一、php,不用COM,生成excel文件
<? header("Content-type:application/vnd.ms-excel"); header("Content-Disposition:filename=test.xls"); echo "test1\t"; echo "test2\t\n"; echo "test1\t"; echo "test2\t\n"; echo "test1\t"; echo "test2\t\n"; echo "test1\t"; echo "test2\t\n"; echo "test1\t"; echo "test2\t\n"; echo "test1\t"; echo "test2\t\n"; ?>
在php环境运行上面的代码,大家就可以看到浏览器询问用户是否下载excel文档,点击保存,硬盘上就多了一个excel的文件,使用excel打开就会看到最终的结果,怎么样不错吧。
其实在做真正的应用的时候,大家可以将数据从数据库中取出,然后按照每一列数据结束后加\t,每一行数据结束后加\n的方法echo出来,在php的开头用header("Content-type:application/vnd.ms-excel");表示输出的是excel文件,用header("Content-Disposition:filename=test.xls");表示输出的文件名为text.xls。这样就ok了。
我们更可以修改header让他输出更多格式的文件,这样php在处理各种类型文件方面就更加方便了.
二、用PHP将mysql数据表转换为excel文件格式
<?php $DB_Server = "localhost"; $DB_Username = "mydowns"; $DB_Password = ""; $DB_DBName = "mydowns"; $DB_TBLName = "user"; $Connect = @mysql_connect($DB_Server, $DB_Username, $DB_Password) or die("Couldn@#t connect."); $Db = @mysql_select_db($DB_DBName, $Connect) or die("Couldn@#t select database."); $file_type = "vnd.ms-excel"; $file_ending = "xls"; header("Content-Type: application/$file_type"); header("Content-Disposition: attachment; filename=mydowns.$file_ending"); header("Pragma: no-cache"); header("Expires: 0"); $now_date = date(@#Y-m-d H:i@#); $title = "数据库名:$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,$Connect) or die(mysql_error()); echo("$title\n"); $sep = "\t"; for ($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); ?>
三、PHP操作excel的一个例子(用COM对象生成excel)
这是对于那些只喜欢简单处理一下excel朋友来说的
<?php //定义一个excel文件 $workbook = "C:/My Documents/test.xls"; $sheet = "Sheet1"; //生成一个com对象$ex $ex = new COM("Excel.sheet") or Die ("连不上!!!"); //打开一个excel文件 $book = $ex->application->Workbooks->Open($workbook) or Die ("打不开!!!"); $sheets = $book->Worksheets($sheet); $sheets->activate; //获取一个单元格 $cell = $sheets->Cells(5,5); $cell->activate; //给该单元格赋值 $cell->value = 999; //保存为另一文件newtest.xls $ex->Application->ActiveWorkbook->SaveAs("newtest.xls"); //关掉excel,如果想看效果,则注释掉下面两行,由用户手动关掉excel $ex->Application->ActiveWorkbook->Close("False"); unset ($ex); ?>
四、php生成EXCEL的东东
可以通过PHP来产生EXCEL档。
----------------------------
Excel Functions
----------------------------
将下面的代码存为excel.php ,然后在页面中包括进来
然后调用
1. Call xlsBOF()
2. 将一些内容写入到xlswritenunber() 或者 xlswritelabel()中.
3.然后调用 Call xlsEOF()
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。
<?php // ----- begin of function library ----- // Excel begin of file header function xlsBOF() { echo pack("ssssss", 0x809, 0x8, 0x0, 0x10, 0x0, 0x0); return; } // Excel end of file footer function xlsEOF() { echo pack("ss", 0x0A, 0x00); return; } // Function to write a Number (double) into Row, Col function xlsWriteNumber($Row, $Col, $Value) { echo pack("sssss", 0x203, 14, $Row, $Col, 0x0); echo pack("d", $Value); return; } // Function to write a label (text) into Row, Col function xlsWriteLabel($Row, $Col, $Value ) { $L = strlen($Value); echo pack("ssssss", 0x204, 8 + $L, $Row, $Col, 0x0, $L); echo $Value; return; } // ----- end of function library ----- ?> // // To display the contents directly in a MIME compatible browser // add the following lines on TOP of your PHP file: <?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" ); // // the next lines demonstrate the generation of the Excel stream // xlsBOF(); // begin Excel stream xlsWriteLabel(0,0,"This is a label"); // write a label in A1, use for dates too xlsWriteNumber(0,1,9999); // write a number B1 xlsEOF(); // close the stream ?>
