This article mainly introduces the problem that fopen in PHP cannot create files with Chinese file names. Interested friends can refer to it. I hope it will be helpful to everyone.

The chartset of the previous web page used utf-8, and the file also used utf-8. Then the problem came out when using fopen() to create a file with a Chinese file name. The file names were all garbled!

I checked a lot of documents and tried many methods but couldn't solve it. I was originally thinking of using other methods to bypass this problem, but suddenly it occurred to my mind that the default text encoding of Windows is ansi, and then I searched again and confirmed it. In order to understand this, my web page should also be ansi encoded so that the created file name will not be garbled.

Then I started to verify. I saved the webpages with ansi and removed the chartset statement. It was ok, but the content of the webpage became garbled. Later I remembered that this webpage also included other webpages, so I changed the include The webpage has also been changed to ansi to save, haha everything is ok

Programming is really a job that relies on accumulation. If I had never seen that the default encoding of Windows is ansi, then this problem will not be solved in a long time

ps：< meta content ="text/html; charset=utf-8" http -equiv ="Content-type" > This meta tag must be placed before to be effective

Later I thought of a better solution. The webpage is still encoded and saved in utf-8, but Just encode the file name parameter in fopen() separately. PHP has iconv(), a program that changes the encoding. By converting utf-8 to gb2312, you can avoid garbled Chinese file names.

<!DOCTYPE html>
<html>
<head>
<meta content="text/html; charset=UTF-8" http-equiv="Content-Type">
<title>标题：{title}</title>
</head>
<body>
<b>此新闻的内容：</b>{content}

##test.php

<?php

  //实际应用中很可能是查询数据库取内容。
  $rows = array(array("替换标题1","替换内容1"),array("替换标题2","替换内容2"));
  $filename = "tmp.htm";
  foreach($rows as $id => $val){
    $title = $val[0];
    $content = $val[1];
    $pagename = "测试".$id.".html"; 
    //对文件名的编码，避免中文文件名乱码
    $pagename = iconv("UTF-8", "GBK", $pagename); 
    
    //读取模板
    $tmpfile = fopen($filename,"r");
    $string = fread($tmpfile,filesize($filename));
    $string = str_replace("{title}",$title,$string);
    $string = str_replace("{content}",$content,$string);
    fclose($tmpfile);
    //写新文件
    $newpage = fopen($pagename,"w");
    fwrite($newpage,$string);
    fclose($newpage);
    
  }
  echo "创建成功！";
?>
