a sample POST method with file_get_contents()

file_post_contents.php

<?php
if (!function_exists('http_post_contents')) {
	function http_post_contents($url, $params) {
				
		$content = http_build_query($params, '', '&');
		$header = array(
			"Content-Type: application/x-www-form-urlencoded",
			"Content-Length: ".strlen($content)
		);
		$options = array(
			'http' => array(
				'method' => 'POST',
				'content' => $content,
				'header' => implode("\r\n", $header)
			)
			
		);
		return file_get_contents($url, false, stream_context_create($options));
	}
}

And years later, still useful! Thanks.
