如果值匹配，则从特定数组获取值[重复]

Question

如果电子邮件匹配，则从数组键 ['email'] 获取值。

如果用户的电子邮件与数组键值匹配，我想在 Wordpress 评论中打印“特殊用户”。

$match_email = '[email protected], [email protected]';


$config = [
    'special_user' => [
        'muskan' => [
            'age' => '24',
            'email' => '[email protected]'
        ],
        'khushi' => [
            'age' => '21',
            'email' => '[email protected]'
        ]
    ]
];



foreach ($config as $name => $users) {
    foreach ($users as $author => $email) {
        if (in_array($email['email'], $match_email)) {
            echo 'Special User';
            break;
        }
    }
}

Answer 1

它不起作用，因为您没有将数组传递给它：

in_array($user_data['email'], $match_email)

您需要将

$match_email

转换为带有

explode()

的数组。

<?php

$match_email = explode(', ', '[email protected], [email protected]');


$config = [
    'special_user' => [
        'muskan' => [
            'age' => '24',
            'email' => '[email protected]'
        ],
        'khushi' => [
            'age' => '21',
            'email' => '[email protected]'
        ]
    ]
];



foreach ($config as $name => $users) {
    foreach ($users as $author => $user_data) {
        if (in_array($user_data['email'], $match_email)) {
            echo 'Special User';
            break;
        }
    }
}

如果可能的话，您也可以首先使用数组：

<?php


$match_email = ['[email protected]', '[email protected]'];


$config = [
    'special_user' => [
        'muskan' => [
            'age' => '24',
            'email' => '[email protected]'
        ],
        'khushi' => [
            'age' => '21',
            'email' => '[email protected]'
        ]
    ]
];



foreach ($config as $name => $users) {
    foreach ($users as $author => $email) {
        if (in_array($email['email'], $match_email)) {
            echo 'Special User';
            break;
        }
    }
}
