How can I send HTTP POST requests in PHP?

To send HTTP POST requests in PHP, you can use the cURL library which allows you to communicate with other servers. You need to set the CURLOPT_POST option to true and provide the data you want to send in the CURLOPT_POSTFIELDS option. Finally, execute the request using curl_exec(). 

$url = 'http://example.com/api';
$data = array('key1' => 'value1', 'key2' => 'value2');

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);

if($response === false){
    echo 'cURL error: ' . curl_error($ch);
} else {
    echo $response;
}

curl_close($ch);
