JSON_NUMERIC_CHECK and phone numbers

Question

Our PHP API outputs results using json_encode with JSON_NUMERIC_CHECK enabled, which is important for financial figures, binary values etc.. but we have recently introduced

Answer 1

You can try this:

{
  "is_bool": 1,
  "total_amount": 431.65,
  "phone_number": "xn#0272561313"
}

as example in mysql: SELECT CONCAT('xn#', phone_number) as phone_number...

If you used json_encode(), replace the string like this:

echo str_replace('xn#','',$your_encoded_json);

Answer 2

For what it's worth, I had a similar problem in that I have international phone numbers starting with a + symbol. I used urlencode on my phone number string to over come the issue:

$phone = urlencode( $phone );

Answer 3

pass the data to this function to get JSON encoding with + and 0 preceded data staying as a string. I am using double encoding and str_replace to get over the issue.

public static function json_encode($data){
    $numeric = json_encode($data, JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES | JSON_NUMERIC_CHECK);
    $nonnumeric = json_encode($data, JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES);
    preg_match_all("/\"[0\+]+(\d+)\"/",$nonnumeric, $vars);
    foreach($vars[0] as $k => $v){
        $numeric = preg_replace("/\:\s*{$vars[1][$k]},/",": {$v},",$numeric);
    }
    return $numeric;
}

Answer 4

Instead of typecasting it to a string do something like this:

$output = array(
    'is_bool' => 1,
    'total_amount' => '431.65',
    'phone_number' => '"0272561313"' // add quotations
);

echo '<pre>';
echo json_encode($output,JSON_NUMERIC_CHECK | JSON_UNESCAPED_SLASHES | JSON_PRETTY_PRINT);

It'l keep the trailing zero:

{
    "is_bool": 1,
    "total_amount": 431.65,
    "phone_number": "\"0272561313\""
}

Decode:

$test = json_encode($output,JSON_NUMERIC_CHECK | JSON_UNESCAPED_SLASHES | JSON_PRETTY_PRINT);
$test = json_decode($test, true);
print_r($test);

Output:

Array
(
    [is_bool] => 1
    [total_amount] => 431.65
    [phone_number] => "0272561313"
)

Answer 5

You no need to use

JSON_NUMERIC_CHECK

Instead use attribute-casting

https://laravel.com/docs/5.1/eloquent-mutators#attribute-casting

    class SomeModel extends Model
    {
        protected $casts = [
            'field_name' => 'array',
 'status' => 'boolean'
        ];
    }

Answer 6

works for me :

// $DATAS -> datas returned by the server
$DATAS = array(
    array('tel' => '0606060606'), 
    array('tel' => '0707070707') 
);

foreach($DATAS as $k => $v){

    $tel = " ".$v['tel']." ";  // ADD WHITE SPACE
    $DATAS[$k]['tel'] = $tel;
}

echo json_encode($DATAS, JSON_NUMERIC_CHECK);

// output : [{"tel":" 0606060606 "},{"tel":" 0707070707 "}]

Maybe define css white space or trim datas in the json encoded for obtain the perfect parsed number
