Demonstrates how to call ensureBuffer to ensure efficiency (high-performance) when appending large amounts of data to a CkByteData.

use chilkat;


$data = new chilkat::CkByteData();

#  Pre-allocate 20MB (if necessary) for the appends to follow.
#  This will prevent re-occuring (internal) buffer reallocation,
#  and dramatically improves performance.
$data->ensureBuffer(20000000);

for ($i = 0; $i <= 1000000; $i++) {
    $data->appendStr("1234567890ABCDEF");
}

$sz = $data->getSize();
print $sz . "\r\n";
