How to forward $_POST with PHP and cURL?

Question

I receive POST request at my PHP script and would like to forward this post call to another script using POST too. How to do this? I can use cURL if it\'s required for this

Answer 1

If anyone needs this, here's a fully functional cURL request that re-routes $_POST where you want (based on ZZ coder's reply above)

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, "http://urlOfFileWherePostIsSubmitted.com");
    curl_setopt($ch, CURLOPT_POST, TRUE);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    // ZZ coder's part
    curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($_POST));
    $response = curl_exec($ch);
    curl_close($ch);

Answer 2

<?php

function executeCurl($arrOptions) {

    $mixCH = curl_init();

    foreach ($arrOptions as $strCurlOpt => $mixCurlOptValue) {
        curl_setopt($mixCH, $strCurlOpt, $mixCurlOptValue);
    }

    $mixResponse = curl_exec($mixCH);

    curl_close($mixCH);

    return $mixResponse;

}

// if need any http auth

$username = 'http-auth-username';
$password = 'http-auth-password';

$requestType = 'POST'; // this can be PUT or POST

// this can be $arrPostData = $_POST;
$arrPostData = array(
    'key1'  => 'value-1-for-k1y-1',
    'key2'  => 'value-2-for-key-2',
    'key3'  => array(
            'key31'   => 'value-for-key-3-1',
            'key32'   => array(
                'key321' => 'value-for-key321'
            )
    ),
    'key4'  => array(
        'key'   => 'value'
    )
);

// you can set your post data
$postData = http_build_query($arrPostData); // raw php array

$postData = json_encode($arrPostData); // Only USE this when request json data

$arrResponse = executeCurl(array(
    CURLOPT_URL => 'http://whatever-your-request-url.com/xyz/yii',
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_HTTPGET => true,
    CURLOPT_VERBOSE => true,
    CURLOPT_AUTOREFERER => true,
    CURLOPT_CUSTOMREQUEST => $requestType,
    CURLOPT_POSTFIELDS  => $postData,
    CURLOPT_HTTPHEADER  => array(
        "X-HTTP-Method-Override: " . $requestType,
        'Content-Type: application/json', // Only USE this when request json data
    ),
    // if required HTTP Authentication use below lines
    CURLOPT_HTTPAUTH => CURLAUTH_BASIC,
    CURLOPT_USERPWD  => $username. ':' . $password
));

Answer 3

Perhaps:

curl_setopt($ch, CURLOPT_POSTFIELDS, $_POST);

http://www.php.net/manual/en/function.curl-setopt.php

This can either be passed as a urlencoded string like 'para1=val1&para2=val2&...' or as an array with the field name as key and field data as value.

Answer 4

Do this,

curl_setopt($handle, CURLOPT_POSTFIELDS, http_build_query($_POST));
