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 ";

echo "test2
";

echo "test1 ";

echo "test2
";

echo "test1 ";

echo "test2
";

echo "test1 ";

echo "test2
";

echo "test1 ";

echo "test2
";

echo "test1 ";

echo "test2
";

?>

在 php環(huán)境運行上面的代碼，大家就可以看到瀏覽器詢問用戶是否下載excel文檔，點擊保存，硬盤上就多了一個excel的文件，使用excel打開 就會看到最終的結(jié)果，怎么樣不錯吧?！　∑鋵嵲谧稣嬲膽?yīng)用的時候，大家可以將數(shù)據(jù)從數(shù)據(jù)庫中取出，然后按照每一列數(shù)據(jù)結(jié)束后加 ,每一行數(shù)據(jù)結(jié)束后加
的 方法echo出來，在php的開頭用header("Content-type:application/vnd.ms-excel");表示輸出的是 excel文件，用header("Content-Disposition:filename=test.xls");表示輸出的文件名為 text.xls。這樣就ok了?！　∥覀兏梢孕薷膆eader讓他輸出更多格式的文件，這樣php在處理各種類型文件方面就更加方便了．

二、用PHP將mysql數(shù)據(jù)表轉(zhuǎn)換為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@#);

$title = "數(shù)據(jù)庫名:$DB_DBName,數(shù)據(jù)表:$DB_TBLName,備份日期:$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
");

$sep = " ";

for ($i = 0; $i < mysql_num_fields($result); $i++) {

echo mysql_field_name($result,$i) . " ";

}

print("
");

$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 .= " ";

print(trim($schema_insert));

print "
";

$i++;

}

return (true);

?>

三、PHP操作excel的一個例子（用COM對象生成excel）

這是對于那些只喜歡簡單處理一下excel朋友來說的（此方法只能在windows平臺上運行）<?php//定義一個excel文件

$workbook = "C:/My Documents/test.xls";

$sheet = "Sheet1";//生成一個com對象$ex

$ex = new COM("Excel.sheet") or Die ("連不上?。?！");//打開一個excel文件

$book = $ex->application->Workbooks->Open($workbook) or Die ("打不開?。?！");$sheets = $book->Worksheets($sheet);

$sheets->activate;//獲取一個單元格

$cell = $sheets->Cells(5,5);

$cell->activate;

//給該單元格賦值

$cell->value = 999;//保存為另一文件newtest.xls

$ex->Application->ActiveWorkbook->SaveAs("newtest.xls");//關(guān)掉excel，如果想看效果，則注釋掉下面兩行，由用戶手動關(guān)掉excel

$ex->Application->ActiveWorkbook->Close("False");

unset ($ex);?>

四、php生成EXCEL的東東

可以通過PHP來產(chǎn)生EXCEL檔。

----------------------------Excel Functions----------------------------

將下面的代碼存為excel.php ,然后在頁面中包括進(jìn)來然后調(diào)用1. Call xlsBOF()

2. 將一些內(nèi)容寫入到xlswritenunber() 或者 xlswritelabel()中.

3.然后調(diào)用 Call xlsEOF()也可以用 fwrite 函數(shù)直接寫到服務(wù)器上，而不是用echo 僅僅在瀏覽器上顯示。

<?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 footerfunction

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 -----

?>

<?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" );

xlsBOF();

streamxlsWriteLabel(0,0,"This is a label");

tooxlsWriteNumber(0,1,9999);

B1xlsEOF();

?>
