Solution to the garbled Chinese characters transmitted to the background in php: 1. Use "iconv('UTF-8', 'GB2312//IGNORE', $targetFile);"; 2. Use "move_uploaded_file($tempFile, $targetFile);".

What should I do if Chinese php is sent to the background with garbled characters?
Solution to the Chinese garbled problem of php file upload background storage:
php file upload background processing explanation:
After the user uploads the file ( I use uploadify2.3 for the front end. I hope to save it according to its original file name (sometimes in Chinese). Only using PHP's move_uploaded_file command will cause garbled characters (I am a Ubuntu server). You need to use icotargetFile=iconv(′UTF−8′,′GB2312//IGNORE′,targetFile) first; without IGNORE, iconv will fail to convert the character - (horizontal bar) and automatically truncate it afterwards. For example:
iconv('UTF-8', 'GB2312//IGNORE', "博客—yet"); // 输出"博客yet" iconv('UTF-8', 'GB2312//IGNORE', "博客—yet"); // 输出"博客"
So the correct storage method is:
$targetFile = iconv('UTF-8', 'GB2312//IGNORE', $targetFile); // UTF8转GB2312 move_uploaded_file($tempFile, $targetFile); // 服务器把文件暂时放在$tempFile
Because transcoding will lose characters, we need to save the new file name. In order to determine which characters are lost, I used this back and forth Conversion trick:
$targetFile = iconv('GB2312', 'UTF-8//IGNORE', $targetFile );
php file download background processing explanation:
When to use GB2312 and when to use UTF8 is important.
In addition, ob_clean() and flush() are the key to whether the downloaded file is garbled
<?php $ROOT = $_SERVER["DOCUMENT_ROOT"]; // 获取根路径 $filename = $_GET["filename"]; // GET方式拿到文件名 $filepath = $ROOT.$filename; // 文件路径UFT8版 $filepath_iconv = iconv('UTF-8', 'GB2312//IGNORE', $ROOT.$filename); // 文件路径GB2312版 if (is_file($filepath_iconv)) // 和上面一样,php的文件系统函数的输入一定要GB2312字符,否则is_file返回false { $fileinfo = pathinfo($filepath); // 返回给客户端的用UFT8 header('Content-type: application/x-'.$fileinfo['extension']); header('Content-Disposition: attachment; filename='.$fileinfo['basename']); header('Content-Length: '.filesize($filepath_iconv)); // GB2312才能访问文件 ob_clean(); // 如果不加这两句的话,下载下来的文件是乱码的 flush(); // 如果不加这两句的话,下载下来的文件是乱码的 readfile($filepath_iconv); // GB2312才能访问文件 exit(); } else { die("文件不存在或已被删除"); } ?>
The following is the file upload backend file I use with uploadify 2.3, for reference only:
<?php error_reporting(0); // 如果需要开启php警告,删除此句 if (!empty($_FILES)) { $my_articleDBtable = $_GET["my_articleDBtable"]; require_once("../../init.php"); // $tmpimgUploadDir在这个文件里 $tempFile = $_FILES['Filedata']['tmp_name']; $originalName = $_FILES['Filedata']['name']; if (empty($tempFile)) { die("抱歉,由于服务器原因,文件上传失败"); } $dateYmd = date("Ymd",strtotime("now")); $targetPath = $ROOT.$attachmentDir.$dateYmd.'/'; //存储文件夹(绝对路径) mkdir($targetPath, 0777, true); $new_dir_name = new_name($_FILES['Filedata']['name']); //将文件名md5加密,仅保留最后一个后缀 mkdir($targetPath.$new_dir_name, 0777, true); $targetFile = $targetPath.$new_dir_name.'/'.$originalName; //移动tmp文件到指定位置,并防止中文文件名乱码。(tmp文件是服务器自动生成的) move_uploaded_file($tempFile, iconv('UTF-8', 'GB2312//IGNORE', $targetFile)); $originalName = iconv('UTF-8', 'GB2312//IGNORE', $originalName); $originalName = iconv('GB2312', 'UTF-8//IGNORE', $originalName); //返回文件地址 $filename = $originalName; $href = $ROOTTOSERVER.$attachmentDir.$dateYmd.'/'.$new_dir_name.'/'.$originalName; $filename = mysql_real_escape_string($filename); $href = mysql_real_escape_string($href); mysql_query("insert into `$my_articleDBtable` (articleName, articleContent) VALUES ('$filename','$href')") or die(mysql_error()); die("success"); } function new_name($filename){ $ret = array(); $ext = pathinfo($filename); $ext = $ext['extension']; $ext = strtolower($ext); if ($ext=='doc'|| $ext=='docx') { $name = basename($filename,$ext); $name = md5($name.time()); //.'.'.$ext; return $name; } die("文件名不合法"); } ?>
