iconv function in PHP to convert encoding, such as UTF-8 to GB2312

This article introduces the iconv function in PHP to convert encoding, such as UTF-8 to GB2312. It has a certain reference value. Now I share it with you. Friends in need can refer to it

Recently, when I was working on the CCB interface, I found that the encoding UTF-8 must be converted into GB2312, so I used this iconv function to convert the encoding.

I found that if I use 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.

Let’s take a look at the usage of this function.

The simplest application, replace gb2312 with utf-8:

$zhuan=iconv("UTF-8","GB2312",$data);

During use, if you encounter some special characters, such as: "— ", "." and other characters in English names, the conversion is broken. The text after these characters cannot be converted further.

To solve this problem, you can use the following code to achieve it:

$zhuan=iconv("UTF-8","GBK",$data);

You read that right, that’s it It's simple, just don't use gb2312 and write it as GBK.

There is another method, the second parameter, add //IGNORE, ignore the error, as follows:

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

There is no specific comparison between these two methods. , I feel that the first method (GBK instead of gb2312) is better.
