Why can't php display Chinese names? How to solve?

In web development, PHP is a very popular programming language. Although PHP is very convenient in many ways, if you have problems handling Chinese characters, then you may feel very confused. One of the problems is that PHP cannot handle Chinese file names correctly, which is also a problem that many people often encounter when using PHP. In this article, we will discuss why PHP cannot display Chinese names and how to solve this problem.

Why can’t PHP display Chinese names?

In PHP, filenames are often used as part of URLs or other purposes. When processing filenames, PHP uses the default character encoding to interpret the filename. The default character encoding is usually ISO-8859-1 (Latin-1) or Windows-1252. Neither encoding supports Chinese characters, so when you try to use Chinese characters as file names, PHP will get unrecognized characters.

Also, when you use a traditional file system (such as FAT32 or NTFS), there are some restrictions on file names. For example, the file name of the FAT32 file system can only contain a maximum of 8 characters for the file name and a 3-character extension. The file name length of the NTFS file system is limited to 255 characters, and the file name cannot contain some special characters, such as / \ : * ? " | etc.

How to solve PHP The problem of being unable to display Chinese names?

Now, let’s take a look at how to solve the problem of PHP being unable to display Chinese names.

1. Use UTF-8 encoding

UTF-8 is a globally accepted character encoding that supports multiple languages, including Chinese. Therefore, when you use Chinese names, it is best to set the character encoding to UTF-8. In PHP, you You can use the iconv or mbstring function to convert character encodings.

2. Use the urlencode function

The urlencode function is a way to convert a string into a URL-safe format. When you When the urlencode function is applied to a Chinese file name, the Chinese characters will be converted into the form of %XX (where XX represents a hexadecimal number), so that PHP can correctly handle Chinese characters.

3. Use rename function

The rename function is a file renaming function in PHP. When you try to rename a file, you can use the rename function to rename the file name. If you use the rename function to modify the Chinese file name, you need to convert the file name to an integer number, because the rename function cannot use Chinese characters as the file name.

4. Use URL Rewrite

URL Rewrite is a A common web development technology that allows you to convert dynamic URLs into static URLs. When you use URL Rewrite technology, you can use English characters or numbers instead of Chinese characters to avoid unrecognizable characters.

Summary

In this article, we discussed the problem that PHP cannot correctly handle Chinese file names. We found that the reason for this problem is because PHP uses a character encoding that does not support Chinese characters by default , and traditional file systems also have file name length and character restrictions. In order to solve this problem, we can use UTF-8 encoding, urlencode function, rename function or URL Rewrite technology. I hope this article can help you solve the problem that PHP cannot display Chinese Name problem.
