No PUT post data being received - php

Question

I am sending out a PUT request to my site via PHP using cURL:
$data = array("a" => 'hello');
$ch = curl_init('http://localhost/linetime/user/1');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
curl_setopt($ch, CURLOPT_POSTFIELDS,http_build_query($data));
$response = curl_exec($ch);
var_dump($response);
I am then listening for this PUT request, but receiving no data with the request. Please can you tell me where I am going wrong?
$putData = '';
$fp = fopen('php://input', 'r');
while (!feof($fp)) {
$s = fread($fp, 64);
$putData .= $s;
}
fclose($fp);
echo $putData;
exit;

Answer 1

make sure to specify a content-length header and set post fields as a string
$data = array("a" => 'hello');
$fields = http_build_query($data)
$ch = curl_init('http://localhost/linetime/user/1');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
//important
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Length: ' . strlen($fields)));
curl_setopt($ch, CURLOPT_POSTFIELDS,$fields);

Use an HTTP client class to help send the requests. There are several available, but I have created one (https://github.com/broshizzledizzle/Http-Client) that I can give you help with.
Making a PUT request:
<?php
require_once 'Http/Client.php';
require_once 'Http/Method.php';
require_once 'Http/PUT.php';
require_once 'Http/Request.php';
require_once 'Http/Response.php';
require_once 'Http/Uri.php';
use Http\Request;
use Http\Response;
header('Content-type:text/plain');
$client = new Http\Client();
//GET request
echo $client->send(
Request::create()
->setMethod(new Http\PUT())
->setUri(new Http\Uri('http://localhost/linetime/user/1'))
->setParameter('a', 'hello')
)->getBody();
?>
Processing a PUT request:
//simply print out what was sent:
switch($_SERVER['REQUEST_METHOD']) {
case 'PUT':
echo file_get_contents('php://input');
break;
}
Note that I have an autoloader on my projects that will load all those includes for me, but you may want to consider making a file that will include everything if you don't want to go down that route.
Library-less:
//initialization code goes here
$requestBody = http_build_query(
array('a'=> 'hello'),
'',
'&'
);
$fh = fopen('php://memory', 'rw');
fwrite($fh, $requestBody);
rewind($fh);
curl_setopt($this->curl, CURLOPT_INFILE, $fh);
curl_setopt($this->curl, CURLOPT_INFILESIZE, strlen($requestBody));
curl_setopt($this->curl, CURLOPT_PUT, true);
//send request here
fclose($fh);
Note that you use a stream to send the data.
