How to post data in PHP using file_get_contents?

To post data in PHP using file_get_contents, we can call file_get_contents with an options array.

For instance, we write

$postdata = http_build_query(array('var1' => 'some content', 'var2' => 'doh'));

$opts = array('http' => array('method' => 'POST', 'header' => 'Content-Type: application/x-www-form-urlencoded', 'content' => $postdata));

$context = stream_context_create($opts);
$result = file_get_contents('http://example.com/submit.php', false, $context);

to create the $postdata object with the form data parameter values.

We call http_build_query to build the query string.

Then we have the $opts array that sets the request method, request headers, and the content.

Then we call stream_context_create with $opts to create the $context object.

And then we call file_get_contents with the URL to make the request to and the $context object to make the request.

Finally, we get the response returned from file_get_contents and we assign it to $result.
