export Mysql table data to CSV with PHP on header without html code

I am trying to export some some data from Mysql with PHP to .CSV file

The issue is script export .CSV file but in the .CSV file before tabels there are HTML code

Here you have the script

// Get all fields names in table "mytablename" in database "pendejas".
$fields = mysql_list_fields(pendejas,$table_name);

// Count the table fields and put the value into $columns.
$columns = mysql_num_fields($fields);

// Put the name of all fields to $out.
for ($i = 0; $i < $columns; $i++) {
$l=mysql_field_name($fields, $i);
$out .= '"'.$l.'",';
}
$out .="\n";

// Add all values in the table to $out.
while ($l = mysql_fetch_array($result)) {
for ($i = 0; $i < $columns; $i++) {
$out .='"'.$l["$i"].'",';
}
$out .="\n";
}

// Open file export.csv.
$f = fopen ('export.csv','w');

// Put all values from $out to export.csv.
fputs($f, $out);
fclose($f);

header('Content-type: application/csv');
header('Content-Disposition: attachment; filename=$table_name.csv');
readfile('$table_name.csv');
?>

How can i export ONLY Mysql Table contains ?

EDIT : SOLVED !

Here you have script

<?php

$result = mysql_query("SELECT  name, time FROM $table_name");

ob_end_clean();

if ($result) {
    while ($row = mysql_fetch_array($result)) {
        $pasajeros .= $row["name"] . ";". $row["time"]. "\r\n"; //note the comma here
    }
}
$filename = "pasajeros_" . date("Y-m-d_H-i"); 
header("Content-type: application/vnd.ms-excel");
header("Content-disposition: csv" . date("Y-m-d") . ".csv");
header("Content-disposition: filename=" . $table_name . ".csv");
print $pasajeros;
exit();
