关于员工上网监控系统中 PHP 关联数组算法的学术解析

<?php
// 创建一个简单的关联数组
$employeeData = array(
    "John" => "Sales",
    "Jane" => "Marketing",
    "Bob" => "Engineering"
);
// 访问关联数组中的元素
echo $employeeData["John"];
?>

<?php
// 假设已经获取到员工ID和网络访问记录
$employeeId = "E001";
$networkRecord = array(
    "timestamp" => time(),
    "url" => "https://example.com",
    "action" => "访问"
);
// 使用关联数组存储员工网络活动记录
$employeeNetworkRecords = array();
if (!isset($employeeNetworkRecords[$employeeId])) {
    $employeeNetworkRecords[$employeeId] = array();
}
array_push($employeeNetworkRecords[$employeeId], $networkRecord);
// 输出员工网络活动记录
print_r($employeeNetworkRecords[$employeeId]);
?>

<?php
// 定义网络访问规则
$networkRules = array(
    "https://www.vipshare.com" => "允许",
    "https://malicioussite.com" => "禁止",
    "https://socialmedia.com" => "禁止"
);
// 检查某个URL的访问规则
$urlToCheck = "https://www.vipshare.com";
if (isset($networkRules[$urlToCheck])) {
    echo "对 $urlToCheck 的访问权限为: ". $networkRules[$urlToCheck];
} else {
    echo "未定义对 $urlToCheck 的访问规则";
}
