我想使用 php 将 Data-matrix 库生成 QR 码图像存储到 mysql 数据库中。我正在尝试使用 jpgraph 库。请提供解决方案..

<?php
require_once('jpgraph/datamatrix/datamatrix.inc.php');

$data = '1234567890';

$shape       = DMAT_AUTO;
$encoding    = ENCODING_AUTO;
$modulewidth = 3;
$quietzone   = 10;
$color1      = 'black';
$color0      = 'white';
$colorq      = 'white';
$outputfile  = '';

// Create and set parameters for the encoder
$encoder = DatamatrixFactory::Create($shape);
$encoder->SetEncoding($encoding);

// Create the image backend (default)
$backend = DatamatrixBackendFactory::Create($encoder);

// By default the module width is 2 pixel so we increase it a bit
$backend->SetModuleWidth($modulewidth);

// Set Quiet zone
$backend->SetQuietZone($quietzone);

// Set other than default colors (one, zero, quiet zone/background)
$backend->SetColor($color1, $color0, $colorq);

// Create the barcode from the given data string and write to output file
try {
    $backend->Stroke($data,$outputfile);
} catch (Exception $e) {
    $errstr = $e->GetMessage();
    echo "Datamatrix error message: $errstr\n";
}
?>
