php - 将字符串数组发送到 php

Question

我想通过 Json 将字符串数组发送到 php 并在那里检索。

String[] Books = {"book1", "book2", "book3", "book4",..};

在 Json 中:

List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>;
nameValuePairs.add(new BasicNameValuePair("books", Books));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
...

在 php 端:

$books = $_POST['books'];
$result = json_decode($books);    // is this OK?

或者我可以像下面那样使用它吗？

$book1 = $result[0];

Answer 1

$jsonString = '["xxx@gmail.com","yy@gmail.com","rr@gmail.com"]';
$arrayOfYourEmails=json_decode($jsonString);

或者

$jsonString = "[\"xxx@gmail.com\",\"yy@gmail.com\",\"rr@gmail.com\"]";
$arrayOfYourEmails=json_decode($jsonString);

是的，你的代码是正确的

$books = $_POST['books'];
$result = json_decode($books);
