Not able to parse json node with json_decode() in php

Question

here is the json string in the variable which i am trying to parse with json_decode() function. I am trying to retrieve a specific node information with it but its showing me the blank white page. want to try with the file_get_contents() also to get json string from outer file. I have alreay seen the answer on the previous questions but that didn't helped me

<?php
//$json = file_get_contents('jsonfile.json');
$json = '[
{
    "selfie": {
        "post_author": "2",
        "post_date": "2014-12-02 13:00:00",
        "post_date_gmt": "2014-12-02 13:00:00",
        "post_content": "this is an example content",
        "image": "http://ssomesite.com/webservice/uploads/support.jpg",
        "post_title": "TestJSON"
    }
}
]';
$result = json_decode ($json);
echo $result->selfie->post_date;
//echo $result->selfie;
?>

Answer 1

echo $result[0]->selfie->post_date;

Answer 2

Your object path is wrong. It should be

echo $result[0]->selfie->post_date;

...because the JSON begins with an array, of which your selfie definition is in the first element, hence [0] .

Answer 3

Your JSON format defines an array, containing a single object, with a single property called selfie , you need to access the data like so:

echo $result[0]->selfie->post_date;

If ever a JSON string cannot be parsed, the best thing to do is check what json_last_error and json_last_error_msg tell you abot what went wrong.

Answer 4

I think you are missing that parent array. You need to consider the array also:

<?php
$json = '[
{
    "selfie": {
        "post_author": "2",
        "post_date": "2014-12-02 13:00:00",
        "post_date_gmt": "2014-12-02 13:00:00",
        "post_content": "this is an example content",
        "image": "http://ssomesite.com/webservice/uploads/support.jpg",
        "post_title": "TestJSON"
    }
}
]';
$result = json_decode ($json);
print($result[0]->selfie->post_date);
?>

Demo

Answer 5

That's an array object. Instead of using $result->selfie->post_date . Use:

var_dump($result[0]->selfie->post_date);

Answer 6

<?php
//$json = file_get_contents('jsonfile.json');
$json = '[
{
    "selfie": {
        "post_author": "2",
        "post_date": "2014-12-02 13:00:00",
        "post_date_gmt": "2014-12-02 13:00:00",
        "post_content": "this is an example content",
        "image": "http://ssomesite.com/webservice/uploads/support.jpg",
        "post_title": "TestJSON"
    }
}
]';
$result = json_decode ($json,true);
$rs = (array)$result;
echo '<pre>';
print_r($rs);
die;
?>

Array
(
    [0] => Array
        (
            [selfie] => Array
                (
                    [post_author] => 2
                    [post_date] => 2014-12-02 13:00:00
                    [post_date_gmt] => 2014-12-02 13:00:00
                    [post_content] => this is an example content
                    [image] => http://ssomesite.com/webservice/uploads/support.jpg
                    [post_title] => TestJSON
                )

        )

)

Answer 7

After researching a lot i found that the file_get_contents() is actually getting data from the file but due to its encoding its having some junk character before json like this 

so for this i changed the encoding to utf8 (BOM or without BOM) and its works fine now.

with the json string in the same file was already answered by @rut2 and other developes too. I appreciate their effort to solve my problem.
