How to loop through JSON array using PHP

Question

My PHP code:

$obj = json_decode($data);
print $obj->{\'name\'};

While it works for non-arrays, I can\'t for the life of me figure out h

Answer 1

I'm not sure what exactly you want but I guess you want print it just for debugging right now. You can try with print_r($obj); and var_dump($obj); - they must print something, especially var_dump(). When you see the data, you can easily edit function a little bit, so you can do for instance print_r($obj->reviews) or print_r($obj['reviews']), depending if $obj is object or array.

Answer 2

Here using objects example (to read reviews...raiting):

$jsonObject = json_decode($data);
foreach ($jsonObject->reviews as $data) {
    echo $data->rating;
}

Answer 3

You are probably having trouble because reviews is an array and you are trying to access it as a JSON object.

$obj = json_decode($data, TRUE);
for($i=0; $i<count($obj['reviews']); $i++) {
    echo "Rating is " . $obj['reviews'][$i]["rating"] . " and the excerpt is " . $obj['reviews'][$i]["excerpt"] . "<BR>";
}

Answer 4

You can use var_dump or print_r.

<?php 
$decodedJSON = json_decode($jsonData);

// Put everyting to the screen with var_dump;
var_dump($decodedJSON);

// With print_r ( useful for arrays );
print_r($decodedJSON);

// List just review ratings with foreach;
foreach($decodedJSON['reviews'] as $review){
    echo $review['rating'];
}
?>
