将MYSQL日期导出为CSV

Question

我正在尝试将某些mysql记录导出到csv文件。我让用户选择日期范围，然后在这些日期之间显示屏幕上的记录。这样可行。我也可以将整个数据库导出到csv没问题，但是当我尝试根据日期导出csv文件时，它不起作用。 所以，这是我导出到csv代码：

header('Content-Disposition: attachment; filename="APGE_ELEC_2013MMDD.csv"');

    $hostname = "localhost"; //SET SERVER/HOSTNAME
    $dbusername = "ysername"; //SET DATABASE USERNAME
    $dbname = "test"; //SET DATABASE NAME
    $dbpassword = "password"; //SET DATABASE USERNAME

$dbhandle = mysql_connect($hostname, $dbusername, $dbpassword) 
  or die("Unable to connect to MySQL");

$selected = mysql_select_db($dbname,$dbhandle) 
  or die("Could not select Data Base");

$query = "SELECT * FROM v88374 WHERE ((date >= '$from') AND (date <= '$to'))";

$export = mysql_query ($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 = "\n(0) Records Found!\n";                        
}

print "$header\n$data";


exit();

现在，这是我的export.php文件。我有一个名为report.php的文件，它实际显示记录，然后调用export.php。这是代码：

<script type="text/javascript" language="javascript">
            jQuery(function() {
                jQuery( "#from" ).datepicker({
                  defaultDate: "+1w",
                  changeMonth: true,
                  numberOfMonths: 1,
                  dateFormat: "yy-mm-dd",
                  onClose: function( selectedDate ) {
                    $( "#to" ).datepicker( "option", "minDate", selectedDate );
                  }
                });
                jQuery( "#to" ).datepicker({
                  defaultDate: "+1w",
                  changeMonth: true,
                  numberOfMonths: 1,
                  dateFormat: "yy-mm-dd",
                  onClose: function( selectedDate ) {
                    jQuery( "#from" ).datepicker( "option", "maxDate", selectedDate );
                  }
                });
            });
</script>

    } 


    $sql = "SELECT * FROM v88374 WHERE date >= DATE_FORMAT('" . $from . "', '%Y/%m/%d') AND date <=  DATE_FORMAT('" . $to . "', '%Y/%m/%d')";

    //$result = mysqli_query($link, $sql, MYSQLI_USE_RESULT);
    if ($result = mysqli_query($link, $sql)) {
echo "

    echo "<form action='export.php'> <input type='submit' name='export' value= 'Export CSV'></form>";

我希望我解释得够了哈哈。非常感谢任何帮助！
