Json Object to PHP array - not converting

Question

I am trying to take a json object stored in a textarea and convert it into a php array. I assign the value of the textarea to variable like $data = $_POST[‘data’] . When I submit the value of the text I use json_decode($data, true) to convert from JSON Object to php array. But nothing happens. It seems like nothing is assigned. How can I achieve the above?

EDIT: I have added quotes and made the suggestion below and is not working: DEMO

PHP

if(isset($_POST['submit'])) {
$data = $_POST['data'];
$personArray = json_decode($data, true);
print_r($personArray);
}

HTML

<textarea name="data">[{
    "firstName": "Jenny",
    "lastName": "LaRusso",
    "phone": "(555) 121-2121",
    "alt_phone": "(555) 123-4567",
    "main1": false,
    "main2": true    
}, {
    "firstName": "Sensei",
    "lastName": "Miyagi",
    "phone": "(555) 444-2222",
    "alt_phone": "(555) 999-1212",
    "main1": true,
    "main2": false
}]</textarea>

Just curious. Did you notice your textarea content before submit? — Your Common Sense

HTML looks nice, but have you inspected what $_POST['data'] contains? That's the data you're dealing with, regardless of where it came from. — GolezTrol

Second that. Try printing out your input before it is parsed. var_dump($_POST['data']) should do. — Aurea

side note, validation in most cases is very important, here is a great solution for validating the json in the texarea: stackoverflow.com/questions/6041741/… — m79lkm

I think in proper JSON, the keys (like firstName) need also be enclosed in quotes.

Are you sure? That JSON is valid now, according to jsonlint.com, so maybe the (next) problem is somewhere else.

Change your PHP code to

if(isset($_POST['data'])) {
$data = $_POST['data'];
$data = stripslashes($data); //Stripslashes removes all backslashes :)
$personArray = json_decode($data, true);
print_r($personArray);
}

Your JSON object should be this way inside the textarea

[{
"firstName": "Jenny",
"lastName": "LaRusso",
"phone": "(555) 121-2121",
"alt_phone": "(555) 123-4567",
"main1": false,
"main2": true    
}, {
"firstName": "Sensei",
"lastName": "Miyagi",
"phone": "(555) 444-2222",
"alt_phone": "(555) 999-1212",
"main1": true,
"main2": false
}]

Happy Coding :)

OOPS, I forgot about the limitations of using "" in your text. I have edited the answer above :)

There does not seem to be anything wrong with your PHP code. For debugging, after setting $personArray, try adding these two lines:

var_dump($data);
var_dump($personArray);

This should lead to why you are having trouble.

Here you can see what each return type means(if $returnArray is equal to false): http://php.net/json_decode
