如何在php中的关联数组中找到最高值
如何在php中的关联数组中找到最高值
提问于 2022-09-21 15:59:35
$characters = [
"Character1" => ["Strength" => 1, "Dexterity" => 2,
"Intelligence" => 6, "Wisdom" => 6, "Charisma" => 3],
"Character2" => ["Strength" => 5, "Dexterity" => 4,
"Intelligence" => 1, "Wisdom" => 1, "Charisma" => 6],
"Character3" => ["Strength" => 6, "Dexterity" => 5,
"Intelligence" => 5, "Wisdom" => 1, "Charisma" => 5]
"Character4" => ["Strength" => 1, "Dexterity" => 2,
"Intelligence" => 4, "Wisdom" => 3, "Charisma" => 3]
];所以我的问题是，我怎样才能获得每个角色的最高品质。就像Character1一样，它要么是智慧，要么是智慧。我想重复这个角色的名字，最好的质量和与质量相关的价值。
foreach($attributs as $s_key => $value)
{
if($value > $max)
$max = max($attributs);
$maxkey = $s_key;
}
echo "<li>$max , $maxkey</li>";
echo "</ul>";我也有这段代码，但它只给出了每个字符的最高数字，而没有给出与数字相关的质量的名称。
foreach($characters as $names => $quality){
echo "$names";
echo max($quality);
}我知道他们根本没有工作，但这是我所能接近我想要的。

您可以使用max函数找到数组的最高值，同时也可以使用array_search()找到键。如果你有两个具有相同价值的技能，假设“智能”为6，而“智慧”为6，则这将失败，只会显示“智能”。你必须同时给他们看还是只给他们看一张？
$characters = [
"Character1" => ["Strength" => 1, "Dexterity" => 2, "Intelligence" => 6, "Wisdom" => 6, "Charisma" => 3],
"Character2" => ["Strength" => 5, "Dexterity" => 4, "Intelligence" => 1, "Wisdom" => 1, "Charisma" => 6],
"Character3" => ["Strength" => 6, "Dexterity" => 5, "Intelligence" => 5, "Wisdom" => 1, "Charisma" => 5],
"Character4" => ["Strength" => 1, "Dexterity" => 2, "Intelligence" => 4, "Wisdom" => 3, "Charisma" => 3]
];
foreach ($characters as $key => $character){
$value = max($character);
$skill = array_search($value, $character);
$characters[$key]['highest_skill'] = ['skill' => $skill, 'value' => $value];
}
print_r($characters["Character1"]);
// this will be shown

对每个字符使用max和array_search的组合以得到最高的
或者，使用temp对象我们将“保存”最高的键和值。演示中显示了这个额外的循环，但如果您在echo之后移动array_search，则可以删除该循环。
<?php
$characters = [
"Character1" => ["Strength" => 1, "Dexterity" => 2, "Intelligence" => 6, "Wisdom" => 6, "Charisma" => 3],
"Character2" => ["Strength" => 5, "Dexterity" => 4, "Intelligence" => 1, "Wisdom" => 1, "Charisma" => 6],
"Character3" => ["Strength" => 6, "Dexterity" => 5, "Intelligence" => 5, "Wisdom" => 1, "Charisma" => 5],
"Character4" => ["Strength" => 1, "Dexterity" => 2, "Intelligence" => 4, "Wisdom" => 3, "Charisma" => 3]
];
$res = new \stdClass();
foreach ($characters as $name => $char) {
$highest = array_search(max($char), $char);
$res->{$name} = [ $highest, $char[$highest] ];
}
foreach ($res as $name => $val) {
echo "Highest for {$name} is {$val[0]}! Value: {$val[1]}" . PHP_EOL;
}输出：
Highest for Character1 is Intelligence! Value: 6
Highest for Character2 is Charisma! Value: 6
Highest for Character3 is Strength! Value: 6
Highest for Character4 is Intelligence! Value: 4注意事项：如果有相同(最高)值的多个键，将使用第一个键！

虽然Ostone0的方法是正确的，但我认为它不需要这么复杂。只要尝试下面的方法就能得到你想要的。这更容易，也更直接。
foreach ($characters as $character => $names) {
$quality = array_search(max($names), $names);
$max = max($names);
echo 'The highest value for '. $character . ' is ' . $max . ' for the quality ' . $quality. PHP_EOL ;
}--这将输出以下
The highest value for Character1 is 6 for the quality Intelligence
The highest value for Character2 is 6 for the quality Charisma
The highest value for Character3 is 6 for the quality Strength
The highest value for Character4 is 4 for the quality Intelligence页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
