# curl



A basic CURL wrapper for PHP (see [http://php.net/curl](http://php.net/curl) for more information about the libcurl extension for PHP)



## Installation



Click the `download` link above or `git clone git://github.com/shuber/curl.git`



## Usage



### Initialization



Simply require and initialize the `Curl` class like so:



	require_once 'curl.php';

	$curl = new Curl;



### Performing a Request



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



	$response = $curl->head($url, $vars = array());

	$response = $curl->get($url, $vars = array()); # The Curl object will append the array of $vars to the $url as a query string

	$response = $curl->post($url, $vars = array());

	$response = $curl->put($url, $vars = array());

	$response = $curl->delete($url, $vars = array());



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



	$response = $curl->request('YOUR_CUSTOM_REQUEST_TYPE', $url, $vars = array());



All of the built in request methods like `put` and `get` simply wrap the `request` method. For example, the `post` method is implemented like:



	function post($url, $vars = array()) {

	    return $this->request('POST', $url, $vars);

	}



Examples:



	$response = $curl->get('google.com?q=test');



	# The Curl object will append '&some_variable=some_value' to the url

	$response = $curl->get('google.com?q=test', array('some_variable' => 'some_value'));

	

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



All requests return a CurlResponse object (see below) or false if an error occurred. You can access the error string with the `$curl->error()` method.



### The CurlResponse Object



A normal CURL request will return the headers and the body in one response string. This class parses the two and places them into separate properties.



For example



	$response = $curl->get('google.com');

	echo $response->body; # A string containing everything in the response except for the headers

	print_r($response->headers); # An associative array containing the response headers



Which would display something like



	

	

	Google.com

	

	

	Some more html...

	

	



	Array

	(

	    [Http-Version] => 1.0

	    [Status-Code] => 200

	    [Status] => 200 OK

	    [Cache-Control] => private

	    [Content-Type] => text/html; charset=ISO-8859-1

	    [Date] => Wed, 07 May 2008 21:43:48 GMT

	    [Server] => gws

	    [Connection] => close

	)

	

The CurlResponse class defines the magic [__toString()](http://php.net/__toString) method which will return the response body, so `echo $response` is the same as `echo $response->body`



### Cookie Sessions



By default, cookies will be stored in a file called `curl_cookie.txt`. You can change this file's name by setting it like this



	$curl->cookie_file = 'some_other_filename';



This allows you to maintain a session across requests



### Basic Configuration Options



You can easily set the referer or user-agent



	$curl->referer = 'http://google.com';

	$curl->user_agent = 'some user agent string';



You may even set these headers manually if you wish (see below)



### Setting Custom Headers



You can set custom headers to send with the request



	$curl->headers['Host'] = 12.345.678.90;

	$curl->headers['Some-Custom-Header'] = 'Some Custom Value';



### Setting Custom CURL request options



By default, the `Curl` object will follow redirects. You can disable this by setting:



	$curl->follow_redirects = false;



You can set/override many different options for CURL requests (see the [curl_setopt documentation](http://php.net/curl_setopt) for a list of them)



	# any of these will work

	$curl->options['AUTOREFERER'] = true;

	$curl->options['autoreferer'] = true;

	$curl->options['CURLOPT_AUTOREFERER'] = true;

	$curl->options['curlopt_autoreferer'] = true;



## Testing



Uses [ztest](http://github.com/jaz303/ztest), simply download it to `path/to/curl/test/ztest` (or anywhere else in your php include_path)



Then run `test/runner.php`
