echo Display Chinese garbled problem

The PHP code is as follows:

echo "
ISBN: ". $isbn."
Title: ". $name."
Author: ". $author."
";

The data is obtained from the database and then assigned to $ISBN.
Garbled display

Add code:

echo "
 
   ";

After:


How to solve Ah??

Add: mysql_query ("Set names UTF8") before fetching data;

Add: mysql_query ("Set names UTF8") before fetching data;

Still the same.

What do you see in the phpMyAdmin?
What code does your database use?

Utf8_general_ci

Add: mysql_query ("Set names UTF8") before fetching data;

This is the code:

The above Connection database Mysql_set_charset ("GBK"); $result = mysql_query ("select * from book_list LIMIT 0, 30"); Query database while ($bookInfo = Mysql_fetch_array ($result)) {//Return query result to array   $ISBN = $bookInfo ["B_ISBN"];//Remove data from array    name = $bookInfo ["B_name"];    $author = $bookInfo ["B_author"];echo "
ISBN: ". $isbn."
Title: ". $name."
Author: ". $author."
";  Output Data}

Add: mysql_query ("Set names UTF8") before fetching data;

This is the code:

The above Connection database Mysql_set_charset ("GBK"); $result = mysql_query ("select * from book_list LIMIT 0, 30"); Query database while ($bookInfo = Mysql_fetch_array ($result)) {//Return query result to array   $ISBN = $bookInfo ["B_ISBN"];//Remove data from array    name = $bookInfo ["B_name"];    $author = $bookInfo ["B_author"];echo "
ISBN: ". $isbn."
Title: ". $name."
Author: ". $author."
";  Output Data}

Comment out
Mysql_set_charset ("GBK");
In front of ECHO, add:

echo "
 
   ";

Just fine.
Also, if you add mysql_query ("Set names UTF8"), all Chinese is garbled.

When displayed directly, the contents of the database read are normal. But the title, the author garbled.
Here you can know that your PHP file is UTF8, so add echo " ";
The title, the author, is normal.

Then the original read the contents of the database into garbled. It is certain that the contents of the database are not in UTF8 format. You can use Iconv conversions once to see the problem.

This sentence is changed to this echo "
ISBN: ". $isbn."
Title: ". Iconv (' GBK ', ' UTF-8 ', $name)."
Author: ". Iconv (' GBK ', ' UTF-8 ', $author)."
";  Output data

Why do you want to add Mysql_set_charset ("GBK");?

No wonder this is the case, so I think the database is not UTF8.

Mysql_set_charset ("GBK"); equals mysql_query ("Set names GBK"); You've turned around once and then UTF8 ...

UTF-8 encoded titles in the GBK environment will be displayed as CEN??
The data read from the database now displays normal
This is: The data read from the database is GBK encoded, this can be issued from the Utf-8 language declaration, garbled situation in turn to substantiate

According to your current situation, you need to $ISBN = Iconv (' GBK ', ' utf-8 ', $ISBN); Code conversion from GBK to Utf-8 for the data that will be read
And should have the header (' Content-type:text/html;charset=utf-8 '); The head of the language declaration

This behavior occurs because:
The database is Latin1
field is UTF8.
Insert yes the data is GBK
Because the character set is not declared when inserting data, the contents of GBK are inserted into the field as Latin1
The read-out also does not declare the character set, so the data in the field is read back as Latin1.
In fact, this is normal, the database should not change the stored data
Otherwise put in the warehouse is a car, get back into a motorcycle, that is not messy set it?

This is true for data already in the database, and transcoding is required if you do not want to give up (very troublesome)
When inserting and reading data in the future, it is important to note that the Set Names XXX directive is executed first, note: This xxx is the character set name of the current data
For example, the GBK data is inserted into the mysql_query ("Set names GBK");
mysql_query ("Set names UTF8") to retrieve the data according to Utf-8;

Praise! Reasonable Very good analysis.

First contact with PHP, need to connect to the database, and then Niang help find the code.
