How can I enable cURL for an installed Ubuntu LAMP stack?

Question

From Install Curl Extension for PHP in Ubuntu:

sudo apt-get install php5-curl

After installing libcurl, you should restart the web server with one of the following commands,

sudo /etc/init.d/apache2 restart

or

sudo service apache2 restart

You only have to install the php5-curl library. You can do this by running

sudo apt-get install php5-curl

Try:

sudo apt-get install php-curl

It worked on a fresh Ubuntu 16.04 (Xenial Xerus) LTS, with lamp-server and php7. I tried with php7-curl - it didn't work and also didn't work with php5-curl.

For those who are trying to install php-curl on PHP 7, it will result in an error. Actually if you are installing php-curl in PHP 7, the package name should be;

sudo apt-get install php-curl

Not php5-curl or php7-curl, just php-curl.

First thing to do: Check for the PHP version your machine is running.

Command Line: php -version

This will show something like this (in my case):

PHP 7.0.8-0ubuntu0.16.04.3 (cli) ( NTS ) Copyright (c) 1997-2016 The PHP Group

If you are using PHP 5.x.x => run command: sudo apt-get install php5-curl

If PHP 7.x.x => run command (in my case): sudo apt-get install php7.0-curl

Enable this extension by running:

sudo gedit /etc/php/7.0/cli/php.ini

And in the file "php.ini" search for keyword "curl" to find this line below and change it from

;extension=php_curl.dll

To:

extension=php_curl.dll

Next, save your file "php.ini".

Finally, in your command line, restart your server by running: sudo service apache2 restart.

I tried most of the previous answers, but it didn’t work for my machine, Ubuntu 18.04 (Bionic Beaver), but what worked for me was this.

First: check your PHP version

$ php -version

Second: add your PHP version to the command. Mine was:

  $ sudo apt-get install php7.2-curl

Lastly, restart the Apache server:

sudo service apache2 restart

Although most persons claimed that it not necessary to restart Apache :)

Fire the below command. It gives a list of modules.

 sudo apt-cache search php5-

Then fire the below command with the module name to be installed:

 sudo apt-get install name of the module
