<?php
// 将数组转换为字符串
$array = ['apple', 'banana', 'cherry'];
$string = implode(', ', $array);
echo $string; // 输出: apple, banana, cherry

// 将字符串转换为数组
$string = 'apple,banana,cherry';
$array = explode(', ', $string);
print_r($array); // 输出: Array ( [0] => apple [1] => banana [2] => cherry )

// 将数组转换为对象
$array = ['name' => 'John', 'age' => 30];
$object = json_decode(json_encode($array));
print_r($object); // 输出: stdClass Object ( [name] => John [age] => 30 )

// 将对象转换为数组
$object = (object) ['name' => 'John', 'age' => 30];
$array = get_object_vars($object);
print_r($array); // 输出: Array ( [name] => John [age] => 30 )
?>

$array = ['苹果', '香蕉', '樱桃'];
$string = implode(', ', array_map('mb_convert_encoding', $array, ['UTF-8', 'GBK']));

$array = json_decode(json_encode($object), true);
print_r($array); // 输出: Array ( [name] => John [age] => 30 )
