Use Composer to manage HTTP libraries with curl_share support

Before using Composer, you need to make sure it is installed in your development environment. You can download and install Composer by visiting the official Composer website .

For Windows users, the installation process can be completed through Composer-Setup.exe, and Linux and macOS users can run the following commands from the command line:

 curl -sS https://getcomposer.org/installer | php

After the installation is completed, you can verify that Composer is installed successfully through the following command:

 composer --version

2. Create a project and initialize Composer

If you have not created a PHP project, you can initialize a new Composer project with the following command:

 composer init

Fill in the relevant information about the item according to the prompts. After initialization is completed, Composer will generate a composer.json file, which is used to record the project's dependency package and other configuration information.

3. Install the HTTP library that supports curl_share_init

Next, we need to select an HTTP library that supports the curl_share_init function. For example, guzzlehttp/guzzle is a popular HTTP client library that supports multiple features, including cURL session sharing.

We can install the Guzzle library through Composer:

 composer require guzzlehttp/guzzle

Composer automatically downloads the Guzzle library and all its dependencies and installs it into the vendor directory.

4. Share a session using Guzzle and curl_share_init

After installing the Guzzle library, you can start using it in PHP. Here is a simple example showing how to use curl_share_init to share sessions for multiple cURL requests.

 <?php

require 'vendor/autoload.php';

use GuzzleHttp\Client;

$shareHandle = curl_share_init(); // Initialize the shared handle

// create Guzzle Client
$client = new Client([
    'base_uri' => 'https://m66.net/',
    'curl' => [
        CURLOPT_SHARE => $shareHandle, // Pass the shared handle in
    ]
]);

// Make the first request
$response1 = $client->request('GET', 'example1');

echo $response1->getBody();

// Make a second request
$response2 = $client->request('GET', 'example2');

echo $response2->getBody();

// Close the shared handle
curl_share_close($shareHandle);
?>

In this example, we first initialize a cURL shared handle $shareHandle and then pass the shared handle to the Guzzle client through the curl configuration item of Guzzle. Each time a request is initiated, Guzzle uses the same shared session information to avoid duplicate network connections and authentication operations, thereby improving efficiency.

5. Other libraries that support curl_share_init

In addition to Guzzle, there are some other HTTP libraries that also support the curl_share_init function. For example, php-curl-class/php-curl-class is a simple and easy-to-use PHP cURL encapsulation library. It can also be used with curl_share_init , and the specific usage method is similar to Guzzle.

You can select the appropriate library according to project requirements and install it through Composer. For example, install php-curl-class :

 composer require php-curl-class/php-curl-class

Then use the shared session in the code in a similar way.

6. Summary

Composer manages HTTP libraries that support curl_share_init function, which can significantly improve the efficiency of HTTP requests in PHP applications. Composer provides an easy-to-use way to install, update, and manage third-party libraries, while curl_share_init allows us to share session information between multiple cURL requests, saving time and resources. In this article, we show how to install the Guzzle library and use curl_share_init to optimize HTTP requests. If you have more performance requirements, please try other HTTP libraries that support this function and adjust and optimize according to actual conditions.
