parsing json_decode output null - php

I have tried to parse one variable from json decoded variable, i always got null, i even tried to encode to utf-8.
My code:
<?php
$url = 'https://ots-list.org/ajax/getServers';
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'method' => 'POST',
'content' => 'server_name=Return+of+Sayians&game_type=---&client_version=---&server_country=---'
)
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
if ($result === FALSE) { /* Handle error */ }
//var_dump($result);
$string = mb_convert_encoding($result, "UTF-8");
$data = json_decode($string);
print $data->{'players_online'};
?>

PHP file get html doesnt return anything

include('simple_html_dom.php');
$html = file_get_html("https://www.psacard.com/cert/43696531");
echo $html;
This will not print anything out for me, but I will get it from other websites. Any specific reason why?
file_get_contents also returns nothing.
$url = "https://www.psacard.com/cert/43696531";
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'method' => 'GET',
)
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
$string = preg_replace('/\s+/S', " ", $result);
if ($result === FALSE) { /* Handle error */ }
$stringVal = strval($string);
echo $stringVal;

Error 400 with PATCH method using PHP stream_context_create function to pass JSON data to API

I am trying to post to this Microsoft API but I'm getting an Error 400. Works fine when using their browser-based API test console and in Postman but I can't get it working using my PHP code below. Where am I going wrong?
$myObj->update->name = "API test";
$myObj->update->qnaList->qnaId = "331";
$myObj->update->qnaList->answer = "I have been updated";
$myObj->update->qnaList->source = "Editorial";
$myObj->update->qnaList->questions->add = "What is your name";
$myObj->update->qnaList->metadata->add->name = "category";
$myObj->update->qnaList->metadata->add->value = "personality";
$data = json_encode($myObj);
$url = '[https://apiurl]';
$options = array(
'http' => array(
'method' => 'PATCH',
'content' => $data,
'header' => "Content-Type: application/json\r\n" .
"Ocp-Apim-Subscription-Key: [mykey]"
)
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
$response = json_decode($result, true);
print_r($response);

There are problems with the JSON body you are trying to send.
This works for me and returns 204:
<?php
$myObj->update->name = "API test";
$myObj->update->qnaList = array();
$myObj->update->qnaList[0]->qnaId = "1";
$myObj->update->qnaList[0]->answer = "I have been updated";
$myObj->update->qnaList[0]->source = "Editorial";
$myObj->update->qnaList[0]->questions->add = array();
$myObj->update->qnaList[0]->questions->add[0] = "What is your name";
$myObj->update->qnaList[0]->metadata->add = array();
$myObj->update->qnaList[0]->metadata->add[0]->name = "category";
$myObj->update->qnaList[0]->metadata->add[0]->value = "personality";
$data = json_encode($myObj);
$kbid = "<YOUR-KB-ID>";
$url = 'https://westus.api.cognitive.microsoft.com/qnamaker/v3.0/knowledgebases/' . $kbid;
$options = array(
'http' => array(
'ignore_errors' => true,
'method' => 'PATCH',
'content' => $data,
'header' => "Content-Type: application/json\r\n" .
"Ocp-Apim-Subscription-Key: <YOUR-KEY>\r\n"
)
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
$response = json_decode($result, true);
echo $response . "\r\n";
?>

PHP code not returning response from other site

I am using 000webhosting.com. I have uploaded a file check.php
<?php
$url = 'http://www.otherdomain.com/login/?';
$data = array('user' => 'admin',
'pass' => 'password');
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'method' => 'POST',
'content' => http_build_query($data)
)
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
if ($result === FALSE) { /* Handle error */ }
var_dump($result);
?>
When i call www.000webhosting.com/check.php, it returns string(0) ""
Whereas , when i upload check.php in allcodez.com and call www.allcodez.com/check.php, it returns {"status":"true", "login":"true"}.
Is the problem with 000webhosting.com settings? or any other?

php post json text AND image in base64

I try to send text and an image in base64 via the post method.
There is my code:
// $question is just text, and $photo_base64 is a photo (.png) encode in base64 with the javascript function btoa()
function get_iframe($question, $token, $photo_base64){
$url = 'http://www.squareoffs.com/api/v1/squareoffs?auth_token=' . $token;
$data = array('question' => $question);
$data['photo'] = 'data:image/png;base64,' . $photo_base64;
$data = json_encode($data);
$options = array(
'http' => array(
'header' => "Content-Type: application/json\r\n" .
"Accept: application/json\r\n",
'method' => 'POST',
'content' => $data
)
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
return json_decode($result);
}
But when a taste it (with correct argument), it does not work, the function return false instead of a json file.
Does someone have a hint?
Thank you very much!

