Installing ext-curl is a common task for developers working in PHP, particularly when they need to make HTTP requests within their applications. The extension offers a suite of functionalities for transferring data using various protocols. It’s a critical tool for interacting with RESTful APIs, logging into websites, sending mail via SMTP among others. Whether you are developing a content aggregator application, a data mining tool, or a simple application that interacts with third-party APIs, ext-curl could become one of your best allies.
Installing ext-curl starts with updating the system packages. It’s always recommended to start with the most recent versions of the software to avoid compatibility issues. After the update, the PHP-CURL installation occurs through a simple command. Below is the gist:
sudo apt-get update; //Update system packages sudo apt-get install php-curl; //Install PHP-CURL
After installation, a restart of the server (Apache or Nginx based on your setup) is crucial to make the extension available.
Step-By-Step Explanation of the Code
The first command, sudo apt-get update, is instructing the system to fetch the newest versions of all packages installed on the system. ‘sudo’ is a prefix that gives the command administrative privileges, ‘apt-get’ is the package handling utility in Ubuntu, and ‘update’ is the command to refresh the list of available packages.
sudo apt-get update
The second command, sudo apt-get install php-curl, is instructing the system to install the PHP-CURL package. ‘install’ is the command used to install a new package.
sudo apt-get install php-curl
Once the installation is complete, you need to restart your server for the changes to take effect.
