推荐员工算法php（php 推荐算法）

以下是一个简单的员工推荐算法的示例代码：

<?php

// 员工数据
$employees = [
    [
        'name' => 'John',
        'skills' => ['PHP', 'JavaScript', 'HTML'],
    ],
    [
        'name' => 'Jane',
        'skills' => ['PHP', 'CSS'],
    ],
    [
        'name' => 'Mike',
        'skills' => ['JavaScript', 'HTML', 'CSS'],
    ],
    [
        'name' => 'Sarah',
        'skills' => ['PHP', 'JavaScript'],
    ],
];

// 目标员工
$targetEmployee = [
    'name' => 'David',
    'skills' => ['PHP', 'JavaScript'],
];

// 计算员工之间的技能差异
function calculateSkillDifference($employee1, $employee2)
{
    $skills1 = $employee1['skills'];
    $skills2 = $employee2['skills'];

    $commonSkills = array_intersect($skills1, $skills2);

    return count($skills1) + count($skills2) - 2 * count($commonSkills);
}

// 找到最佳匹配员工
function findBestMatch($targetEmployee, $employees)
{
    $bestMatch = null;
    $lowestDifference = PHP_INT_MAX;

    foreach ($employees as $employee) {
        $difference = calculateSkillDifference($targetEmployee, $employee);

        if ($difference < $lowestDifference) {
            $bestMatch = $employee;
            $lowestDifference = $difference;
        }
    }

    return $bestMatch;
}

// 执行推荐算法
$bestMatch = findBestMatch($targetEmployee, $employees);

// 输出结果
echo "最佳匹配员工是：" . $bestMatch['name'] . "\n";
echo "技能差异：" . calculateSkillDifference($targetEmployee, $bestMatch) . "\n";

这个算法基于员工之间的技能差异来进行推荐。它计算目标员工与每个员工之间的技能差异，并选择差异最小的员工作为最佳匹配。
