Title: In-depth understanding of the meaning and functional characteristics of PHP QR code live code
With the development of mobile Internet, QR code serves as a convenient information transmission Tools are widely used in various fields. In PHP development, more interesting functions can be achieved by generating QR codes and live codes. This article will introduce the meaning and functional characteristics of PHP QR code live code, and give specific code examples.
1. Meaning analysis
2. Functional features
Next, we give a simple PHP code example to generate a QR code live code containing a web link, and realize the function of the user jumping to the specified page after scanning.
<?php include 'phpqrcode/qrlib.php'; //引入QR Code库 // 生成二维码 $url = 'https://www.example.com'; // 要生成二维码的网页链接 $qrCodePath = 'qrcodes/example.png'; // 生成的二维码存储的路径 QRcode::png($url, $qrCodePath, 'L', 10, 2); //生成二维码 // 显示二维码 echo '<img src="' . $qrCodePath . '" alt="QR Code"/>'; // 用户扫描后跳转到指定页面 if(isset($_GET['scan']) && $_GET['scan'] == 'true'){ header('Location: ' . $url); exit(); } ?>
