What to do if php fread() is garbled ?

In php, files are read directly through the fread function. If the file content encounters Chinese characters, the problem will be garbled. How to solve this problem?

It may be that the encoding of the output page is inconsistent with the encoding of the file being read.

Solution:

Try transcoding the content after reading it out

iconv('gbk', 'utf-8', $data)

iconv

(PHP 4 >= 4.0.5, PHP 5, PHP 7, PHP 8)

iconv — Convert a string according to the required character encoding

Description

iconv(string $in_charset, string $out_charset, string $str): string

Convert the string str from in_charset to out_charset.

Parameters

in_charset

Input character set.

out_charset

Output character set.

If you add the string //TRANSLIT after out_charset, the transliteration function will be enabled. This means that when a character cannot be represented by the target character set, it can be approximated by one or more similar characters. If you add the string //IGNORE, characters that cannot be expressed in the target character set will be silently discarded. Otherwise, an E_NOTICE is caused and false is returned.

Warning

//TRANSLIT 运行细节高度依赖于系统的 iconv() 实现（参见 ICONV_IMPL）。 据悉，某些系统上的实现会直接忽略 //TRANSLIT，所以转换也有可能失败，out_charset 会是不合格的。

str

The string to convert.

Return value

Returns the converted string, or returns false on failure.
