(PHP ActiveX) 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

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.JsonObject')
$json = new COM("Chilkat.JsonObject");
$json->EmitCompact = 0;

// First, let's create JSON containing some date/time strings.
$json->UpdateString('test.timestamp','2018-01-30T20:35:00Z');
$json->UpdateString('test.rfc822','Tue, 24 Apr 2018 08:47:03 -0500');
$json->UpdateString('test.dateStrings[0]','2018-01-30T20:35:00Z');
$json->UpdateString('test.dateStrings[1]','Tue, 24 Apr 2018 08:47:03 -0500');
$json->UpdateNumber('test.StartLoggingTime','1446834998.695');
$json->UpdateNumber('test.Expiration','1442877512.0');

// 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.
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.CkDateTime')
$dateTime = new COM("Chilkat.CkDateTime");
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.DtObj')
$dt = new COM("Chilkat.DtObj");
$getAsLocal = 0;

// Load the date/time at test.timestamp into the dateTime object.
$success = $json->DateOf('test.timestamp',$dateTime);
print $dateTime->getAsTimestamp($getAsLocal) . "\n";
print $dateTime->GetAsUnixTime(0) . "\n";
print $dateTime->getAsRfc822($getAsLocal) . "\n";

$success = $json->DateOf('test.rfc822',$dateTime);
print $dateTime->getAsTimestamp($getAsLocal) . "\n";

$json->I = 0;
$success = $json->DateOf('test.dateStrings[i]',$dateTime);
print $dateTime->getAsTimestamp($getAsLocal) . "\n";

$json->I = 1;
$success = $json->DateOf('test.dateStrings[i]',$dateTime);
print $dateTime->getAsTimestamp($getAsLocal) . "\n";

$success = $json->DateOf('test.StartLoggingTime',$dateTime);
print $dateTime->getAsTimestamp($getAsLocal) . "\n";

$success = $json->DateOf('test.Expiration',$dateTime);
print $dateTime->getAsTimestamp($getAsLocal) . "\n";

$success = $json->DateOf('test.StartTime',$dateTime);
print $dateTime->getAsTimestamp($getAsLocal) . "\n";

// Output so far:

// 	2018-01-30T20:35:00Z
