make sure your data is UTF-8 and also check if you have foreign characters.

blocks|key|294228|text|我遇到了同样的问题，实际上有一些隐藏的字符是看不见的，你需要删除它。以下是适用于多种情况的全局代码：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|294229|<?php

I faced the same issue, actually there are some hidden characters unseen and you need to remove it.
Here's a global code that works for many cases:

<pre><code>&lt;?php
$checkLogin = file_get_contents("http://yourwebsite.com/JsonData");

// This will remove unwanted characters.
// Check http://www.php.net/chr for details
for ($i = 0; $i &lt;= 31; ++$i) { 
 $checkLogin = str_replace(chr($i), "", $checkLogin); 
}
$checkLogin = str_replace(chr(127), "", $checkLogin);

// 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($checkLogin), 'efbbbf')) {
 $checkLogin = substr($checkLogin, 3);
}

$checkLogin = json_decode( $checkLogin );
print_r($checkLogin);
?&gt;
</code></pre>

Removing the <code>BOM</code> (Byte Order Mark) is often-times the solution you need:

<pre><code>function removeBOM($data) {
 if (0 === strpos(bin2hex($data), 'efbbbf')) {
 return substr($data, 3);
 }
 return $data;
}
</code></pre>

You shouldn't have a BOM, but if it's there, it is invisible so you won't see it!!

see <a href="http://www.w3.org/International/questions/qa-byte-order-mark.en.php" rel="noreferrer">W3C on BOM's in HTML</a>

use <a href="https://github.com/emrahgunduz/BomCleaner/blob/master/bom.php" rel="noreferrer">BOM Cleaner</a> if you have lot's of files to fix.

A JSON string must be double-quoted, the JSON isn't valid because you don't need to escape <code>'</code> character.

<pre><code>char = unescaped /
 escape (
 %x22 / ; " quotation mark U+0022
 %x5C / ; \ reverse solidus U+005C
 %x2F / ; / solidus U+002F
 %x62 / ; b backspace U+0008

 %x72 / ; r carriage return U+000D
 %x74 / ; t tab U+0009
 %x75 4HEXDIG ) ; uXXXX U+XXXX
</code></pre>

The <code>'</code> is not in the list.

See this list of special character used in JSON:

<pre><code>\b Backspace (ascii code 08)
\f Form feed (ascii code 0C)
\n New line
\r Carriage return
\t Tab
\" Double quote
\\ Backslash character

I got a very strange problem.

I have a JSON webservice.

When i check it with this website <a href="http://www.freeformatter.com/json-formatter.html#ad-output" rel="noreferrer">http://www.freeformatter.com/json-formatter.html#ad-output</a>

Everything is OK.

But when i load my JSON with this code :

<pre><code> $data = file_get_contents('http://www.mywebservice');

if(!empty($data))
{

 $obj = json_decode($data);

 switch (json_last_error()) {

 break;
 case JSON_ERROR_UTF8:
 echo ' - JSON_ERROR_UTF8';
 break;
 default:
 echo ' - Unknown erro';
 break;
}
</code></pre>

I got the error : SYNTAX ERROR

WHICH IS NOT HELP FULL AT ALL.

It is a nightmare. 

I see that with PHP 5.5 i could use this function : <a href="http://php.net/manual/en/function.json-last-error-msg.php" rel="noreferrer">http://php.net/manual/en/function.json-last-error-msg.php</a>

(but i did not succeed to install PHP 5.5 yet, and i m not sure this function will give me more detail)

json_decode returns JSON_ERROR_SYNTAX but online formatter says the JSON is OK
