Question

I would like to know how to send a post request in curl and get the response page.

Answer 1

What about something like this :

$ch = curl_init();
$curlConfig = array(
    CURLOPT_URL            => "http://www.example.com/yourscript.php",
    CURLOPT_POST           => true,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_POSTFIELDS     => array(
        'field1' => 'some date',
        'field2' => 'some other data',
    )
);
curl_setopt_array($ch, $curlConfig);
$result = curl_exec($ch);
curl_close($ch);

// result sent by the remote server is in $result

For a list of options that can be used with curl, you can take a look at the page of curl_setopt.

Here, you’ll have to use, at least :

• CURLOPT_POST : as you want to send a POST request, and not a GET
• CURLOPT_RETURNTRANSFER : depending on whether you want curl_exec to return the result of the request, or to just output it.
• CURLOPT_POSTFIELDS : The data that will be posted — can be written directly as a string, like a querystring, or using an array

And don’t hesitate to read the curl section of the PHP manual 😉
