How do I install the ext-curl extension with PHP 7?

Question

Well I was able to install it by :

sudo apt-get install php-curl

on my system. This will install a dependency package, which depends on the default php version.

After that restart apache

sudo service apache2 restart

sudo apt-get install php7.0-curl

If "sudo apt-get install php-curl" command doesnt work and display error We should run this code before install curl.

• step1 - sudo add-apt-repository ppa:ondrej/php
• step2 - sudo apt-get update
• step3 - sudo apt-get install php-curl
• step4 - sudo service apache2 restart

I tried the above solutions but it didn't work for me, just incase there any other person in the same shoes, this is what I did. I updated apt-get with the following command

sudo add-apt-repository ppa:ondrej/php

this i installed with php curl for the version of php that i was using, mine was

sudo apt-get install php7.1-curl

We can install any PHP7 Extensions which we are needed at the time of install Magento just use related command which you get error at the time of installin Magento

sudo apt-get install php7.0-curl
sudo apt-get install php7.0-dom
sudo apt-get install php7.0-mcrypt
sudo apt-get install php7.0-simplexml
sudo apt-get install php7.0-spl
sudo apt-get install php7.0-xsl
sudo apt-get install php7.0-intl
sudo apt-get install php7.0-mbstring
sudo apt-get install php7.0-ctype
sudo apt-get install php7.0-hash
sudo apt-get install php7.0-openssl
sudo apt-get install php7.0-zip
sudo apt-get install php7.0-xmlwriter
sudo apt-get install php7.0-gd
sudo apt-get install php7.0-iconv

If You have 404 or errors while sudo apt-get install php-curl just try

sudo apt-get update

and again try

sudo apt-get install php-curl

But notice what version was installed (i use php7.3 and php7.4-curl was installed - so it will not work)

try then

sudo apt-get install php7.3-curl

At the end You may want to restart services like: apache2 or php-fpm:

sudo apache2 restart
sudo service php7.3-fpm restart

this worked for me.

Check if curl is on the installed modules list for current php:

php -m
