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

dumprequest.php

<?php
// https://gist.github.com/magnetikonline/650e30e485c0f91f2f40

class DumpHTTPRequestToFile {
	public function execute($targetFile) {
		$data = sprintf(
			"%s %s %s\n\nHTTP headers:\n",
			$_SERVER['REQUEST_METHOD'],
			$_SERVER['REQUEST_URI'],
			$_SERVER['SERVER_PROTOCOL']
		);

		foreach ($this->getHeaderList() as $name => $value) {
			$data .= $name . ': ' . $value . "\n";
		}

		$data .= "\nRequest body:\n";

		file_put_contents(
			$targetFile,
			$data . file_get_contents('php://input') . "\n"
		);

		echo("Done!\n\n");
	}

	private function getHeaderList() {
		$headerList = [];
		foreach ($_SERVER as $name => $value) {
			if (preg_match('/^HTTP_/',$name)) {
				// convert HTTP_HEADER_NAME to Header-Name
				$name = strtr(substr($name,5),'_',' ');
				$name = ucwords(strtolower($name));
				$name = strtr($name,' ','-');

				// add to list
				$headerList[$name] = $value;
			}
		}

		return $headerList;
	}
}


(new DumpHTTPRequestToFile)->execute('./dumprequest.txt');

Request body:

Hey ! Thanks for this helpfull script !
My suggestions :

• remove 'echo("Done!\n\n");' : user of this script should be able to have control of what is written to the request output
• change $data .= "\nResponse body:\n"; to $data .= "\nRequest body:\n"; ? Since what you dump is the body of the actual request, not the response

@beebopfr Request body of course 👍 Thanks!

Hello,

It's a very useful script would be useful if it can dump
$_GET
data as well and also list
$_SERVER['REMOTE_ADDR']

Nice script, thank you!

hi ,
am how to use this script to get the response ???

thanks in advance

To add every new register instead of replacing the previous one, you must use FILE_APPEND with file_get_content.
$data . file_get_contents('php://input') . "\n*************************************************************\n", FILE_APPEND
Thank you.

Use this line to get GET/POST data

$data . print_r($_REQUEST,true) . "\n*************************************************************\n", FILE_APPEND

add this line at the end to create a file for each request with timestamp

$date = new DateTime();
rename("dumprequest.txt", "dumprequest" . $date->format('Y-m-d H:i:sP') . ".txt");

This doesn't need to be a class, could be a easy to use library function.

Hey! thanks for this script.

I'm a complete newbie and maybe I can not even explain myself. However what I need is to save data coming from an http request to my server on a file. Thus it seems that the above script is perfect for my needs.
What I do not understand is where to put the script and how let it works: should I put the script on my server and use is URL in the http request to let him works and create the file?

thanks in advance

For the next time I come across this- Single function version.

function logRequest($targetFile){ $headerList = []; foreach ($_SERVER as $name => $value) { if (preg_match('/^HTTP_/',$name)) { // convert HTTP_HEADER_NAME to Header-Name $name = strtr(substr($name,5),'_',' '); $name = ucwords(strtolower($name)); $name = strtr($name,' ','-'); $headerList[$name] = $value; } } $data = sprintf("%s %s %s\n", $_SERVER['REQUEST_METHOD'], $_SERVER['REQUEST_URI'], $_SERVER['SERVER_PROTOCOL']); foreach ($headerList as $name => $value) { $data .= $name.': '.$value."\n"; } $data .= "\n"; file_put_contents($targetFile, $data.file_get_contents('php://input')."\n"); }

logRequest("/tmp/post-".time().".log");

@jotham thanks for summarizing it

Simple, but useful snippet. :)

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.
