Curly

Easy to use, general purpose CuRL wrapper

Basic usage

First require biohzrdmx/curly-php with Composer.

Now get an instance of Curly, prepare your request and execute it:

use Curly\Curly;

$curly = Curly::newInstance()
  ->setMethod('GET')
  ->setURL('https://api.icndb.com/jokes/random')
  ->setParams([ 'limitTo' => 'nerdy' ])
  ->execute();

Once executed you'll need to call the getResponse method to retrieve the Response object and use the data for whathever you like:

$response = $curly->getResponse();
if ($response && $response->getStatus() == 200) {
  $body = $response->getBody();
  if ($body->type == 'success') {
    echo $body->value->joke;
  }
} else {
  echo 'API error: ' . $curly->getError();
}

It's important to note that getBody will parse JSON and XML payloads if the response has a valid Content-Type header, but you may disable that by passing true as the first parameter to get a raw response body;

Also if the request fails you may call getError or getInfo to find the cause of the failure.

The Response object can also retrieve the value of a single header with the getHeader method or all the response headers via the getHeaders one.

As this internally uses the curl extension, it supports HTTPS out of the box if you have a properly configured server, but you may specify the location of you CA bundle by passing it as the first parameter in the newInstance call:

$cainfo = '/absolute/path/to/cacert.pem';
$curly = Curly::newInstance($cainfo);

Just grab a copy of cacert.pem from here and pass its absolute path. Curly will automatically honor your php.ini if its properly set there.

Downloading files

Starting from version 2.2 it's possible to stream file downloads directly to a file handle, to do so you will need to pass a resource before executing the request:

$resource = fopen('/absolute/path/to/file.zip', 'wb');
if ($resource) {
  $curly = Curly::newInstance()
    ->setMethod('GET')
    ->setResource($resource)
    ->setURL('https://my-web-app.com/assets/file.zip')
    ->execute();
  $response = $curly->getResponse();
  fclose($resource);
}

In this case the file data is written directly to the resource, so $response->getBody() will return an empty string, but you can check the status with $response->getStatus() and get the corresponding headers with $response->getHeader() and $response->getHeaders().

Remember to always close the file with fclose;

Uploading files

Also, there's support for file uploads with the CURLFile class,

use CURLFile;

$avatar = new CURLFile('/absolute/path/to/avatar.png');
$curly = Curly::newInstance()
  ->setMethod('POST')
  ->setURL('https://my-web-app.com/api/users/profile')
  ->setFields( ['email' => '[email protected]', 'avatar' => $avatar] )
  ->execute();

Just add your files like any other field and set the request method to POST, the class adjust everything automatically.
