Make HTTP Requests Using Curl and Decoding JSON Responses in PHP
PHP has Curl library that let’s you communicate with other servers. The Curl libaray is enabled by installing cUrl extension in PHP.INI. You just need to uncomment “extension=php_curl.dll” in PHP.INI file to install Curl library.
As a php developer, sometimes we need to get data from other server or need to make request to other server like payment gateways integration, fetching catalog etc. By using Curl library, You can make http request to a server and get the required data. you can also decode the JSON result with json_decode() function.
Here in this post, We will make a Curl request to soundcloud api to get the details of a track. The result will be a list of track details in json data format. The json_decode() function will then convert the json object into an array and will finally print out the details.
- <?php
- $requesturl=‘http://api.soundcloud.com/tracks/54518918.json?client_id=d70658d99cfe7bf44a398e3f8b1785ed’;
- $ch=curl_init($requesturl);
- curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
- $cexecute=curl_exec($ch);
- curl_close($ch);
- $result = json_decode($cexecute,true);
- echo “Id: “.$result['id'];
- echo “<br>Title: “.$result['title'];
- echo “<br>Description: “.$result['description'];
- ?>
Output:
Id: 54518918

Some of the PHP code will not work without the help of the php library. Your work on curl is very much appreciated and in good functions. I love this stuff although sometimes a bit confusing on some parts but over all this one works perfectly. Thanks.
