php生成二维码时出现中文乱码的解决方法_php技巧
本文实例讲述了php生成二维码时出现中文乱码的解决方法。分享给大家供大家参考。具体分析如下:
最近做了个扫描二维码得到vcard的项目,遇到一个问题,有一部分生成完的二维码,用android系统手机扫描后得到的vcard中的中文姓名是乱码,经过比对发现,这部分vcard中ORG这个类型没有内容,随即判断没内容就加上一个固定的字符串,这样乱码的问题得以解决.
php生成二维码的几种方式
1.google开放api,代码如下:
generateQRfromGoogle($urlToEncode);
function generateQRfromGoogle($chl,$widhtHeight ='150',$EC_level='L',$margin='0')
{
$url = urlencode($url);
echo '';
}
2.php类库PHP QR Code
地址:http://phpqrcode.sourceforge.net/
下载:http://sourceforge.net/projects/phpqrcode/
用例,代码如下:
# 创建一个二维码文件
# 生成图片到浏览器
3.libqrencode
地址:http://fukuchi.org/works/qrencode/index.en.html
4.QRcode Perl CGI & PHP scripts
地址:http://www.swetake.com/qr/qr_cgi.html
第2种方法中在二维码中间加上logo,修改phpqrcode.php中的QRimage类里的png方法,代码如下:
{
$image = self::image($frame, $pixelPerPoint, $outerFrame);
if($mergePic) {
$im = imagecreatefrompng($mergePic);
$w = imagesx($im);
$h = imagesy($im);
ImageAlphaBlending($image, true);
ImageAlphaBlending($im, true);
$qrw = (imagesx($image)-$w)/2;
$qrh = (imagesy($image)-$h)/2;
imagecopy($image, $im, $qrw, $qrh, 0, 0, $w, $h);
imagedestroy($im);
}
if ($filename === false) {
Header("Content-type: image/png");
ImagePng($image);
} else {
ImagePng($image, $filename);
if($saveandprint===TRUE){
header("Content-type: image/png");
ImagePng($image);
}
}
ImageDestroy($image);
}
希望本文所述对大家的PHP程序设计有所帮助。

In MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.
