I have this text in my $result

{"meta":{"code":400,"message":"Bad Request"},"error":"userId is required.","extras":null}

But when I do

$json_result = json_decode($result, true);

print_r($json_result);

It gives me null. I have validated this text everywhere and it says that it is a valid json.

EDIT

This is my code

<?php



$data = "&userId=";

$data_string = $data;

$url = 'http://apptellect.cloudapp.net/binance/api/v1/get_user_assets/';

$ch = curl_init($url);

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");

curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

echo $result = curl_exec($ch);

echo '<hr>';

curl_close($ch);

$json_result = json_decode($result, true);

echo json_last_error_msg();

echo '<hr>';

//$json_result = json_decode( preg_replace('/[x00-x1Fx80-xFF]/', '', $result), true );

print_r($json_result);

?>

I have solved this issue please check this below code

<?php

// Your code here!

$data = "&userId=";

$data_string = $data;

$url = 'http://apptellect.cloudapp.net/binance/api/v1/get_user_assets/';

$ch = curl_init($url);

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");

curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

echo $result = curl_exec($ch);

echo '<hr>';

curl_close($ch);



// This will remove unwanted characters.

// Check http://www.php.net/chr for details

for ($i = 0; $i <= 31; ++$i) { 

    $result = str_replace(chr($i), "", $result); 

}

$result = str_replace(chr(127), "", $result);



// This is the most common part

// Some file begins with 'efbbbf' to mark the beginning of the file. (binary level)

// here we detect it and we remove it, basically it's the first 3 characters 

if (0 === strpos(bin2hex($result), 'efbbbf')) {

   $result = substr($result, 3);

}



$json_result =    json_decode($result, true);



echo json_last_error_msg();

echo '<hr>';

print_r($json_result);



?>

I am sure it's work properly please check

Curl sent json response .it's display proper json but it's have unwanted characters. we have remove unwanted characters binary level.Then pass to json_decode function

Happy Programming

Hi I found that on stackoverflow: here

<?php



function removeBOM($data) {

    if (0 === strpos(bin2hex($data), 'efbbbf')) {

       return substr($data, 3);

    }

    return $data;

}



$data = "&userId=";

$data_string = $data;

$url = 'http://apptellect.cloudapp.net/binance/api/v1/get_user_assets/';

$ch = curl_init($url);

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");

curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);



$result = curl_exec($ch);

$result = removeBOM($result);

echo $result;



curl_close($ch);

$json_result = json_decode(trim($result), false);

echo json_last_error_msg();

//$json_result = json_decode( preg_replace('/[x00-x1Fx80-xFF]/', '', $result), true );

print_r($json_result);

?>

just you need to add the trim before decoding your code.You will get the result as it is getting some extra data
