How to set php file encoding

php method to set file encoding: 1. Add "header("Content-Type: text/html; charset=gb2312")" to the PHP file; 2. Use the iconv method to encode.

How to set file encoding in php:

1. If you want to use gb2312 encoding, then php must output the header :header("Content-Type: text/html; charset=gb2312"), added to the static page. The encoding format of all files is ANSI. You can open it with Notepad. Save as and select the encoding as ANSI to overwrite the source file.

2. If you want to use utf-8 encoding, then php should output the header: header("Content-Type: text/html; charset=utf-8"), add the static page, and encode the encoding format of all files. is utf-8.

Recently, I need to use the iconv function to convert the captured utf-8 encoded page into gb2312. I found that only by using the iconv function to transcode the captured data, the data will be less for no reason. . I was depressed for a while, and after checking the information on the Internet, I found out that this was a bug in the iconv function. iconv will make an error when converting the character "-" to gb2312. The solution is very simple, that is, add "//IGNORE" after the encoding that needs to be converted, that is, after the second parameter of the iconv function, as follows:

iconv("UTF-8","GB2312//IGNORE",$data)

ignore means to ignore errors during conversion. If there is no ignore parameter, all strings following this character cannot be saved.
