一个非常不错的 php QR Code 类库 使用类

//引入phpqucode类库
require_once "phpqrcode.php";
class Custom_QRcode extends Custom_Object {
private $qrcodePath;
public function __construct($option=array()){
$_option=array(
"basePath"=>APPLICATION_PATH."/",
"relativePath"=>"/",
"errorCorrectionLevel"=>"L",//// 纠错级别：7%L、15%M、25%Q、30%H--字碼可被修正
"matrixPointSize"=>4,//100x100--5:125--6:150.....(max10)
"margin"=>2,

);
$this->setConfig($_option);
$this->setConfig($option);
}
/*
$data 数据
$filename 保存的图片名称
$errorCorrectionLevel 错误处理级别
$matrixPointSize 每个黑点的像素
$margin 图片外围的白色边框像素
*/
public function createQRcode($data=''){
if(!$data){return false;}
$options = $this->_option;
$PNG_TEMP_DIR = $options['basePath'].$options['relativePath'].'/';
if(!is_dir($PNG_TEMP_DIR)){
mkdir($PNG_TEMP_DIR,0777,true);//php 5
}
$errorCorrectionLevel = $options['errorCorrectionLevel'];
$matrixPointSize = $options['matrixPointSize'];
$margin = $options['margin'];
$qrname = $this->getNewFileName($data);
$this->qrcodePath = $options['relativePath'].'/'.$qrname;
$filename = $PNG_TEMP_DIR.$qrname;
QRcode::png($data, $filename, $errorCorrectionLevel, $matrixPointSize, $margin);
return true;
}

/*** 设置配置选项* * @param $option* @return void*/

public function setConfig($option){
foreach($option as $key=>$val){
$this->_option[$key]=$val;
}
}
/*獲取文件名*/
public function getNewFileName($data){
$ecl = $this->_option['errorCorrectionLevel'];
$mps = $this->_option['matrixPointSize'];
$md5 = md5($data.'|'.$ecl.'|'.$mps);
$extName = '.png';
return substr($md5,8,16).rand(1000,10000).$extName;
}
//獲取圖片相對路徑;
public function getQrPicPath(){
return $this->qrcodePath;
}
}

//生成二维码用法

$qrdata = 'http://sourceforge.net/projects/phpqrcode/';//qrcode 类库下载地址

$QRcode = new Custom_QRcode(array(

"relativePath"=>"/qrcode/",

));

$QRcode->createQRcode($qrdata);

$qrcodesrc = $QRcode->getQrPicPath();
