PHP生成二维码：dcode
jopen
9年前
一个基于QR Code encoder的生成二维码的php扩展，同时实现了Discuz论坛系统里面的authcode函数，相比php版本速度更快，生成几万个二维码秒秒钟。如果使用Discuz论坛，需要有这方面性能提升的，那么该扩展时不错的选择。
依赖： php5.4+ libpng
示例代码：
DCode::encrypt($src, $key = "THIS IS SHIT", $ckeylength = 8, $expire = 0); DCode::decrypt($src, $key = "THIS IS SHIT", $ckeylength = 8); /** * DCode::qrcode($str, $version = 0, $level = QR_ECLEVEL_L, $mode = QR_MODE_KANJI, $casesensitive = 0); * @param $str; * @param $version = 0; * @param $level = QR_ECLEVEL_L; * @param $model = QR_MODE_KANJI; * @param $casesensitive = 0; * @return string */ $filecontent = DCode::qrcode("HELLO"); file_put_contents("test.png", $filecontent); /** * DCode::qrcode8bit($str, $version = 0, $level = QR_ECLEVEL_L); * @param $str; * @param $version = 0; * @param $level = QR_ECLEVEL_L; * @return string */ $filecontent = DCode::qrcode8bit("HELLO WORLD"); file_put_contents("test1.png", $filecontent); /** * DCode::qrcodedata($sizeof, $data, $version = 0, $level = QR_ECLEVEL_L); * @param $sizeof * @param $data * @param $version = 0; * @param $level = QR_ECLEVEL_L; * @return string */ $filecontent = DCode::qrcodedata(strlen("HELLO WORLD"), "HELLO WORLD"); file_put_contents("test2.png", $filecontent); dcode_encrypt($src, $key = "THIS IS SHIT", $ckeylength = 8, $expire = 0); dcode_decrypt($src, $key = "THIS IS SHIT", $ckeylength = 8); $filecontent = dcode_qrcode("HELLO"); file_put_contents("test.png", $filecontent); $filecontent = dcode_qrcode8bit("HELLO 8bit"); file_put_contents("test1.png", $filecontent); $filecontent = dcode_qrcodedata(strlen("HELLO 8bit"), "HELLO 8bit"); file_put_contents("test2.png", $filecontent);
