How curl url in php?
Today, we’re going to explore the cURL extension in PHP, which allows you to make HTTP requests from your code. Show
Often you need to communicate with external websites in your day-to-day PHP development. Whether it’s calling third-party REST APIs to fetch data or downloading resources from an external website, you want a library which allows you to do it effortlessly. In PHP, there are different methods you can use to connect and communicate with different types of servers. One of the easiest ways is to use the cURL stands for client URLs, and it’s a library which allows you to send and receive information with the URL syntax. In fact, it leverages the libcurl library, created by Daniel Stenberg, which allows you to connect to and communicate with many different types of servers with many different types of protocols. Apart from HTTP and HTTPS, the libcurl library also supports protocols like FTP, Gopher, Telnet, DICT, File, and LDAP. From the next section onwards, we'll go through a couple of real-world examples to demonstrate how you can use cURL functions in PHP. Real-World ExamplesIn this section, we’ll build real-world examples to demonstrate various cURL functions in PHP. How to Download Files Using cURL in PHPReading or downloading remote files is one of the most common use cases for cURL. This is accomplished by a cURL GET request, which we’ll discuss in this section. Go ahead and create the curl_read_file.php file with the following contents.
All in all, it’s one of the best libraries to use when you want to make HTTP calls with different methods. In this section, we’ll discuss how to install Guzzle, followed up by a couple of quick examples to demonstrate the power of this library! How to Install the Guzzle LibraryThe official documentation recommends that you use Composer to install Guzzle. Let’s run the following command to install Guzzle in your project. $composer require guzzlehttp/guzzle:^7.0 ./composer.json has been created Loading composer repositories with package information Updating dependencies (including require-dev) Package operations: 6 installs, 0 updates, 0 removals - Installing psr/http-message (1.0.1): Loading from cache - Installing psr/http-client (1.0.1): Loading from cache - Installing ralouphie/getallheaders (3.0.3): Loading from cache - Installing guzzlehttp/psr7 (1.7.0): Loading from cache - Installing guzzlehttp/promises (1.4.1): Loading from cache - Installing guzzlehttp/guzzle (7.2.0): Loading from cache guzzlehttp/psr7 suggests installing laminas/laminas-httphandlerrunner (Emit PSR-7 responses) guzzlehttp/guzzle suggests installing psr/log (Required for using the Log middleware) Writing lock file Generating autoload files Once it’s installed, you need to require Composer's autoloader, as shown in the following snippet. require 'vendor/autoload.php'; And with that, you’re ready to use Guzzle! How to Make a GET Request With GuzzleIn this section, we’ll see how you can send GET requests with Guzzle. We’ll revise the example which we discussed earlier, as it will help you to understand how you could convert your existing cURL PHP code to a Guzzle-based implementation. Let’s have a look at the revised example. get('https://example.com'); $responseContents = $response->getBody(); Isn’t it straightforward? We’ve created an instance of the In our case, we need to fetch content with the GET method, so we’ve used the So that’s how you can perform HTTP GET requests with Guzzle. How to Make a POST Request With GuzzleIn this section, we’ll see how you can perform HTTP POST requests with Guzzle. We’ll revise the curl_post_example.php example, which we discussed in the earlier section. The revised code with Guzzle looks like this. [ "field_name_1" => "Value 1", "field_name_2" => "Value 2", "field_name_3" => "Value 3", ] ]; $response = $client->post("{POST_REST_ENDPOINT}", $options); $responseContents = $response->getBody(); ?> Since
this is a POST request, we need to pass the If you’re wondering how to post JSON data, you just need to change the Also, if you want to send any HTTP headers along with a request, you can do it with the ... ... $headers = array( 'Content-Type' => 'application/json' ); $options = [ 'form_params' => [ "field_name_1" => "Value 1", "field_name_2" => "Value 2", "field_name_3" => "Value 3", ], ‘headers’ => $headers ]; ... ... In fact, the Guzzle library provides a lot of configuration options for every method. Also, there are multiple ways to do the same thing, so I encourage you to explore it in detail, and I’m sure it will be fun! So that was a quick introduction to the Guzzle library, along with the PHP cURL functions. ConclusionToday, we explored the basics of the cURL extension in PHP. We discussed how you can perform different types of HTTP requests with cURL in PHP. Also, we went through a quick introduction to the Guzzle library, which makes life easier for developers when dealing with HTTP requests in PHP. Did you find this post useful?
