img = $allImmunities[$propName];
   echo $img . '<br/>';
}

完整代码(包含您的数据):

<?php
   $allImmunities = array(
    'poisonPercent' => '/images/gems/earth.gif',
    'earthPercent' => '/images/gems/earth.gif',
    'paralyzePercent' => '/images/gems/paralyze.gif',
    'deathPercent' => '/images/gems/death.gif',
    'energyPercent' => '/images/gems/energy.gif',
    'icePercent' => '/images/gems/ice.gif',
    'firePercent' => '/images/gems/fire.gif',
    'physicalPercent' => '/images/gems/physical.gif',
    'holyPercent' => '/images/gems/holly.gif',
    'invisiblePercent' => '/images/gems/invisible.gif'
   );
$data = 'physicalPercent:10, icePercent:10, holyPercent:-10';
foreach(explode(', ', $data) as $prop) {
   list($propName, $propVal) = explode(':', $prop);
   // $propName would be physicalPercent,
   // $propVal would be 10 for the first iteration, etc
   // now get the image
   $img = $allImmunities[$propName];
   echo $img ."'n";
}

输出:

$ php game.php
/images/gems/physical.gif
/images/gems/ice.gif
/images/gems/holly.gif

您可以首先分解为键/值对，然后根据它们检索值:

$data = 'physicalPercent:10, icePercent:10, holyPercent:-10';
foreach(explode(', ', $data) as $item)
{
    list($key, $value) = sscanf($item, '%[a-zA-Z]:%d');
    echo $allImmunities[$key], "'n";
}

演示

输出():

/images/gems/physical.gif
/images/gems/ice.gif
/images/gems/holly.gif

使用for循环和爆炸数据来获取信息
