Passing $_POST values with cURL

Should work fine.

$data = array('name' => 'Ross', 'php_master' => true);// You can POST a file by prefixing with an @ (for <input type="file"> fields)$data['file'] = '@/home/user/world.jpg';$handle = curl_init($url);curl_setopt($handle, CURLOPT_POST, true);curl_setopt($handle, CURLOPT_POSTFIELDS, $data);curl_exec($handle);curl_close($handle)

We have two options here, CURLOPT_POST which turns HTTP POST on, and CURLOPT_POSTFIELDS which contains an array of our post data to submit. This can be used to submit data to POST <form>s.

It is important to note that curl_setopt($handle, CURLOPT_POSTFIELDS, $data); takes the $data in two formats, and that this determines how the post data will be encoded.

1. $data as an array(): The data will be sent as multipart/form-data which is not always accepted by the server.

   $data = array('name' => 'Ross', 'php_master' => true);curl_setopt($handle, CURLOPT_POSTFIELDS, $data);

2. $data as url encoded string: The data will be sent as application/x-www-form-urlencoded, which is the default encoding for submitted html form data.

   $data = array('name' => 'Ross', 'php_master' => true);curl_setopt($handle, CURLOPT_POSTFIELDS, http_build_query($data));

I hope this will help others save their time.

• curl_setopt

Ross has the right idea for POSTing the usual parameter/value format to a url.

I recently ran into a situation where I needed to POST some XML as Content-Type "text/xml" without any parameter pairs so here's how you do that:

$xml = '<?xml version="1.0"?><stuff><child>foo</child><child>bar</child></stuff>';$httpRequest = curl_init();curl_setopt($httpRequest, CURLOPT_RETURNTRANSFER, 1);curl_setopt($httpRequest, CURLOPT_HTTPHEADER, array("Content-Type:  text/xml"));curl_setopt($httpRequest, CURLOPT_POST, 1);curl_setopt($httpRequest, CURLOPT_HEADER, 1);curl_setopt($httpRequest, CURLOPT_URL, $url);curl_setopt($httpRequest, CURLOPT_POSTFIELDS, $xml);$returnHeader = curl_exec($httpRequest);curl_close($httpRequest);

In my case, I needed to parse some values out of the HTTP response header so you may not necessarily need to set CURLOPT_RETURNTRANSFER or CURLOPT_HEADER.

Another simple PHP example of using cURL:

<?php    $ch = curl_init();                    // Initiate cURL    $url = "http://www.somesite.com/curl_example.php"; // Where you want to post data    curl_setopt($ch, CURLOPT_URL,$url);    curl_setopt($ch, CURLOPT_POST, true);  // Tell cURL you want to post something    curl_setopt($ch, CURLOPT_POSTFIELDS, "var1=value1&var2=value2&var_n=value_n"); // Define what you want to post    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // Return the output in string format    $output = curl_exec ($ch); // Execute    curl_close ($ch); // Close cURL handle    var_dump($output); // Show output?>

Instead of using curl_setopt you can use curl_setopt_array.
