Php mysql query charset - php

Question

I have problem with query charset for mysql bd in php script.
I'm placing GET parameter inside select query and it work good for all Latin characters, but with Cyrillic characters it returns me empty table. If I place some value with Cyrillic in query instead of GET parameter, query works as I want. Likewise, I get result query inside php-Admin and it works.
All Cyrillic characters in result shows me correct.
I've checked everything: php-file is utf8, GET parameter value is utf8, mysql_client_encoding() returns me utf8.
I've tried all I found - nothing helps me.
header('Content-type:text/html; charset=utf-8');
mysql_set_charset('utf8', $link);
mysql_query("SET NAMES utf8", $link);
mysql_query("SET CHARACTER SET 'utf8'", $link);
mysql_query("SET SESSION collation_connection = 'utf8_general_ci'", $link);
mysql_query("SET character_set_results = 'utf8', character_set_client = 'utf8', character_set_connection = 'utf8', character_set_database = 'utf8', character_set_server = 'utf8'", $link);
All of this DOESN'T HELP.
Here is my php script.
<?php
$link = mysql_connect('localhost', 'r96036lg_searche', 'Jh1ZT4]^');
//mysql_set_charset('utf8', $link);
//mysql_query("SET NAMES utf8", $link);
//mysql_query("SET CHARACTER SET 'utf8'", $link);
//mysql_query("SET SESSION collation_connection = 'utf8_general_ci'", $link);
mysql_query("SET character_set_results = 'utf8', character_set_client = 'utf8', character_set_connection = 'utf8', character_set_database = 'utf8', character_set_server = 'utf8'", $link);
//echo mysql_client_encoding($link);
mysql_select_db('r96036lg_searche', $link);
//mysqli::set_charset('utf8');
$query = "select id, name, typeid from MainObjects where used = 1";
if(isset($_GET['name']) && !empty($_GET['name'])) {
//$name = mb_convert_encoding($_GET['name'], "UTF-8", "win1251");
$name = $_GET['name'];
//echo mb_detect_encoding($name, "auto", false);
//$name = iconv(mb_detect_encoding($name, "auto", false), "UTF-8", $name);
//echo $name;
$query .= " and typeid = 1 and (name like '%".$name.
"%' or id in (select parentid from MainObjects where name like '%"
.$name."%' and used = 1))";
}
//echo $query;
$result = mysql_query($query, $link);
if(!$result) echo mysql_error();
else {
$out = "[";
while($row = mysql_fetch_row($result)) {
... //here is myoutput
}
$out .= "]";
echo $out;
}
?>

This is how you should do it. It will not solve the caracter encoding thing, but it will help with the reste. (And perhaps even solve your problem, because it might just be related to not escaping the values).
$query = "select id, name, typeid from MainObjects where used = 1";
if(isset($_GET['name']) && !empty($_GET['name'])) {
$name = mysql_real_escape_string($_GET['name']);
$query .= " and typeid = 1 and (name like '%".$name.
"%' or id in (select parentid from MainObjects where name like '%"
.$name."%' and used = 1))";
}
//echo $query;
$result = mysql_query($query, $link);
I this does not help there is a character coding mismatch somewhere. There are three points:
GET data: did you try to encode the url like example.com/index.php?name=%d0%ba (cyrillic small letter ka)
communication with server. If you did really try all you said, there should not be an error
data in the tables: Does the collation of the table really correspond to its content. What I might suspect is that there is a mismatch. If the data is in UTF-8, but the table isn't, mysql will try to convert the data from one character set into another, and as a result it will not much.
