Question

I need to get the json data from, http://vortaro.us.to/ajax/epo/eng/ + 'word'+ "/?callback=?" working example (not enough reputation)

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,

<?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 ;
*/
?>

Answer 1

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

That done, you can use json_decode() to parse the data into something useful.

• gumuruh: file_get_contents()? is that requiring an another php modules to be installed? :D
• David Cary: @gumuruh: file_get_contents() is built-in to PHP. :-)
• CodeBrauer: Using curl is a lot faster and will print better results. You can set timeouts caching and more. I will never use file_get_contents for api-request // Source -> Google: curl vs file_get_contents

Answer 2

Take a look at PHP Curl.

With this example you are able to the all the informations.

<?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.

Since PHP 5.2.0 the function json_decode is part of the core.

Answer 3

Old question, but still one of the top hits in Google, so here is my contribution on top of @DrDol's answer.

<?
 $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_RETURNTRANSFER which sends the response into the return value (and returns false on fail).
