PHP cURL HTTP POST Example

In this article, we'll demonstrate how to send HTTP POST requests using PHP cURL.

Example Scenario:

We want to send the following data to www.example.com:

username=user1, password=passuser1, gender=1

and expect the cURL request to return a response like result=OK.

PHP Code Snippet:

// Initialize a cURL handle
$ch = curl_init();

// Set the URL to post to
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/tester.phtml");

// Enable POST method
curl_setopt($ch, CURLOPT_POST, true);

// Set the POST fields
$data = array('username' => 'user1', 'password' => 'passuser1', 'gender' => 1);
$post_fields = http_build_query($data);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields);

// Receive server response
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$server_output = curl_exec($ch);

// Close the cURL handle
curl_close($ch);

// Process the response
if ($server_output == "OK") {
    // Handle successful response
} else {
    // Handle error
}

This PHP cURL example sends the specified data to the remote server using the HTTP POST method. The server's response is stored in the $server_output variable. You can then process the response accordingly, checking if it matches the expected result=OK or handling any errors.
