Flexible wrapper class for PHP cURL extension

See for more information about the libcurl extension for PHP.

It's a fairly simple library, so if you want something more powerful take a look at Guzzle.


via Composer (recommended)

php composer.phar require svyatov/curlwrapper '~1.3'

via download

Just grab the latest release.



try {
    $curl = new CurlWrapper();
} catch (CurlWrapperException $e) {
    echo $e->getMessage();

Performing request

The CurlWrapper object supports 5 types of requests: HEAD, GET, POST, PUT, and DELETE. You must specify an url to request and optionally specify an associative array or query string of variables to send along with it.

$response = $curl->head($url, $params);
$response = $curl->get($url, $params);
$response = $curl->post($url, $params);
$response = $curl->put($url, $params);
$response = $curl->delete($url, $params);

To use a custom request methods, you can call the request method:

$response = $curl->request($url, 'ANY_CUSTOM_REQUEST_TYPE', $params);


$response = $curl->get('');

$response = $curl->get('', array('some_variable' => 'some_value'));
// CurlWrapper will append '&some_variable=some_value' to the url

$response = $curl->post('', array('title' => 'Test', 'body' => 'This is a test'));

All requests return response body as is or throw a CurlWrapperException if an error occurred.

Performing POST/PUT request with raw payload

Some times you need to send not encoded POST params, but a raw JSON or other raw data format.

$response = $curl->rawPost($url, $jsonData);
$response = $curl->rawPut($url, 'raw random data');

Note that data is sending as as, without any URL-encoding manipulation. Keep that in mind.

You might also need to change the content type header for those types of request:

$curl->addHeader('Content-Type', 'text/plain');
// or
$curl->addHeader('Content-Type', 'application/json');
// and then
$response = $curl->rawPost($url, $jsonData);

It depends on API server-side you are working with.

Getting additional information about request sent

$info = $curl->getTransferInfo();

This will give you associative array with following keys:

  • url - Last effective URL
  • content_type - Content-Type: of downloaded object, NULL indicates server did not send valid Content-Type: header
  • http_code - Last received HTTP code
  • header_size - Total size of all headers received
  • request_size - Total size of issued requests, currently only for HTTP requests
  • filetime - Remote time of the retrieved document, if -1 is returned the time of the document is unknown
  • ssl_verify_result - Result of SSL certification verification requested by setting CURLOPT_SSL_VERIFYPEER
  • redirect_count - Number of redirects it went through if CURLOPT_FOLLOWLOCATION was set
  • total_time - Total transaction time in seconds for last transfer
  • namelookup_time - Time in seconds until name resolving was complete
  • connect_time - Time in seconds it took to establish the connection
  • pretransfer_time - Time in seconds from start until just before file transfer begins
  • size_upload - Total number of bytes uploaded
  • size_download - Total number of bytes downloaded
  • speed_download - Average download speed
  • speed_upload - Average upload speed
  • download_content_length - content-length of download, read from Content-Length: field
  • upload_content_length - Specified size of upload
  • starttransfer_time - Time in seconds until the first byte is about to be transferred
  • redirect_time - Time in seconds of all redirection steps before final transaction was started
  • certinfo - There is official description for this field yet
  • request_header - The request string sent. For this to work, add the CURLINFO_HEADER_OUT option

You can also easily fetch any single piece of this array:

$httpCode = $curl->getTransferInfo('http_code');

Cookie sessions

To maintain a session across requests and cookies support you must set file's name where cookies to store:


This file must be writable or the CurlWrapperException will be thrown.

Basic configuration options

You can easily set the referer, user-agent, timeout and whether or not follow redirects:

$curl->setUserAgent('some user agent string');
$curl->setTimeout(15); // seconds
$curl->setFollowRedirects(true); // to follow redirects

HTTP Basic Authentication

You can set a username and password for use in HTTP basic auth:

$curl->setAuthCredentials('username', 'password');

Setting custom headers

You can set custom headers to send with the request:

$curl->addHeader('Host', '');
$curl->addHeader('Some-Custom-Header', 'Some Custom Value');

Or use a single array:

$curl->addHeader(array('Host'=>'', 'Some-Custom-Header'=>'Some Custom Value'));

Setting custom cURL options

You can set/override any cURL option (see the curl_setopt documentation for a list of them):

$curl->addOption(CURLOPT_AUTOREFERER, true);
