获取列名时无法显示土耳其语字符

I'm trying to get column names with Turkish characters. Here is the code.

$cekelim=mysql_query("SELECT * FROM kategori");
$sayisi=mysql_num_fields($cekelim);
for($i=0;$i<$sayisi;$i++){
$listeleyelim=mysql_field_name($cekelim,$i);
echo $listeleyelim."<br>";
}

And I used these codes in the beginning of php file

mb_internal_encoding('UTF-8');
mysql_query('SET NAMES UTF8');
mysql_query("SET CHARACTER SET utf8");
mysql_query("SET COLLATION_CONNECTION = 'utf8_turkish_ci'");

And also I used

<meta http-equiv='Content-Type' content='text/HTML; charset=utf-8' />

between head tags in html.

Edit1:

Adding

header('Content-Type: text/html; charset=ISO-8859-9');

fixes ü and ö but doesn't work for only-in-Turkish characters.

Edit2:

I replaced all Turkish characters with numerical codes such as &#231 and I'm replacing all Turkish characters with numerical codes when inputting a new column. This is not the exact way I was looking for but this alternate way works fine.

Use header to modify the HTTP header:

<?php
header('Content-Type: text/html; charset=utf-8');

Or:

header('Content-Type: text/html; charset=ISO-8859-9');
