这里使用PHPExcel的开源类

一个完整的实例：

require_once("../includes/function.php"); //提供了SQL注入检测函数inject_check

require_once("../class/DB.php"); //DB操作类，自己扩展一下

$db = new DB();

if($_GET['show_year']){

$_GET['show_year'] = inject_check($_GET['show_year']);

} else {

echo "";

return;

}

//查出开设预约的班级的学生名单

$sql = "select * from bishe_student,student where bishe_student.sno=student.sno ";

if($_GET['show_year'] && $_GET['show_year']!='-1'){

$lagreYear = $_GET['show_year']+1;

$sql .= " and bishe_student.time>='{$_GET['show_year']}

-01-01 00:00:00' and bishe_student.time

}

$sql .= "order by bishe_student.time asc; ";

$rs = $db->query($sql);

/**

*该PHP代码块开始为能够输出EXCEL文件作准备

*/

第一步，开头操作，包括引入类、设定文件基本属性

require_once("../Excel/Classes/PHPExcel.php");

require_once("../Excel/Classes/PHPExcel/Writer/Excel5.php");

//单元格的字母坐标

$colx = array('a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s'

,'t','u','v','w','x','y','z','aa','ab','ac','ad','ae','af','ag','ah','ai','ak','al',

'am','an','ao','ap','aq','ar','as','at','au','av','aw','ax','ay','az');

// 创建一个处理对象实例

$objExcel = new PHPExcel();

// 创建文件格式写入对象实例, uncomment

$objWriter = new PHPExcel_Writer_Excel5($objExcel);

//设置文档基本属性

$objProps = $objExcel->getProperties();

$objProps->setCreator( gbkToUtf8("计算机学院专业实践中心") );

$objProps->setLastModifiedBy( gbkToUtf8("计算机学院专业实践中心") );

$objProps->setTitle( gbkToUtf8("毕业设计预约学生表") );

$objProps->setSubject( gbkToUtf8("毕业设计预约学生表") );

$objProps->setDescription( gbkToUtf8("毕业设计预约学生表") );

$objProps->setKeywords( gbkToUtf8("毕业设计预约学生表") );

$objProps->setCategory( gbkToUtf8("毕业设计预约学生表") );

//*******

//设置当前的sheet索引，用于后续的内容操作。

//一般只有在使用多个sheet的时候才需要显示调用。

//缺省情况下，PHPExcel会自动创建第一个sheet被设置SheetIndex=0

$objExcel->setActiveSheetIndex(0);

$objActSheet = $objExcel->getActiveSheet();

//设置当前活动sheet的名称

$objActSheet->setTitle('sheet1');

//设置宽度

function setWidth($index,$width=5){

global $objActSheet;

$objActSheet->getColumnDimension(gbkToUtf8($index))->setWidth($width);

}

//宽度设置

for($i=0;$i<51;$i++){

//echo $colx[$i]."";

$ind = $colx[$i];

setWidth(gbkToUtf8("$ind"),11);

}

$objActSheet->getRowDimension(1)->setRowHeight(30);

$objActSheet->getRowDimension(2)->setRowHeight(20);

$objActSheet->getRowDimension(3)->setRowHeight(16);

//函数：设置border

}

//********************开始写入数据
