JSON Date Parsing

Demonstrates how to parse date/time strings from JSON.

Note: This example uses the DtOf and DateOf methods introduced in Chilkat v9.5.0.73

// First, let's create JSON containing some date/time strings.
$json->UpdateString('test.timestamp', '2018-01-30T20:35:00Z');

$json->UpdateString('test.dateStrings[1]', 'Tue, 24 Apr 2018 08:47:03 -0500');
$json->UpdateNumber('test.StartLoggingTime', '1446834998.695');

// We've built the following JSON:

// {
//   "test": {
//     "timestamp": "2018-01-30T20:35:00Z",
//     "rfc822": "Tue, 24 Apr 2018 08:47:03 -0500",
//     "dateStrings": [
//       "2018-01-30T20:35:00Z",
//       "Tue, 24 Apr 2018 08:47:03 -0500"
//     ],
//     "StartLoggingTime": 1446834998.695,
//     "Expiration": 1442877512.0,
//     "StartTime": 1518867432
//   }
// }

// Use the DateOf and DtOf methods to load Chilkat date/time objects with the date/time values.
// The CkDateTime object is primarily for loading a date/time from numerous formats, and then getting
// the date/time in various formats.  Thus, it's primarly for date/time format conversion.
// The DtObj object holds a date/time where the individual components (day, month, year, hour, minutes, etc.) are
// immediately accessible as integers.
$dateTime = new DateTime();
$dt = new DtObj();
$getAsLocal = false;

// Load the date/time at test.timestamp into the dateTime object.
$json->DateOf('test.timestamp', $dateTime);
echo $dateTime->GetAsTimestamp($getAsLocal), "\n";
echo $dateTime->GetAsUnixTime(false), "\n";
echo $dateTime->GetAsRfc822($getAsLocal), "\n";

$json->DateOf('test.rfc822', $dateTime);
echo $dateTime->GetAsTimestamp($getAsLocal), "\n";

$json->I = 0;
$json->DateOf('test.dateStrings[i]', $dateTime);

$json->DateOf('test.Expiration', $dateTime);
echo $dateTime->GetAsTimestamp($getAsLocal), "\n";

$json->DateOf('test.StartTime', $dateTime);
echo $dateTime->GetAsTimestamp($getAsLocal), "\n";

// Output so far:

//     2018-01-30T20:35:00Z
//     1517344500
//     Tue, 30 Jan 2018 20:35:00 GMT

// Now load the date/time strings into the dt object:
