How to Post Data with cURL in PHP

Do you need to post data to a website using PHP? It’s actually pretty easy to do. Here’s the code.

<?php
$urltopost = "http://somewebsite.com/script.php";
$datatopost = array (
"firstname" => "Mike",
"lastname" => "Lopez",
"email" => "my@email.com",
);

<span id="more-40"></span>

$ch = curl_init ($urltopost);
curl_setopt ($ch, CURLOPT_POST, true);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $datatopost);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
$returndata = curl_exec ($ch);
?>

And what happened? Here’s my quick explanation.

$urltopost

The url where you want to post your data to

$datatopost

The post data as an associative array. The keys are the post variables

$ch = curl_init ($urltopost);

Initializes cURL

curl_setopt ($ch, CURLOPT_POST, true);

Tells cURL that we want to send post data

curl_setopt ($ch, CURLOPT_POSTFIELDS, $datatopost);

Tells cURL what are post data is

curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);

Tells cURL to return the output of the post

$returndata = curl_exec ($ch);

Executes the cURL and saves theoutput in $returndata
