PHP + curl, HTTP POST sample code?

Question

Can anyone show me how to do a php curl with an HTTP POST? I want to send data like this: username=user1, password=passuser1, gender=1 To `www.domain.com` I expect the curl to return a response like `result=OK`. Are there any examples?

Sure! Here's an example of how to use PHP's curl library to make an HTTP POST request with the data you provided:

<?php

// Set the URL you want to post to

$url = 'http://www.domain.com';

// Set the data you want to send

$data = array(

   'username' => 'user1',

   'password' => 'passuser1',

   'gender' => '1'

);

// Initialize curl

$ch = curl_init();

// Set the curl options

curl_setopt($ch, CURLOPT_URL, $url);

curl_setopt($ch, CURLOPT_POST, true);

curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// Execute the curl request

$response = curl_exec($ch);

// Close the curl handle

curl_close($ch);

// Display the response

echo $response;

?>

In this example, we first set the URL we want to post to ($url) and the data we want to send ($data). We then initialize curl ($ch) and set the curl options using curl_setopt(). Specifically, we set the URL, set the request method to POST, set the data to be sent using http_build_query(), and set CURLOPT_RETURNTRANSFER to true to make sure curl returns the response instead of outputting it directly.

After setting the options, we execute the curl request using curl_exec() and store the response in $response. Finally, we close the curl handle using curl_close() and display the response using echo.

This should be enough to make an HTTP POST request with the data you provided and get a response back.
