在开发一个商城网站的时候，客户需要一个导出报表的功能，我使用phpexcel来实现这个功能。
下载phpexcel_1.8.0_doc.zip ，，将解压后的文件夹里的classes上传到网站的根目录下，classes目录内的内容如下：
导出文件excel.php
require_once dirname(__file__).'/classes/phpexcel.php';//引入phpexcel.....此处略去从数据库获取数据的过程，$a为需要导出的数组......$numarr = 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','aj','ak','al','am','an','ao','ap','aq','ar','as','at','au','av','aw','ax','ay','az');// create new phpexcel object$objphpexcel = new phpexcel();$arr = array('订单号','下单时间','城市','地区', '客户名称', '收货人', '联系电话', '收货地址', 'erp客户名称', '物流系统客户名称', '活动项目', '品牌', '型号', '颜色', '物流系统型号', '订货量', '单价', '代收货款', '红包', '价保返利', '运费', '实收金额', '付款方式', '订单来源', '上游厂商', '是否在仓', '快递面单号', '订单状态', '确认时间', '末次状态确认时间', '描述', '对应业务', '对应客服', '商家留言', '下单摘要', '业务员', '联系方式');// 输出标题echo date('h:i:s') , add some data , eol;//设置换行$objphpexcel->getactivesheet()->getstyle('h')->getalignment()->setwraptext(true);$objphpexcel->getactivesheet()->getstyle('y')->getalignment()->setwraptext(true);//设置相应列的宽度$objphpexcel->setactivesheetindex(0)->getcolumndimension('a')->setwidth(15);$objphpexcel->setactivesheetindex(0)->getcolumndimension('b')->setwidth(20);$objphpexcel->setactivesheetindex(0)->getcolumndimension('g')->setwidth(15);$objphpexcel->setactivesheetindex(0)->getcolumndimension('h')->setwidth(40);$objphpexcel->setactivesheetindex(0)->getcolumndimension('i')->setwidth(15);$objphpexcel->setactivesheetindex(0)->getcolumndimension('j')->setwidth(15);//输出第一行$objphpexcel->setactivesheetindex(0)->setcellvalue('a1', $arr[0]) ->setcellvalue('b1', $arr[1]) ->setcellvalue('c1', $arr[2]) ->setcellvalue('d1', $arr[3]) ->setcellvalue('e1', $arr[4]) ->setcellvalue('f1', $arr[5]) ->setcellvalue('g1', $arr[6]) ->setcellvalue('h1', $arr[7]) ->setcellvalue('i1', $arr[8]) ->setcellvalue('j1', $arr[9])->setcellvalue('k1', $arr[10])->setcellvalue('l1', $arr[11]);//输出内容for($i=0;$isetactivesheetindex(0) ->setcellvalue($numarr[0].($i+2), $a[$i]['order_sn']) ->setcellvalue($numarr[1].($i+2), $a[$i]['add_time']) ->setcellvalue($numarr[2].($i+2), $a[$i]['city']) ->setcellvalue($numarr[3].($i+2), $a[$i]['region_name']) ->setcellvalue($numarr[4].($i+2), $a[$i]['company']) ->setcellvalue($numarr[5].($i+2), $a[$i]['consignee']) ->setcellvalue($numarr[6].($i+2), $a[$i]['mobile']) ->setcellvalue($numarr[7].($i+2), $a[$i]['address']) ->setcellvalue($numarr[8].($i+2), '') ->setcellvalue($numarr[9].($i+2), '') ->setcellvalue($numarr[10].($i+2), '') ->setcellvalue($numarr[11].($i+2), $a[$i]['brand_name']);}// rename worksheetecho date('h:i:s') , rename worksheet , eol;$dirname = date(ymd);//目录名$filename = date(ymdhis);//文件名$objphpexcel->getactivesheet()->settitle($filename);// set active sheet index to the first sheet, so excel opens this as the first sheet$objphpexcel->setactivesheetindex(0);// save excel 2007 fileecho date('h:i:s') , write to excel2007 format , eol;$callstarttime = microtime(true);if(!opendir('../excel/'.$dirname)){ mkdir('../excel/'.$dirname);}$objwriter = phpexcel_iofactory::createwriter($objphpexcel, 'excel2007');$objwriter->save('../excel/'.$dirname.'/'.$filename.'.xlsx');$end = getcurrenttime();$spend = $end-$begin;if ($spend > 30){ echo ''; exit;}header('location:'.$_server['http_host'].'/excel/'.$dirname.'/'.$filename.'.xlsx');
