Seems you haven t installed the Curl on your server  Check the PHP version of your server and run the following command to install the curl   sudo apt-get install php7 2-curl   Then restart the apache service by using the following command   sudo service apache2 restart   Replace 7 2 with your PHP version

This answer is for https request   Curl doesn t have built-in root certificates  like most modern browser do    You need to explicitly point it to a cacert pem file      curl setopt  ch  CURLOPT CAINFO    path to cert file cacert pem      Without this  curl cannot verify the certificate sent back via ssl   This same root certificate file can be used every time you use SSL in curl   You can get the cacert pem file here  http   curl haxx se docs caextract html  Reference PHP cURL Not Working with HTTPS

For Ubuntu  add extension php curl so to php ini to enable  if necessary  Then sudo service apache2 restart  this is generally taken care of automatically  but there are situations - eg  in shared development environments - where it can become necessary to re-enable manually    The thumbprint will match all three of these conditions    Fatal Error on curl init   call in php info  you will see the curl module author  indicating curl is installed and available   also in php info  you will see no curl config block  indicating curl wasn t loaded

RusAlex answer is right in that for Apache you have to install and enable curl and restart your apache service   sudo apt-get install php5-curl sudo service apache2 restart   On my Ubuntu Server with nginx and php5-fpm I however ran into the following problem  I had to restart nginx and php5-fpm like so   sudo service nginx restart sudo service php5-fpm restart   But I had non-working php5-fpm processes hanging around  which apparently is a bug in ubuntu https   bugs launchpad net ubuntu  source php5  bug 1242376 So I had to kill all idle php5-fpm processes to able to restart php5-fpm so that the curl module is actually loaded  sudo kill  lt Process Id of php5-fpm Process

For PHP 7 and Windows x64  libeay32 dll  libssh2 dll and ssleay32 dll should not be in apache bin and should only exist in php directory and add php directory in system environment variable  This work for me   Obvisouly in php ini you should have enable php curl dll as well

Just adding my answer for the case where there are multiple versions of PHP installed in your system  and you are sure that you have already installed the php-curl package  and yet Apache is still giving you the same error   curl init   undefined even if php-curl is enabled in Php 7

User · Answer

On newer versions of PHP on Windows  like PHP 7 x  the corresponding configuration lines suggested on previous answers here  have changed  You need to uncomment  remove the   at the beginning of the line  the following line  extension dir    quot ext quot  extension curl

Yet another answer     If you land here in Oct 2020 because PHP on the command line  CLI  has stopped working  guess what     some upgrades will move you to a different newer version of PHP silently  without asking  Run  php --version and you might be surprised to see what version the CLI is running  Then run  ll  usr bin php and you might be surprised to see where this is linking to  It s best to reference the SPECIFIC version of PHP you want when calling the PHP binary directly and not a symbolic link  Example   usr bin php7 3 will give you the exact version you want  You can t trust  usr bin php or even just typing php because an upgrade might switch versions on you silently

Trying to get Curl working via PHP and Apache on Windows      I kept getting an error saying  Call to undefined function  curl init     I made sure I had enabled curl with this line in my php ini file  extension php curl dll  I made sure the extension dir variable was being set properly  like this  extension dir    ext   I was doing everything everyone else said on the forums and curl was not showing up in my call to phpinfo    and I kept getting that same error from above   Finally I found out that Apache by default looks for php ini in the C  Windows folder  I had been changing php ini in my PHP installation folder  Once I copied my php ini into C  Windows  everything worked   Took me forever to figure that out  so thought I d post in case it helps someone else

You need to install CURL support for php   In Ubuntu you can install it via  sudo apt-get install php5-curl   If you re using apt-get then you won t need to edit any PHP configuration  but you will need to restart your Apache   sudo  etc init d apache2 restart   If you re still getting issues  then try and use phpinfo   to make sure that CURL is listed as installed   If it isn t  then you may need to open another question  asking why your packages aren t installing    There is an installation manual in the PHP CURL documentation

Had this problem but found the answer here   https   askubuntu com questions 1116448 cannot-enable-php-curl-on-ubuntu-18-04-php-7-2  Had to   sudo a2dismod php7 0   And   sudo a2enmod php7 2   Then   sudo service apache2 restart   This was after a system upgrade to next version of Ubuntu   All the other answers I found were stale  due to a bad cert apparently on the PPA most of them pointed out  but would probably not have worked anyway   The real issue was disabling the old versions of php  apparently   Found the solution here   https   askubuntu com questions 1116448 cannot-enable-php-curl-on-ubuntu-18-04-php-7-2
