InitPHP Curl

Curl library to help you make advanced HTTP requests with PHP.

Requirements

• PHP 7.4 or higher
• PHP Curl Extension

Installation

composer require initphp/curl

Usage

require_once "vendor/autoload.php";
use \InitPHP\Curl\Curl;

$curl = new Curl();
$curl->setUrl("https://example.com");
$curl->handler();
    
$res = $this->getResponse();

if(!empty($curl->getError())){
    die($curl->getError());
}
echo $res['body'];

This library can be used as HTTP client for your API service. Example:

require_once "vendor/autoload.php";
use \InitPHP\Curl\Curl;

$curl = Curl::client('PUT', 'http://api.service.example.com/update/1')

$curl->setVersion("1.1") // HTTP Version
    ->setHeader("Content-Type", "application/json")
    ->setBody(json_encode([
        'username'  => 'admin',
        'password'  => '12345',
    ]))
    ->handler();

if(!empty($curl->getError())){
    die($curl->getError());
}

switch ($curl->getResponse('code')) {
    case 200 :
    case 201 :
        // Success
        break;
    case 404 :
        // Not Found
        break;
    case 400:
        // Badrequest
        break;
    // ...
}
