PHP array loop replaced with Chinese

In web development, PHP arrays are a commonly used data structure. Arrays provide a simple and efficient way to store and manipulate data. However, in some scenarios, the default output of an array may not be intuitive or beautiful enough, especially when the keys or values ​​in the array are English words or numbers. Therefore, we can use a loop to replace English in the array with Chinese to enhance the beauty and semantics.

The following is an example array:

$person = array(
    'name' => 'Tom',
    'age' => 25,
    'gender' => 'male',
    'country' => 'USA'
);

We can use a foreach loop to iterate through the array while checking whether each key or value needs to be replaced. For example, if we want to replace the key name with Chinese:

foreach($person as $key => $value) {
    switch($key) {
        case 'name':
            echo '姓名：'.$value.'<br>';
            break;
        case 'age':
            echo '年龄：'.$value.'<br>';
            break;
        case 'gender':
            echo '性别：'.$value.'<br>';
            break;
        case 'country':
            echo '国家：'.$value.'<br>';
            break;
        default:
            echo $key.': '.$value.'<br>';
    }
}

In each case, we use a different Chinese key name to replace the original key name. For any key name that is not listed, we output it as is. The output of this code is as follows:

姓名：Tom
年龄：25
性别：male
国家：USA

Similarly, we can use loops to replace values. In this example, we want to replace the English words "male" and "USA" with their corresponding Chinese counterparts:

$translation = array(
    'male' => '男',
    'female' => '女',
    'USA' => '美国',
    'China' => '中国'
);

foreach($person as $key => $value) {
    switch($key) {
        case 'gender':
            echo '性别：'.$translation[$value].'<br>';
            break;
        case 'country':
            echo '国家：'.$translation[$value].'<br>';
            break;
        default:
            echo $key.': '.$value.'<br>';
    }
}

In this example, we manually created a translation array for each value that needs to be replaced $ translation. We then use a foreach loop to iterate through this array and use it to replace the original value. Note that we only replace the values ​​of the gender and country keys, as these are the only two keys we want to replace.

The output of this code is as follows:

name: Tom
age: 25
性别：男
国家：美国

Finally, we can also combine the above two examples into a loop to replace keys and values ​​at the same time. The following is the corresponding code:

$translation = array(
    'name' => '姓名',
    'age' => '年龄',
    'gender' => '性别',
    'male' => '男',
    'female' => '女',
    'country' => '国家',
    'USA' => '美国',
    'China' => '中国'
);

foreach($person as $key => $value) {
    echo $translation[$key].': ';
    if(array_key_exists($value, $translation)) {
        echo $translation[$value].'<br>';
    } else {
        echo $value.'<br>';
    }
}

In this code, we put the translation of the key name and key value in the same array $translation. We then iterate over the original array $person and use $translation to replace both keys and values. In addition, we also use the array_key_exists function to check whether there is a corresponding value translation in $translation.

The output of this code is as follows:

姓名: Tom
年龄: 25
性别: 男
国家: 美国

In web development, arrays are a very common data type, so in a production environment it is very likely that you need to convert something in the array Some strings are replaced with Chinese characters. While the above solution may be slightly cumbersome, it is entirely doable and can be modified appropriately as needed.
