$export = mysql_query ($query ) 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 Record(s) Found!\n";                        
}


header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=".$today." Report ".$tbl_name.".xls");
header("Pragma: no-cache");
header("Expires: 0");
print "$header\n$data";

?>

Answer 1

Change this line: (it's the quotes) see ^ here and ^ here under the first line of code below.

header("Content-Disposition: attachment; filename=".$today." Report ".$tbl_name.".xls");
                                                           ^ here   ^ and here

to either (and by removing the quotes)

header("Content-Disposition: attachment; filename=".$today.Report.$tbl_name.".xls");

or

header("Content-Disposition: attachment; filename=".$today.'_' .Report.'_'.$tbl_name.".xls");

The last one will put an underscore between each name/word.

Edit: as per OP's comment

thanks guys, it's resolved. the problem is header("Content-type: application/octet-stream"); and that should be header("Content-Type: application/vnd.ms-excel;"); and thanks for the filename issues
