The Chinese output by echo is displayed as garbled characters,

In fact, various server scripts should encounter this problem.

It is basically an encoding problem.

Generally speaking, most pages use the page character set for encoding compatibility reasons. Defined as utf-8

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

At this time, to display Chinese normally, you need to convert the encoding method, such as

echo iconv("GB2312","UTF-8",'Chinese' ; ;

Of course, the simplified Chinese page can also be simply,

Change the UTF-8 in

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

to gb2312

I encountered a strange phenomenon in practice.

A page that is displayed normally on the local server will echo out garbled characters when uploaded to the server.

I haven’t thought about this reason carefully, because through iconv If the function GB2312 and UTF-8 are changed and re-encoded, it will be normal.

But it must be APACHE, or more precisely, it is caused by the different settings of the PHP server.

Look at PHP. INI should be able to solve it.

Add echo iconv("GB2312","UTF-8",'Chinese'); orefc275860e5dc38998742a3c29321f6bIt will be more painful.

Finally, I saw that it might be a problem with the php.ini file configuration, so I opened the php.ini file and found;default.charset="UTF-8"--->default.charset="UTF-8" Remove the semicolon in front (remove the comment), restart the apache service, refresh the page, and the Chinese display will be normal.
