Shared Hosting
If you are on shared hosting and do not have command line access to your web server or access to php.ini, you may have to contact your web host to see if they support the cURL PHP extension. Many web hosts disable this extension by default for security reasons but may enable it manually for you on request.
Install cURL extension for Apache/Nginx on Linux
If you have shell access to your Apache or Nginx web server, make sure the cURL extension is installed:
sudo apt-get install php-curlYou must also restart your web server for changes to take effect.
To restart Apache, run:
sudo service apache2 restartTo restart Nginx, run:
sudo service nginx restartNow test cURL with:
curl google.comIf you see some HTML, cURL is working correctly.
Check php.ini
If cURL is installed but you are still getting “Call to undefined function curl_init()”, you may need to enable the extension in your php.ini file.
Firstly, locate your php.ini file: Where is my PHP php.ini Configuration File Located?
In the example below, we are editing the php.ini file for Apache with PHP 7.2.
sudo nano /etc/php/7.2/apache2/php.iniPress CTRL + W and search for curl.
Remove the ; semicolon from the beginning of the following line. This line may look different depending on your version of PHP, just remove the semicolon.
;extension=curl
To save file and exit, press CTRL + X, press Y and then press ENTER.
You must restart your web server for changes to take effect.
To restart Apache, run:
sudo service apache2 restartTo restart Nginx, run:
sudo service nginx restartNow test cURL with:
curl google.comIf you see some HTML, cURL is working correctly.
Windows
If you’re on Windows, go to your php.ini file and search for “curl”.
Remove the ; semicolon from the beginning of the following line.
;extension=curl
If you are on an older version of PHP, the line might look like below.
;extension=php_curl.dll
After you have saved the file you must restart your HTTP server software before this can take effect.
Let me know if this helped. Follow me on Twitter, Facebook and YouTube, or 🍊 buy me a smoothie.
thanks. it work.
btw. did you know how to make array zero.
I mean like this
$variable = [];
but when I run it. it get error.
this works for me.:
sudo apt-get install php-curl
all other sites says to run commands, change php.ini, that did not work for me.
Thanks you for posting this.
I also have the same issue.
Checked using phpinfo() and cURL is listed.
Using php -m, curl is listed.
Checked php.ini both on php and apache and it is enabled.
Checked on wamp > php > extensions it is also checked but still Call to undefined function curl_init().
After upgrading to PHP 7.3.8 and with extension=php_curl.dl correctly enabled in my php.ini, I still receive the error: “Fatal error: Uncaught Error: Call to undefined function curl_init()”. Strange.
Run
php -m. Is curl listed? if not, make sure you are editing the correct php.ini file. Trylocate php.inito find it. Also make sure to restart your web server after editing php.ini.
