Chilkat ActiveX Downloads

ActiveX for 32-bit and 64-bit Windows

Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

<?php

// Note: Requires Chilkat v9.5.0.64 or greater.

// This requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// In the example linked here: PayPal OAuth2 Token,
// we fetched a PayPal access token and saved it to a JSON file.
// We also recorded the current date/time.
// Load this JSON file and compare the current date/time with the fetch date/time
// and the "expires_in" value to see if the token is expired.

$json = new COM("Chilkat_9_5_0.JsonObject");
$success = $json->LoadFile('qa_data/tokens/paypal.json');
if ($success != 1) {
    print 'Failed to load access key json file.' . "\n";
    exit;
}

// Get the current date/time.
$dateTime = new COM("Chilkat_9_5_0.CkDateTime");
$bLocalTime = 0;
$dtNow = $dateTime->GetAsUnixTime($bLocalTime);

// Get the access token create date/time
$dtCreate = $json->IntOf('tokenCreateTimeUtc');

// Find out how many seconds have elapsed.
$numSeconds = $dtNow - $dtCreate;

// Get the expires_in value from the JSON.
$expires_in = $json->IntOf('expires_in');

print 'token age (in seconds) = ' . $numSeconds . "\n";
print 'expires_in = ' . $expires_in . "\n";

// If the token expired, or if it will expire in 5 minutes or less,
// get another token.
if ($numSeconds < ($expires_in - 300)) {
    print 'The token is not yet expired.  No need to fetch another.' . "\n";
    exit;
}

print 'Time to fetch a new access token...' . "\n";

// Get another token..
// See the example at Get PayPal OAuth2 Token
// to get another token..
