php中怎么接受数组

<form method=”post” action=”process.php”>

<input type=”checkbox” name=”fruits[]” value=”apple”> Apple<br>

<input type=”checkbox” name=”fruits[]” value=”banana”> Banana<br>

<input type=”checkbox” name=”fruits[]” value=”pear”> Pear<br>

<input type=”submit” value=”Submit”>

</form>

// 使用[], 取出checkbox选中的值

$selectedFruits = $_POST[fruits];

// 使用list, 将checkbox的值赋值到变量中

list($apple, $banana, $pear) = $_POST[fruits];

{

“name”: “John Smith”,

“age”: 30,

“email”: “john.smith@example.com”,

“address”: {

“street”: “123 Main St”,

“city”: “Anytown”,

“state”: “CA”,

“zipcode”: “12345”

},

“hobbies”: [

“reading”,

“swimming”,

“traveling”

]

}

$json = {“name”:”John Smith”,”age”:30,”email”:”john.smith@example.com”,”address”:{“street”:”123 Main St”,”city”:”Anytown”,”state”:”CA”,”zipcode”:”12345″},”hobbies”:[“reading”,”swimming”,”traveling”]};

$array = json_decode($json, true); // 第二个参数为true，将结果以数组返回

SELECT name, email, phone FROM users WHERE id = 1;

// 假设连接已经建立

$result = mysqli_query($conn, “SELECT name, email, phone FROM users WHERE id = 1;”);

if ($result) {

// 使用 mysqli_fetch_assoc() 得到关联数组

$row = mysqli_fetch_assoc($result);

echo Name: . $row[name] . <br />;

echo Email: . $row[email] . <br />;

echo Phone: . $row[phone] . <br />;

mysqli_free_result($result);

}

function printNames($names) {

foreach ($names as $name) {

echo $name . <br />;

}

}

// 调用函数并传递数组

$names = array(John, Mary, Tom);

printNames($names);
