Output Serialized JSON To String

I have data in this format:

[{"name":"Colour","value":"Green"},{"name":"Size","value":"Small"},{"name":"Thickness","value":"Narrow"}]

I use this line of code:

$decoded_options = json_decode($this->options);

To convert it to:

[
  {
    "name": "Colour",
    "value": "Green"
  },
  {
    "name": "Size",
    "value": "Small"
  },
  {
    "name": "Thickness",
    "value": "Narrow"
  }
]

I have then tried to loop over in various ways to output it (i.e):

$output = '';

foreach($decoded_options as $key => $value) {
    $output += (string) $value;
}

return $output;

None of my attempts have been successful. I wish to output the data in this format as a string:

name: Colour
value: Green

name: Size
value: Small

name: Thickness
value: Narrow

How would this be achieved?

You can do something below

Also replace += by .= because += will work in js not in php string.

$json = '[{"name":"Colour","value":"Green"},{"name":"Size","value":"Small"},{"name":"Thickness","value":"Narrow"}]';

$decoded_options = json_decode($json);



$output = '';

foreach($decoded_options as $key => $value) {

    $output .= 'name:  '. $value->name;
     $output .= PHP_EOL;
    $output .= 'value:  '. $value->value . PHP_EOL. PHP_EOL;
}

echo  $output;

How to serialize and deserialize JSON using C#, The JSON.stringify() method converts a JavaScript object or value to a JSON string, object that's used to insert white space into the output JSON string for can't be serialized in JSON") when trying to stringify a BigInt value. The quickest method of converting between JSON text and a .NET object is using the JsonSerializer.The JsonSerializer converts .NET objects into their JSON equivalent and back again by mapping the .NET object property names to the JSON property names and copies the values for you.

Try this, I have added second foreach which will give me the advantage to handle any number of elements in a single array.

$str = '[{"name":"Colour","value":"Green"},{"name":"Size","value":"Small"},{"name":"Thickness","value":"Narrow"}]
';

$dataArray = json_decode($str, true);
$outputString = "";
foreach($dataArray as $data) {
    foreach($data as $key => $element) {
        $outputString .= $key.": ".$element.PHP_EOL;
    }
    $outputString .= PHP_EOL;
}
echo $outputString;

JSON.stringify(), JSON is a format that encodes objects in a string. Serialization means to convert an object into that string, and deserialization is its inverse� but I need for the type of the objects to be included in the JSON string, like this: the type of an element is not standardly serialized, so you should add it

First of all use true as second parameter in json_decode to make sure you are getting an array back:

$decoded_options = json_decode($this->options, true);

Then simply look through, minding keys and create the string:

$output = '';

foreach($decoded_options as $value) {
    $output .= "name: {$value['name']} \n";
    $output .= "value: {$value['value']} \n\n";
}

return $output;

If you want to generalize it so that you don't hardcode name and value but use whatever comes as key, you can do so like this:

$output = '';

foreach($decoded_options as $value) {
    foreach ($value as $key => $v) {
        $output .= "$key: $v \n";
    }
    $output .= "\n";
}

return $output;
