Firstly let us understand the concepts of curl, libcurl and PHP/cURL.

curl: A command line tool for getting or sending files using URL syntax.
libcurl: a library created by Daniel Stenberg, that allows you to connect and communicate to many different types of servers with many different types of protocols. libcurl currently supports the http, https, ftp, gopher, telnet, dict, file, and ldap protocols. libcurl also supports HTTPS certificates, HTTP POST, HTTP PUT, FTP uploading (this can also be done with PHP's ftp extension), HTTP form based upload, proxies, cookies, and user+password authentication.
PHP/cURL: The module for PHP that makes it possible for PHP programs to use libcurl.

Now you have an idea of the different terms.
For "PHP/cURL", most of developers also refer it to "curl in PHP", "curl with PHP" and so on. In this tutorial, we will call it "curl in PHP" to follow the common term.
The goal of the task in this tutorial is to use curl in PHP to fetch data from Google, and the searching term which will be sent to Google is "curl".
Let us start the task!

2. the goal

To use curl in PHP is very straightforward. The basic idea of using curl in PHP is

Initialize a curl session
Set various options for the session
Execute and fetch/send data from/to server
Close the session

To complete our goal, the code is simple as




step1: Initialize a curl session use curl_init().
step2: Set option for CURLOPT_URL. This value is the URL which we are sending the request to. Append a search term "curl" using parameter "q=". Set option for CURLOPT_RETURNTRANSFER, true will tell curl to return the string instead of print it out. Set option for CURLOPT_HEADER, false will tell curl to ignore the header in the return value.
step3: Execute the curl session using curl_exec().
step4: Close the curl session we have created.
step5: Output the return string.

Clearly there are more tasks you can do with curl in PHP, this tutorial is almost the simplest way to use it. However you can expand it to perform more tasks such as authentication to a password protected account and fetch data from there.
Areas you may need to look further to perform more advanced tasks are listed below:

curl_error(): For a more advanced system, you should always use curl_error() to check the errors based on the return value(bool) of the curl_exec().
curl_setopt() : There is a large number of options. Take a look at the manual file. This page has a clear explaination of various options.

is by EllisLab and now it is taken by British Columbia Institute of Technology. It is the simplest and light-weight PHP framework which lets you create robust web applications in no time. It is greatly appreciated for its speedy performance and smaller learning curve and suitable for highly scalable applications. And even though php codeigniter framework loosely follows Model-View-Controller pattern it doesn’t force it on you. While controller classes are required for application development, the models and view files are purely optional.
For starters, MVC stands for Model, View, Controller. It is a programing pattern used in developing
web apps. This pattern isolates the user interface and backend (i.e. database interaction from each other. A successful
implementation of this lets developers modify their user interface or backend with out affecting
the other. MVC also increases the flexibly of an app by being able to resuse models or views over
again). Below is a description of MVC.
• : The model deals with the raw data and database interaction and will contain functions
like adding records to a database or selecting specific database records. In CI the model
component is not required and can be included in the controller.
• : The view deals with displaying the data and interface controls to the user with.
In CI the view could be a web page, rss feed, ajax data or any other "page".
• : The controller acts as the in between of view and model and, as the name suggests,
it controls what is sent to the view from the model. In CI, the controller is also the place to load libraries and helpers.
An example of a MVC approach would be for a contact form.
1. The user interacts with the view by filling in a form and submitting it.
2. The controller receives the POST data from the form, the controller sends this data to the model
which updates in the database.
3. The model then sends the result of the database to the controller.
4. This result is updated in the view and displayed to the user.
