Everybody knows phpMyAdmin can export file to Excel format but phpMyAdmin just export .csv file,not real Excel file format. If you are interest in PHP programming and need to export to the real Excel format please check it out !

Example PHP export to XLS file format.

1. Create Function for XLS

function xlsBOF() {
echo pack("ssssss", 0x809, 0x8, 0x0, 0x10, 0x0, 0x0);  
return;
}

function xlsEOF() {
echo pack("ss", 0x0A, 0x00);
return;
}

function xlsWriteNumber($Row, $Col, $Value) {
echo pack("sssss", 0x203, 14, $Row, $Col, 0x0);
echo pack("d", $Value);
return;
}

function xlsWriteLabel($Row, $Col, $Value ) {
$L = strlen($Value);
echo pack("ssssss", 0x204, 8 + $L, $Row, $Col, 0x0, $L);
echo $Value;
return;
}

2. Send Header to Browser in download format.

// Query Database
$result=mysql_db_query($dbname,"select id,prename,name,sname,grade from appdata where course='$courseid' and sec='$section'")

// Send Header
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");;
header("Content-Disposition: attachment;filename=$courseid-$sec.xls "); // แล้วนี่ก็ชื่อไฟล์
header("Content-Transfer-Encoding: binary ");

// XLS Data Cell

xlsBOF();
xlsWriteLabel(1,0,"Student Register $semester/$year");
xlsWriteLabel(2,0,"COURSENO : ");
xlsWriteLabel(2,1,"$courseid");
xlsWriteLabel(3,0,"TITLE : ");
xlsWriteLabel(3,1,"$title");
xlsWriteLabel(4,0,"SETION : ");
xlsWriteLabel(4,1,"$sec");
xlsWriteLabel(6,0,"NO");
xlsWriteLabel(6,1,"ID");
xlsWriteLabel(6,2,"Gender");
xlsWriteLabel(6,3,"Name");
xlsWriteLabel(6,4,"Lastname");
$xlsRow = 7;
while(list($id,$prename,$name,$sname,$grade)=mysql_fetch_row($result)) {
++$i;
xlsWriteNumber($xlsRow,0,"$i");
xlsWriteNumber($xlsRow,1,"$id");
xlsWriteLabel($xlsRow,2,"$prename");
xlsWriteLabel($xlsRow,3,"$name");
xlsWriteLabel($xlsRow,4,"$sname");
$xlsRow++;
}
xlsEOF();
exit();
