A little background, I'm passing a data-uri of an image, one of those
data:image/png;base64,iVBORw0KGgoAAAANSUhEUg
as a POST to a Nginx-HHVM server to be processed in PHP. Btw it works on PHP-FPM and not HHVM.
The POST passed in Javacript as an object is this:
{
data : data.uri,
transfer : community_header,
transfer_id 'f6d67f12-9de1-48c0-82e6-afdcfe97a031'
}
In PHP I get the data like so:
$data = file_get_contents("php://input");
if(is_string($data)){
$data = json_decode($data,true);
}
What is interesting is this is the result.
Array
(
[{"data":"data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAZAAAADICAYAAADGFbfiAAAgAElEQVR4Xuy9CbwlV1Uu/tVwhjvf2317TKfTmUMSEggyiIiKiCjDA1FBQMYAwgOZAhgIg8g8qaAs4QiAKwBk0JHWnU5xpyMoTLyBgbRYEHOT3KJMgeYiOziMhaVVmdNks1k5/0wglBeigCkNogj98vxzq10o0AEqZPz9HYiKyfRyaYudhN9nYLtQwtTkKOq2jY2tonKdhCbswWQmAs3Xw/8DWJkFg/A6MDIAAAAASUVORK5CYII] => ","transfer":"community_header","transfer_id":"f6d67f12-9de1-48c0-82e6-afdcfe97a031"}
)
Now I've truncated the data-uri for clarity by the array is really messed up and I cannot figure out. Does anyone have any insight?
This sounds like a bug, particularly if the result is different than with PHP-FPM. Can you file a bug on our GitHub issue tracker with the details, hopefully including an isolated repro case? It looks like you've already narrowed it down a lot, so hopefully getting an isolated repro isn't much work :)

I know this question has been asked millions of times, but please actually take the time to understand my problem before marking as duplicate or closing.
So I am using the following code. For some reason it gets all of the correct header information the first time I run the code EXCEPT for content-length. The second time I run the code it actually gets it correctly. I am retrieving the images from Facebook API if that changes anything.
function remote_filesize($url) {
$data = get_headers($url, 1);
if(isset($data['Content-Length'])) {
return (int) $data['Content-Length'];
}
else {
return -1;
}
}
Edit
Gotta love when you get downvoted with no explanation. Personally I think it should be required to provide a reason.
Anyway, this is still an issue, but in case anyone googling this needs a solution for getting the remote filesize, I would suggest using this awesome snippet from the PHP docs http://php.net/manual/en/function.filesize.php#114952
Sounds like a server caching issue.
So you may have to issue a full GET request instead of just a HEAD request.
Also, maybe check different casing -- 'content-length:' -- lowercase.
I'm trying out Azure Functions using PHP.
Getting the request information is not working for me.
I've not been able to find any documentation at all with the information of how to use Azure Functions with PHP code.
According to the only couple of examples, it seems that in order to retrieve the input information you need to first get the content of the req variable (or whatever name you assign in the function configuration).
That has the path of the file containing the request information (in theory).
$input_path = getenv('req');
So far, if I check the content of it, I get something like this:
D:\local\Temp\Functions\Binding\e2b6e195-02f7-481b-a279-eef6f82bc7b4\req
If I check if the file exists it says true, but the file size is 0.
Do anyone knows what to do here? Anyone with an example? Does anyone know where the documentation is?
Thanks
Ok, unfortunately there's pretty limited documentation out there for php as you have discovered.
At present, looking at the code might be the best doc. Here is the InitializeHttpRequestEnvironmentVariables function that adds request metadata to the environment for the script languages (node, powershell, php, python).
Important environment variables are:
REQ_ORIGINAL_URL
REQ_METHOD
REQ_QUERY
REQ_QUERY_<queryname>
REQ_HEADERS_<headername>
REQ_PARAMS_<paramname>
I'm assuming you've made a GET request, in which case there is no content (req is an empty file), but you will see that these other environment variables contain request data. If you were to make a POST request with a body then req would have data.
here is a full example parsing a GET request in PHP with an Azure Function :)
https://www.lieben.nu/liebensraum/2017/08/parsing-a-get-request-in-php-with-an-azure-function/
snippet from source:
<?php
//retrieve original GET string
$getReqString = getenv('REQ_QUERY');
//remove the ? for the parse_str function
$getReqString = substr($getReqString,1,strlen($getReqString));
//convert the GET string to an array
$parsedRequest = array();
parse_str($getReqString,$parsedRequest);
//show contents of the new array
print_r($parsedRequest);
//show the value of a GET variable
echo $parsedRequest["code"];
?>
I'm working with a very simple mock-up application to query a DB and display the results on a map. The application sends a GET httprequest to a server which returns a serialized array of value. The basic structure of the httprequest is:
httpRequest.open("GET","handle-query.php?query=" + queryJs)
and, on the other side:
$queryPhp = $_GET["query"];
When the query looks like this...
["SELECT%SUM(commit)%FROM%financialdata%WHERE%region='Centre'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%region='Kara'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%region='Maritime'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%region='Plateaux'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%region='Savanes'"]
...then it is passed to the server properly, and generates a response. However, when the query looks like this...
["SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Sotouboua'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Tchamba'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Tchaoudjo'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Assoli'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Bassar'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Bimah'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Doufelgou'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Keran'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Kozah'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Golfe'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Lacs'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Vo'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Yoto'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Zio'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Amou'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Haho'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Kloto'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Ogou'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Wawa'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Oti'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Tone'"]
...then the server receives an empty string. Both of the strings are generated by the same function, and both work perfectly on my virtual server (WAMP). If anyone has any ideas it would be greatly appreciated.
(P.S. After reading I realize that I should be using a framework with better sanitization, etc., but this is just a demo that will need to live online for maybe 2 hours, and it would be better to fix this small thing than start over. It works perfectly on my localhost.)
To actually answer your question, you're sending a get parameter as query (handle-query.php?query=) and then pulling it off as queryJS (queryJs).
$_GET['query'] // instead of $_GET['queryJs']
should do it.
(And as everyone has pointed out, don't send SQL in the clear or otherwise over the wire, unless you plan on not actually executing the SQL, and you just like to advertise your db structure, maybe it is that pretty.)
i need to do a "file_get_contents" on a URL and there has to be data posted to the url before the contents are retrieved. is this possible? maybe something like
$contents = file_get_contents($_POST"http://www.example.com/");
so that i can then work with the $contents variable?
You cannot*** POST data using file_get_contents, you must use something like cURL
* I mark this because it is actually possible taking advantage of the third parameter which uses http context(see example one). However it really isn't worth your trouble if you have something like cURL.
Ah, I have tried to do this. Simply put you can't unless you install new extra software on your sever and go through A LOT of hassel and server load.
Best bet is to use GET if at all possible!

Using twitterauth to try to post status updates. This is my code (which returns a 403 error from twitter when I try to post it):
$fact = "This is a status update. http://onth.is/iss" ;
$parameters = array('status' => $fact);
However, if I do this:
$parameters = array('status' => "This is a status update. http://onth.is/iss");
It post perfectly fine. I know it has something to do wit the URL, because if I remove it from the first code it works.
Any tips? Thanks in advance!
If you are referring to the twitteroath library then I don't see anything wrong with your code. However, you can speed things up a little bit by doing:
$parameters["status"] = "This is a status update. http://onth.is/iss";
The two statements are identical, except that the latter will create a syntax error :)
My guess would be that you need to urlencode() the string before sending it to Twitter, but not knowing the library you are using, I can't say for sure.
