php mysql export to excel multiple sheets

Question

I have several queries need to be exported to one file with one sheet (with query name) per query. Here is code for one;

$select = "SELECT * from data";

$export = mysql_query ( $select ) or die ( "Sql error : " . mysql_error( ) );

$fields = mysql_num_fields ( $export );

for ( $i = 0; $i < $fields; $i++ )
{
    $header .= mysql_field_name( $export , $i ) . "\t";
}

while( $row = mysql_fetch_row( $export ) )
{
    $line = '';
    foreach( $row as $value )
    {                                            
        if ( ( !isset( $value ) ) || ( $value == "" ) )
        {
            $value = "\t";
        }
        else
        {
            $value = str_replace( '"' , '""' , $value );
            $value = '"' . $value . '"' . "\t";
        }
        $line .= $value;
    }
    $data .= trim( $line ) . "\n";
}
$data = str_replace( "\r" , "" , $data );

if ( $data == "" )
{
    $data = "\nNo Data!\n";                        
}

header("Content-type: application/vnd.ms-excel");
header("Content-Disposition: attachment; filename=Test.xls");
header("Pragma: no-cache");
header("Expires: 0");
print "$header\n$data"; 
exit();

How can i use this code with multiple queries to multiple sheets?

Suggest that you look at some of the PHP libraries that can actually write real Excel BIFF or OfficeOpenXML files rather than simply using a csv renamed as .xls

In addition to my own PHPExcel, you can find a list of alternatives here
