Fatal error: Call to undefined function curl_init()

Question

<?php $filename = "xx.gif"; $handle = fopen($filename, "r"); $data = fread($handle, filesize($filename));  // $data is file data $pvars   = array('image' => base64_encode($data), 'key' => IMGUR_API_KEY); $timeout = 30; $curl    = curl_init();  curl_setopt($curl, CURLOPT_URL, 'http://api.imgur.com/2/upload.xml'); curl_setopt($curl, CURLOPT_TIMEOUT, $timeout); curl_setopt($curl, CURLOPT_POST, 1); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl, CURLOPT_POSTFIELDS, $pvars);  $xml = curl_exec($curl);  curl_close ($curl);  var_dump($xml); ?> 

I'm playing with the Imgur API, but it doesn't seems to work. PHP.net says that curl_init() is in PHP5, but my host says it isn't. How can I make this work?

Answer 1

On old versions of Debian and Ubuntu, you solved this by installing the Curl extension for PHP, and restarting the webserver. Assuming the webserver is Apache 2:

sudo apt-get install php5-curl sudo service apache2 restart 

On newer versions, the package name as changed:

sudo apt install php-curl 

It's possible you'll need to install more:

sudo apt-get install curl libcurl3 libcurl3-dev; 

Answer 2

curl is an extension that needs to be installed, it's got nothing to do with the PHP version.
