Question

有没有办法在下面的代码后发布包含多个值的字符串？请考虑第三个postfield $ multiple输出多个值提前致谢

<?php

$ch = curl_init(); //http post to another server

curl_setopt($ch, CURLOPT_URL,"http://www.example.com");

curl_setopt($ch, CURLOPT_POST, 1);

curl_setopt($ch, CURLOPT_POSTFIELDS,"username=$username&password=$password&multiple=$ "); 

// receive server response

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$server_output = curl_exec ($ch);

print_r($server_output);

curl_close ($ch);

Answer 1

我们可以在上面的代码中包含您的答案吗？

<?php

$ch = curl_init(); //http post to another server

curl_setopt($ch, CURLOPT_URL,"http://www.example.com");

curl_setopt($ch, CURLOPT_POST, 1);

  $username = 'user1';
  $password = 'strongpassword';

  $values = array(
    'username' => $username,
    'password' => $password,
    'multiple' => array(
        'value1',
        'value2',
        'value3',
    )
  );

$params = http_build_query($values);

curl_setopt($ch, CURLOPT_POSTFIELDS,$params); 

// receive server response

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$server_output = curl_exec ($ch);

print_r($server_output);

curl_close ($ch);

Answer 2

您可以使用http_build_query创建此查询字符串。

例如

<?php
  $username = 'user1';
  $password = 'strongpassword';

  $values = array(
    'username' => $username,
    'password' => $password,
    'multiple' => array(
        'value1',
        'value2',
        'value3',
    )
);

echo http_build_query($values);

输出：

username=user1&password=strongpassword&multiple%5B0%5D=value1&multiple%5B1%5D=value2&multiple%5B2%5D=value3

换句话说，多个参数应为multiple[]=value1&multiple[]=value2&multiple[]=value3

Answer 3

要发送多个值，您必须用逗号分隔它们：

[...]&multiple=a,b,c
