使用数组数据构建查询字符串 [英] Build query string with array data

问题描述

我向函数传递了一个包含一些答案的对象。然后，我执行以下操作来创建关联数组

I pass my function an object that contains some answers. I then do the following to create an associative array

$field_data = array();
foreach($submission->answers as $answer) {
    $field_data[$answer->question_id] = $answer->text + 1;
}

结果会像这样

array:15 [▼
  1 => 3
  2 => 4
  3 => 2
  4 => 5
]

我需要做的就是使用上述数据构建一个API调用。 API URL看起来像这样

What I need to do is build an API call using the above data. The API URL would look something like this

someAPI.com?api.php?function=calculatePrice&question 1 > = 3 & question2 = 4& question3 = 2& question4 = 5

someAPI.com?api.php?function=calculatePrice&question1=3&question2=4&question3=2&question4=5

问题编号在哪里是数组左侧的值，=符号后面的部分是数组右侧的值。

Where the question number is the value on the left side of the array, and the part after the = sign is the value on the right of the array.

什么是最好的方法？

谢谢

推荐答案

这可以通过 http-build-query 方法本身来实现的PHP。第二个参数接受前缀加在键之前。
密钥应为数字类型

This can be achieved with the http-build-query method itself of php. The second param accepts the prefix to prepend to the key. The key should be of numeric type

您可以使用 http-build-query 根据您的情况

You can use the http-build-query like this in your case

http_build_query($field_data, 'question');
