[php] 二維碼

以ThinkPHP為例：

一、phpqrcode應用下載：http://sourceforge.net/projects/phpqrcode/files/應用程式下載：http://sourceforge.net/projects/phpqrcode/files/

應用程式下載：http://sourceforge.net/projects/phpqrcode/files/

應用程式下載：http://sourceforge.net/projects/phpqrcode/files/是Vendor目錄下

二、生成二維碼的方法：

<span><span>/* </span><span>二维码</span><span> */
</span><span>public function </span><span>qrcode</span>(<span><em>$url</em></span><span>=</span><span>'http://www.baidu.com'</span>,<span><em>$level</em></span><span>=</span><span>3</span>,<span><em>$size</em></span><span>=</span><span>4</span>){
    <span>Vendor</span>(<span>'phpqrcode.phpqrcode'</span>);
    $errorCorrectionLevel <span>=</span><span><em>intval</em></span>(<span><em>$level</em></span>) ;<span>//</span><span>容错级别
</span><span></span>$matrixPointSize <span>= </span><span><em>intval</em></span>(<span><em>$size</em></span>);<span>//</span><span>生成图片大小
</span><span></span><span>//</span><span>生成二维码图片</span><span></span><span></span>$object <span>= new </span>\QRcode();
    $object<span>-></span><span>png</span>(<span><em>$url</em></span>, <span>false</span>, $errorCorrectionLevel, $matrixPointSize, <span>2</span>);
}</span>

三、在模板中使用

<span><<span>img </span><span>src=</span><span>"__CONTROLLER__/qrcode" </span><span>alt=</span><span>"</span><span宋体'">百度一下二维码</span><span>"</span>/></span>
