All thanks to Linmic and @Kaszoni Ferencz for sharing this. Nothing more then updated to PDO as mysql functions no more available.

// Author: Linmic, email: linmicya@gmail.com
// Updated By: Najm
$host = ""; // your db host (ip/dn)
$user = ""; // your db's privileged user account
$password = ""; // and it's password
$db_name = ""; // db name
$table_name = "";// table name of the selected db
$skip_column=[];// skip any column not needed in excel    
$db = new PDO("mysql:host=$host;dbname=$db_name;charset=utf8","$user","$password",[PDO::ATTR_PERSISTENT => true]);

$export = $db->query("DESCRIBE $table_name"); 
$fields = $export->fetchAll(PDO::FETCH_COLUMN);
$columns = "";
foreach($fields as $v)
{
    if(in_array($v,$skip_column)) continue;
    $columns .= ",".$v;
}

$columns = substr($columns,1);
$select = "SELECT $columns FROM `$table_name`";

$col_title="";
$data="";

for ($i = 0; $i < count($fields); $i++) {
    if(in_array($fields[$i],$skip_column)) continue;
    $col_title .= '<Cell ss:StyleID="2"><Data ss:Type="String">'.$fields[$i].'</Data></Cell>';
}
$col_title = '<Row>'.$col_title.'</Row>';
$export = $db->query($select);

while($row = $export->fetch(PDO::FETCH_NUM)) {
    $line = '';
    foreach($row as $value) {
        if ((!isset($value)) OR ($value == "")) {
            $value = '<Cell ss:StyleID="1"><Data ss:Type="String"></Data></Cell>\t';
        } else {
            $value = str_replace('"', '', $value);
            $value = '<Cell ss:StyleID="1"><Data ss:Type="String">' . $value . '</Data></Cell>\t';
        }
        $line .= $value;
    }
    $data .= trim("<Row>".$line."</Row>")."\n";
}
//echo "<textarea cols=50 rows=50>".$data."</textarea>";

$data = str_replace("\r","",$data);

header("Content-Type: application/vnd.ms-excel;");
header("Content-Disposition: attachment; filename=export.xls");
header("Pragma: no-cache");
header("Expires: 0");

$xls_header = '<?xml version="1.0" encoding="utf-8"?>

Add Export button:

<button  type="button" class="btn btn-warning btn-sm" onClick="tableToExcel('testTable', 'W3C Example Table')"   title="Export to Excel">Export</button></div><br/>

Add id to table:

<table class="table table-bordered table-hover " border="1" id="testTable" >

Add script at below of body:

<script type="text/javascript"> 
    var tableToExcel = (function() {
              var uri = 'data:application/vnd.ms-excel;base64,'
              , template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body><table>{table}</table></body></html>'
              , base64 = function(s) { return window.btoa(unescape(encodeURIComponent(s))) }
              , format = function(s, c) { return s.replace(/{(\w+)}/g, function(m, p) { return c[p]; }) }
              return function(table, name) {
                if (!table.nodeType) table = document.getElementById(table)
                  var ctx = {worksheet: name || 'Worksheet', table: table.innerHTML}
                window.location.href = uri + base64(format(template, ctx))
              }
            })()</script>

I think this is what you are looking for

You can create your own file by checking this address: http://www.programmingfacts.com/export-mysql-data-into-excelcsv-via-php/

I can't add working code in here sth is wrong =/

but make all \\t to \t and all \\n to \n

If you want to use PHP, consider the fputcsv function. But you can export from MySQL to text format without PHP. See this page on using mysqldump.

To create a .CSV file with syntax suitable for EXCEL you can use basic SQL:

SELECT * FROM mytable
INTO OUTFILE '/mytable.csv'
FIELDS ESCAPED BY '""'
TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\r\n';

See the manual here.
