PHP script to dump full HTTP request to file (method, HTTP headers and body).

Yeah I also find that FILE_APPEND would be great so you can tail -f the log file and it does not get overwritten all the time. Apart from that, useful PHP snippet ;). THX

My edit to dump request to server log via php -S localhost:62000.

<?php

$time = time();
error_log("--------------------[START/" . $time . "]--------------------");
error_log("");
error_log(sprintf("%s %s %s", $_SERVER['REQUEST_METHOD'], $_SERVER['REQUEST_URI'], $_SERVER['SERVER_PROTOCOL']));
error_log("");
error_log("");
foreach ($_SERVER as $headerName => $headerValue) {
	if (preg_match('/^HTTP_/', $headerName)) {
		// convert HTTP_HEADER_NAME to Header-Name
		$headerName = strtr(substr($headerName, 5), '_', ' ');
		$headerName = ucwords(strtolower($headerName));
		$headerName = strtr($headerName, ' ', '-');

		error_log("$headerName: $headerValue");
	}
}
error_log("");
$body = file_get_contents('php://input');
$bodyLength = strlen($body);
error_log("");
error_log($bodyLength ? $body : "(empty body)");
error_log("");
error_log("---------------------[END/" . $time . "]---------------------");

Output

+1 for
file_put_contents($file, $content, FILE_APPEND | LOCK_EX);

I simplified the script by removing all of the unnecessary object oriented overhead, and made the log file append.
