原生态的写法
原始方式:发送header,用附件的表头发送到用户浏览器表示是要下载的,然后读出数据库中的数据,一条一条的解析,写入excel格式的文件中,代码如下:
- <?php
- $DB_Server = "localhost";
- $DB_Username = "root";
- $DB_Password = "";
- $DB_DBName = "DBName";
- $DB_TBLName = "DB_TBLName";
- $savename = date("YmjHis");
- $Connect = @mysql_connect($DB_Server, $DB_Username, $DB_Password) or die("Couldn't connect.");
- mysql_query("Set Names 'gbk'");
- $file_type = "vnd.ms-excel";
- $file_ending = "xls";
- header("Content-Type: application/$file_type;charset=gbk");
- header("Content-Disposition: attachment; filename=".$savename.".$file_ending");
- header("Pragma: no-cache");
- $now_date = date("Y-m-j H:i:s");
- $title = "数据库名:$DB_DBName,数据表:$DB_TBLName,备份日期:$now_date";
- $sql = "Select * from $DB_TBLName";
- $ALT_Db = @mysql_select_db($DB_DBName, $Connect) or die("Couldn't select database");
- $result = @mysql_query($sql,$Connect) or die(mysql_error());
- echo("$titlen");
- $sep = "t";
- for ($i = 0;$i < mysql_num_fields($result);$i++)
- {
- echo mysql_field_name($result,$i) . "t";
- }
- print("n");
- $i = 0;
- while($row = mysql_fetch_row($result))
- {
- $schema_insert = "";
- for($j=0; $j<mysql_num_fields($result);$j++)
- {
- if(!isset($row[$j])) $schema_insert .= "NULL".$sep;
- elseif ($row[$j] != "") $schema_insert .= "$row[$j]".$sep;
- else $schema_insert .= "".$sep;
- }
- $schema_insert = str_replace($sep."$", "", $schema_insert);
- $schema_insert .= "t";
- print(trim($schema_insert));
- print "n"; $i++;
- }
- return (true);
- ?>
用PHPExcel库
下面是用PHPExcel实现的与上面功能相同的excel的方法。getCol为递归实现的函数,用于根据数字返回对应的列号编码。因为导出的过程中需要指出行号,列号,行号为简单的数字,而列号则为“A-Z”的组合,为了方便二维数组的导入,根据列数自动得到列号编码
使用说明:
1、将后面的代码存为excel.php,然后在页面中调用它。
2、然后调用 xlsBOF(),将一些内容写入到xlswritenunber() 或者 xlswritelabel()中,最后调用 xlsEOF()结束。
也可以用 fwrite 函数直接写到服务器上,而不是用echo 仅仅在浏览器上显示,下面是PHP代码:
- <?php
-
-
- function xlsBOF() {
- echo pack("ssssss", 0x809, 0x8, 0x0, 0x10, 0x0, 0x0);
- return;
- }
-
- function xlsEOF() {
- echo pack("ss", 0x0A, 0x00);
- return;
- }
-
- function xlsWriteNumber($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;
- }
- ?>
下面是调用代码:
- <?php
- header ("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
- header ("Last-Modified: " . gmdate("D,d M YH:i:s") . " GMT");
- header ("Cache-Control: no-cache, must-revalidate");
- header ("Pragma: no-cache");
- header ('Content-type: application/x-msexcel');
- header ("Content-Disposition: attachment; filename=EmplList.xls" );
- header ("Content-Description: PHP/INTERBASE Generated Data" );
-
-
-
- include ("excel.php");
- xlsBOF();
- xlsWriteLabel(0,0,"This is a label");
- xlsWriteNumber(0,1,9999);
- xlsEOF();
- ?>