PHP - Posting JSON via file_get_contents

I am trying to POST JSON content to a remote REST endpoint, however the 'content' value appears to be empty on delivery. All other headers etc are being received correctly, and the web service tests successfully with a browser based test client.
Is there a problem with my syntax below where I specify the 'content' field?
$data = array("username" => "duser", "firstname" => "Demo", "surname" => "User", "email" => "example#example.com");
$data_string = json_encode($data);
$result = file_get_contents('http://test.com/api/user/create', null, stream_context_create(array(
'http' => array(
'method' => 'POST',
'header' => array('Content-Type: application/json'."\r\n"
. 'Authorization: username:key'."\r\n"
. 'Content-Length: ' . strlen($data_string) . "\r\n"),
'content' => $data_string)
)
));
echo $result;

This is the code I always use and it looks pretty similar (though this is of course for x-www-form-urlencoded).
Perhaps your username:key needs to be base64_encode'd.
function file_post_contents($url, $data, $username = null, $password = null)
{
$postdata = http_build_query($data);
$opts = array('http' =>
array(
'method' => 'POST',
'header' => 'Content-type: application/x-www-form-urlencoded',
'content' => $postdata
)
);
if($username && $password)
{
$opts['http']['header'] .= ("Authorization: Basic " . base64_encode("$username:$password"));
}
$context = stream_context_create($opts);
return file_get_contents($url, false, $context);
}

The question was about json, why the accepted answer is about x-www-form?
Json has many cool stuff to struggle about, like utf8_encode
function my_utf8_encode(array $in): array
{
foreach ($in as $key => $record) {
if (is_array($record)) {
$in[$key] = my_utf8_encode($record);
} else {
$in[$key] = utf8_encode($record);
}
}
return $in;
}
function file_post_contents(string $url, array $data, string $username = null, string $password = null)
{
$data = my_utf8_encode($data);
$postdata = json_encode($data);
if (is_null($postdata)) {
throw new \Exception('decoding params');
}
$opts = array('http' =>
array(
'method' => 'POST',
'header' => 'Content-type: application/json',
'content' => $postdata
)
);
if (!is_null($username) && !is_null($password)) {
$opts['http']['header'] .= "Authorization: Basic " . base64_encode("$username:$password");
}
$context = stream_context_create($opts);
try {
$response = file_get_contents($url, false, $context);
} catch (\ErrorException $ex) {
throw new \Exception($ex->getMessage(), $ex->getCode(), $ex->getPrevious());
}
if ($response === false) {
throw new \Exception();
}
return $response;
}

The earlier response of
function file_post_contents($url, $data, $username = null, $password = null) {
$postdata = http_build_query($data);
$opts = array('http' =>
array(
'method' => 'POST',
'header' => 'Content-type: application/x-www-form-urlencoded',
'content' => $postdata
)
);
if($username && $password)
{
$opts['http']['header'] = ("Authorization: Basic " . base64_encode("$username:$password"));
}
$context = stream_context_create($opts);
return file_get_contents($url, false, $context);}
is incorrect. This function works sometimes, but it is inaccurate and will fail if you're not using the Content-type of application/x-www-form-urlencoded and you pass in a username and password.
It's working for the writer because application/x-www-form-urlencoded is the default Content-type, but his handling of the username and password is overwriting the earlier declaration of content type.
Here is the corrected function:
function file_post_contents($url, $data, $username = null, $password = null){
$postdata = http_build_query($data);
$opts = array('http' =>
array(
'method' => 'POST',
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'content' => $postdata
)
);
if($username && $password)
{
$opts['http']['header'] .= ("Authorization: Basic " . base64_encode("$username:$password")); // .= to append to the header array element
}
$context = stream_context_create($opts);
return file_get_contents($url, false, $context);}
Note the line:
$opts['http']['header' .= (dot equals to append to the array element.)
