How to set encoding format in php

If you want to use gb2312 encoding, then PHP needs to output the header:

header(“Content-Type: text/html; charset=gb2312")

Static page addition (recommended learning: PHP programming from entry to proficiency)

<meta http-equiv="Content-Type" content="text/html; charset=gb2312">

The encoding format of all files is ANSI, which can be opened with Notepad, save as and select the encoding as ANSI to overwrite the source file.

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

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

Encoding of all files The format 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 unexplained. less.

This made me depressed for a long time. 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 the conversion This is an error. If there is no ignore parameter, all strings following this character cannot be saved.

In the php mvc controller or php page

echo &#39;<meta http-equiv="content-type" content="text/html; charset=utf-8">&#39;;

In the php page or html page

<meta http-equiv="content-type" content="text/html; charset=utf-8">

Use header function

In the controller or page

header("content-type:text/html; charset=utf-8");
