我需要从http://vortaro.us.to/ajax/epo/eng/+ 'word'+ "/?callback=?"获取 json 数据 工作示例（没有足够的声誉）
I know how to do it in javascript, But I need my php file to get this data, It needs to be server side, Thanks I'm new I have spent all day trying to figure this out. fopen and fread isn't working,
我知道如何在 javascript 中做到这一点，但我需要我的 php 文件来获取这些数据，它需要在服务器端，谢谢我是新手，我花了一整天的时间试图解决这个问题。fopen 和 fread 不起作用，
<?php
$vorto = $_GET['vorto']; // Get the Word from Outer Space and Search for it!
if (isset($vorto))
{
echo $vorto;
} else {
$Help = "No Vorto -> add ?vorto=TheWordYouWant to the end of this website";
echo $Help;
}
$url1 = "http://vortaro.us.to/ajax/epo/eng/";
$url2 = "/?callback=?";
$finalurl= $url1 . $vorto . $url2;
/*
PLEASE HELP
$v1 = fopen($finalurl ,"r");
echo $v1;
$frv1 = fread($v1,filesize($v1));
echo $frv1 ;
*/
?>

file_get_contents()can be used on a URL. A simple and convenient way to handle http page download.

Take a look at PHP Curl.
看看PHP Curl。
With this example you are able to the all the informations.
通过此示例，您可以了解所有信息。
<?php
// create a new cURL resource
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_HEADER, 0);
// grab URL and pass it to the browser
curl_exec($ch);
// close cURL resource, and free up system resources
curl_close($ch);
?>
Make sure that PHP Curl is enables in your php.ini. If you want to use fopen the setting allow_url_fopen must be 'ON' in your php.ini. Checkout phpinfo() for all the settings.
确保在您的 php.ini 中启用了 PHP Curl。如果您想使用 fopen，则 php.ini 中的设置 allow_url_fopen 必须为“ON”。检查 phpinfo() 以获取所有设置。
Since PHP 5.2.0 the function json_decodeis part of the core.
自 PHP 5.2.0 起，函数json_decode是核心的一部分。

Old question, but still one of the top hits in Google, so here is my contribution on top of @DrDol's answer.
老问题，但仍然是谷歌的热门话题之一，所以这是我在@DrDol 回答基础上的贡献。
<?
$url = "http://www.example.com/api/v1/endpoint";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = json_decode(curl_exec($ch));
curl_close($ch);
?>
Note the user of the CURLOPT_RETURNTRANSFERwhich sends the response into the return value (and returns false on fail).
请注意CURLOPT_RETURNTRANSFER将响应发送到返回值中的用户（并在失败时返回 false）。
