json from string to array using php - php

Question

I have a problem with json parsing.
I have already read the many questions here on stackoverflow but I can't figured out what I'm missing.
In my site I use Facebook Api to post my feed using curl and it respond with a json message.
I take this response and I save it in my database.
In my Backoffice I need to retrieve this message and print it in case of error.
Here an example about an error message:
{"error":{"message":"(#1500) The url you supplied is invalid","type":"OAuthException","code":1500}}
In my php page I need to get just the message part so I did:
$message = get from the db and fetch;
$error_array = json_decode($message,true);
print_r($error_array);
but it doesn't print anything, just a blank page.
If I just print $message I can see the entire string.
What am I missing?
This issue it's driving me crazy all day long!!

Answer 1

I tried the following:
<pre>
<?php
$jsonStr = '{"error":{"message":"(#1500) The url you supplied is invalid","type":"OAuthException","code":1500}}';
$error_array = json_decode($jsonStr, true);
print_r($error_array);
?>
and getting output:
Array
(
[error] => Array
(
[message] => (#1500) The url you supplied is invalid
[type] => OAuthException
[code] => 1500
)
)
It's working as intended.
I suspect the problem is with this:
$message = get from the db and fetch;
After you load the $message variable, do a var_dump($message) and see if the string is in there (as expected).

Answer 2

$jsonString = '["m#gmail.com","b#gmail.com","c#gmail.com"]';
$arrayOfEmails=json_decode($jsonString);
Or
$jsonString = "[\"a#gmail.com\",\"b#gmail.com\",\"c#gmail.com\"]";
$arrayOfEmails=json_decode($jsonString);
