A basic CURL wrapper for PHP (see http://php.net/curl for more information about the libcurl extension for PHP)
Click the download link above or git clone git://github.com/shuber/curl.git
Simply require and initialize the Curl class like so:
require_once 'autoload.php';
$curl = new Curl;
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. The Curl object will append the array of $vars to the $url as a query string for all methods except POST.
$response = $curl->head($url, $vars = array());
$response = $curl->get($url, $vars = array());
$response = $curl->post($url, $vars = array());
$response = $curl->put($url, $put_data, $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(), $put_data = null);
All of the built in request methods like put and get simply wrap the request method. For example, the post method is implemented like:
function post($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.
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
<html>
<head>
<title>Google.com</title>
</head>
<body>
Some more html...
</body>
</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() method which will return the response body, so echo $response is the same as echo $response->body
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
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)
You can set custom headers to send with the request
$curl->setHeader('Host', 12.345.678.90);
$curl->setHeader('Some-Custom-Header', 'Some Custom Value');
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 for a list of them)
# any of these will work
$curl->setOption('AUTOREFERER', true);
$curl->setOption('CURLOPT_AUTOREFERER', true);
$curl->setOption(CURLOPT_AUTOREFERER, true);
Uses ztest, simply download it to path/to/curl/test/ztest (or anywhere else in your php include_path)
Then run test/runner.php
