 New Comment:

can't repeat (tested with MySQL 4.1 and 5.0):

<?php
$connect=mysql_connect("localhost","phptest","php");

$select=mysql_select_db("test",$connect);

/* create test table */
mysql_query("DROP TABLE IF EXISTS test_35183");
mysql_query("CREATE TABLE test_35183 (a varchar(20) character set
utf8)");

/* set client connection to utf8 */
mysql_query("SET NAMES utf8");

$expected = "&#22235;&#22823;&#30342;&#31354;";

$query="insert into test1 values ('$expected')";
$result=mysql_query($query);

if (($result=mysql_query("select a from test_35183")))
{
    $row=mysql_fetch_row($result);
    printf("Expected: %s  Returned: %s\n", $expected, $row[0]);
}

mysql_query("DROP TABLE test_35183");
mysql_free_result($result);
mysql_close();
?>

Output:
Expected: &#22235;&#22823;&#30342;&#31354;  Returned:
&#22235;&#22823;&#30342;&#31354;

The problem maybe "Data truncation"  When php write to mysql
but I do not know resolve it

do the same without PHP (using the console interface of MySQL in  
gnome-terminal
-----------------------------------------------------------
drop table test1;
create table test1(id int,name char(4));
insert into test1 values(1,'皆大欢喜');
insert into test1 values(2,'四大皆空');
select * from test1;
id | name
1  | 皆大欢喜
2  | 四大皆空
-------------------------------------------
the reslut is good!

Why do I think it's a problem of PHP, not MySQL

1st. read/write by console vs. by php

by console: the result is right
by php    : the result is wrong,write four Chinese character and read
only one chinese character back,and other character lost.

2nd. read Mysql by java vs. by php (creat record by console)
by java: the result is right
by php : the result is ? at field 'name'

Try to do the same without PHP (using the console interface of MySQL)
and see if it works this way.
If it does, put the code somewhere in the Net and paste the link here,
so the Unicode data won't be corrupted by the bug system.
Also add the expected and actual results, I doubt I can guess them
myself.
And try to explain why do you think it's a problem of PHP, not MySQL or
something else (I'd be glad if you try to use something close to English
to do that).
