if (!is_null($resource)){
//qrencode_save($resource, "./test.png");//保存文件
qrencode_output($resource);//直接输出到浏览器
}
echo qrencode_version()."\n";//查看版本号
?>
php-qrencode代码:
<?php
$t1 = microtime(true);
$qrcode_image = "/Users/kentchen/Downloads/qrencode1.png";
$content = "hello world";
$resource = qrencode_create($content, QRENCODE_QRECLEVEL_Q, QRENCODE_MODE_8);
qrencode_save($resource, $qrcode_image);
$t2 = microtime(true);
echo (($t2-$t1)*1000).':ms';
?>
