// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

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

$scmd = new CkScMinidriver();

// Reader names (smart card readers or USB tokens) can be discovered
// via List Readers or Find Smart Cards
$readerName = 'Alcor Micro USB Smart Card Reader 0';
$success = $scmd->AcquireContext($readerName);
if ($success == false) {
    print $scmd->lastErrorText() . "\n";
    exit;
}

// If we are successful, the name of the currently inserted smart card is available:
$cardName = $scmd->cardName();
print 'Card name: ' . $cardName . "\n";

// Also, the ATR of the inserted card is available (you will likely not need the ATR).
print 'ATR: ' . $scmd->atr() . "\n";

// Also, the maximum number of key containers is readily available:
print 'Max number of key containers = ' . $scmd->get_MaxContainers() . "\n";

// Delete the context when finished with the card.
$success = $scmd->DeleteContext();
if ($success == false) {
    print $scmd->lastErrorText() . "\n";
}

// Sample output:

// Card name: IDPrime MD T=0
// ATR: 3B7F96000080318065B0855956FB120FFE829000
// Max number of key containers = 20
