PHP json_encode() results showing JSONLint errors - php

Question

I am having issues with validating the output of my json_encode() function.
I am pulling in an XML feed with cURL, converting it into an array, and converting that array into JSON with json_endode(). Ill spare you the cURL stuff:
foreach ($xmlObjects->articleResult as $articleResult) {
$article = array(
"articleResult" =>
array(
'articleId' => (string)$articleResult->articleId,
'title' => (string)$articleResult->title,
'subhead' => (string)$articleResult->subhead,
'tweet' => (string)$articleResult->tweet,
'publishedDate' => (string)$articleResult->publishedDate,
'image' => (string)$articleResult->image
),
);
$json = str_replace('\/','/',json_encode($article));
echo $json;
}
Which is giving me a JSON readout of:
{
"articleResult": {
"articleId": "0001",
"title": "Some title",
"subhead": "Some engaging subhead",
"tweet": "Check out this tweet",
"publishedDate": "January 1st, 1970",
"image": "http://www.domain.com/some_image.jpg"
}
}
{
"articleResult": {
"articleId": "0002",
"title": "Some title",
"subhead": "Some engaging subhead",
"tweet": "Check out this tweet",
"publishedDate": "January 1st, 1970",
"image": "http://www.domain.com/some_image.jpg"
}
}
This will give me a JSONLint error saying:
Parse error on line 10:
..._120x80.jpg" }}{ "articleResult
---------------------^
Expecting 'EOF', '}', ',', ']'
So naturally I will add in the comma, which gives me an End of File expectation:
Parse error on line 10:
..._120x80.jpg" }},{ "articleResu
---------------------^
Expecting 'EOF'
I am new to JSON, but I have checked the website and a few resources for proper JSON formatting and structure, and from what I can see my readout is following the guidelines. Any pointers?
Resources I've checked:
JSON.org naturally
Wikipedia has well documented page
W3Resource Had a good explanation of structure.

Answer 1

You were encoding 2+ objects into json string, you need [ ] to wrap them
the correct syntax is
[
{ /* first object */ }
, { /* second object */ }
, { /* third object */ }
]
the things you need to look out are
[ ] wrap
separate objects by comma
Solution
$json = array();
foreach ($xmlObjects->articleResult as $articleResult) {
$article = array(
"articleResult" =>
array(
'articleId' => (string)$articleResult->articleId,
'title' => (string)$articleResult->title,
'subhead' => (string)$articleResult->subhead,
'tweet' => (string)$articleResult->tweet,
'publishedDate' => (string)$articleResult->publishedDate,
'image' => (string)$articleResult->image
),
);
$json[] = $article;
}
echo json_encode($json);
