Solve the problem that file_get_contents cannot open the Chinese file name_PHP tutorial

Use file_get_contents to open a file or collect a remote server file. If Chinese characters are encountered in the file name or URL, the failed to open stream: Lnvalid argument in error will appear.

I encountered a very difficult problem today. The customer used ftp to transfer a file to the server, but it could not be recognized by the program. After checking the code, no problem was found. Finally, after replaying the process, I found that the file uploaded by the customer was named in Chinese. .So I did a little test and found that the file_get_contents function does not support Chinese file names.

The original code is as follows:

                                                                                                                        echo file_get_contents('./'.$filename);

The result will be displayed after execution:

The tragedy begins.

After that, I tried a lot of judgment methods and found out whether it was an encoding problem. I checked the file encoding and code encoding over and over again, but they all matched very well.

I checked the relevant information but couldn’t find it, so I googled and found that someone had encountered this problem, saying it was a system encoding problem, so I started transcoding the file name.

The file is encoded in utf-8, but the system defaults to gbk. So convert the file name to gbk first and then read it.

                                                                                                                       

$filename=iconv('utf-8','gb2312',$filename);

> // echo file_get_contents (mb_convert_encoding ('./ha .txt', 'gbk', 'utf-8')); (another method)

echo file_get_contents('./'.$filename);

Test results:

Read successfully.

OK, you’re done.
