POST Requests with PHP: Reading Response Content

In your query, you express the need to send POST requests and read the subsequent response content using PHP. As GET requests are not accepted by the targeted URL, this article will guide you through the process of utilizing POST methods for this purpose.

Sending POST Requests with PHP

To initiate a POST request, consider employing the following PHP code:

$url = 'http://server.com/path';
$data = ['key1' => 'value1', 'key2' => 'value2'];

// use key 'http' even if you send the request to https://...
$options = [
    'http' => [
        'header' => "Content-type: application/x-www-form-urlencoded\r\n",
        'method' => 'POST',
        'content' => http_build_query($data),
    ],
];

$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
if ($result === false) {
    // Handle error
}

var_dump($result);

This code snippet illustrates how to create a stream context with specified HTTP options, including POST method, data submission, and relevant headers. It then uses the file_get_contents() function to retrieve the response content.

For more detailed information on the nuances of this method and incorporating additional headers, consult the PHP manual page: https://www.php.net/manual/en/function.stream-context-create.php
