PHP生成excel(1)

先到PHPExcel官网下载PHPExcel类

把excel类包含进来，然后直接使用

<?php
require "./PHPExcel/PHPExcel.php";

//实例化excel类
$objPHPExcel = new PHPExcel();

//获得当前活动sheet的操作对象
$objSheet = $objPHPExcel->getActiveSheet();

//给当前活动sheet设置名称
$objSheet->setTitle("demo1");

//给当前sheet填充数据方法一
$objSheet->setCellValue("A1","姓名")->setCellValue("B1","分数");
$objSheet->setCellValue("A2","张三")->setCellValue("B2","50");
$objSheet->setCellValue("A3","李四")->setCellValue("B3","60");

//方法二不建议使用比较耗内存
/*$array = array(
    array('姓名','分数'),//相当于excel的列
    array('李四','100'),
    array('张三','90')
);
$objSheet->fromArray($array);//直接加载数据块*/

//按照指定格式生成excel文件
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');//生成excel 2007
$objWriter->save('myexchel.xlsx');
