TalkPHP - Export table to sql

Good day to you,
I have added an options to my db production site which is to back up the table into csv file, see code below.

Now I would like to be able to export to sql file, how would I do it without using phpMyadmin , I would like to use a function like the following.

PHP Code:


		
			
<?php
$host = 'localhost';
$user = '....';
$pass = '....';
$db = '....';
$table = $_GET[table];
$file = 'export';

$link = mysql_connect($host, $user, $pass) or die("Can not connect." . mysql_error());
mysql_select_db($db) or die("Can not connect.");

$result = mysql_query("SHOW COLUMNS FROM ".$table."");
$i = 0;
if (mysql_num_rows($result) > 0) {
while ($row = mysql_fetch_assoc($result)) {
$csv_output .= $row['Field']."; ";
$i++;
}
}
$csv_output .= "\n";

$values = mysql_query("SELECT * FROM ".$table."");
while ($rowr = mysql_fetch_row($values)) {
for ($j=0;$j<$i;$j++) {
$csv_output .= $rowr[$j]."; ";
}
$csv_output .= "\n";
}

$filename = "Backup__".$table."__".date("Y-m-d_H-i",time());
header("Content-type: application/vnd.ms-excel");
header("Content-disposition: csv" . date("Y-m-d") . ".csv");
header( "Content-disposition: filename=".$filename.".csv");
print $csv_output;
exit;
echo "Exporting...";
?>

Thanks!
