首先下载PHPEXCEL 下载地址:https://github.com/PHPOffice/PHPExcel
一、生成Excel
<?php
require "PHPExcel-1.8.0/Classes/PHPExcel.php";//引入PHPExcel加载文件
$obj_PHPExcel = new PHPExcel();//实例化PHPExcel类 等同于新建一个Excel表格
$obj_Sheet = $obj_PHPExcel->getActiveSheet(); //获得当前活动sheet的活动对象
//$obj_PHPExcel->createSheet();//可以循环创建多个sheet,在建立多个sheet时使用
//$obj_PHPExcel->setActiveSheetIndex(0);//设置为活动sheet 从0开始
//$obj_Sheet = $obj_PHPExcel->getActiveSheet(); //获得当前活动sheet的活动对象
$obj_Sheet->setTitle('s1');//设置当前活动Sheet名称
//1.逐个单元格进行填充
//$obj_Sheet->setCellValue("A1", "姓名")->setCellValue("B1", "分数");//填充数据
//$obj_Sheet->setCellValue("A2", "张三")->setCellValue("B2", "50");//填充数据
//$obj_PHPExcel->getActiveSheet()->mergeCells('A1:F1');//合并单元格A1:F1(起始坐标,结束坐标)
//$obj_PHPExcel->getActiveSheet()->unmergeCells('A1:F1');// 拆分单元格
$obj_Sheet->getDefaultStyle()->getAlignment() //设置居中显示
->setVertical(\PHPExcel_Style_Alignment::VERTICAL_CENTER)//垂直居中
->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);//水平居中
//2.传入数组的方式填充
//$obj_Sheet->fromArray([
// ['标题1','标题2'], //第一个数组为第一行,数组的第一个元素为第一列
// ['1','2'],
// ['3','4'],
// ['5','6'],
// ['7','8'],
// ['9','0'],
//]);
$result = [
['id' => 'ID号', 'name' => '用户', 'pwd' => '密码', 'addr' => '地址'],
['id' => '2w5s2525dw88ee8wq87', 'name' => 'test01', 'pwd' => '123456', 'addr' => '广州'],
['id' => 'd15as6ds1d6as11das6', 'name' => 'test02', 'pwd' => '123456', 'addr' => '广州'],
['id' => 'eq4wqw564e56wq46e4w', 'name' => 'test03', 'pwd' => '123456', 'addr' => '广州'],
['id' => 'dasx4zx56c4x564c56a', 'name' => 'test04', 'pwd' => '123456', 'addr' => '广州'],
['id' => 'we6qw456eq4w56e4q56', 'name' => 'test05', 'pwd' => '123456', 'addr' => '广州'],
['id' => 'd4as56d1456q4545454', 'name' => 'test06', 'pwd' => '123456', 'addr' => '广州'],
['id' => 'e4qw64e6qw46eq46447', 'name' => 'test07', 'pwd' => '123456', 'addr' => '广州'],
['id' => '6e4q6we8qw7e89wq78e', 'name' => 'test08', 'pwd' => '123456', 'addr' => '广州'],
['id' => 'e897e9qw87e98qw798e', 'name' => 'test09', 'pwd' => '123456', 'addr' => '广州'],
];
$obj_Sheet->fromArray($result);//填充数组
$obj_Writer = PHPExcel_IOFactory::createWriter($obj_PHPExcel, 'Excel2007');//创建工厂对象
//操作1 保存文件
//$obj_Writer->save('demo.xlsx');//执行保存文件
//操作2 输出浏览器
browser_export('demo', false);
$obj_Writer->save('php://output');
//输出到浏览器 判断文件类型
function browser_export($filename, $type = 'Excel5'){
// Redirect output to a client’s web browser (Excel5)
if ($type == 'Excel5') {
$ext = '.xls';
header('Content-Type: application/vnd.ms-excel');//输出excel03文件
}
else {
$ext = '.xlsx';
header('Content-Type: application/vnd.openxmlformats- officedocument.spreadsheetml.sheet');//输出excel07文件
}
header('Content-Disposition: attachment;filename="'.$filename.$ext.'"');//输出文件的名称
header('Cache-Control: max-age=0');//禁止缓存
}

二、导入Excel
<?php
header('Content-type:text/html;charset=UTF-8');
require "PHPExcel-1.8.0/Classes/PHPExcel/IOFactory.php";//引入读取excel类文件
$filename = __DIR__.'/demo.xlsx';//需要导入的excel路径
//1.部分加载
$file_type = PHPExcel_IOFactory::identify($filename);//读取文件类型
$obj_reader = PHPExcel_IOFactory::createReader($file_type);//获取文件操作对象
$obj_reader->setLoadSheetsOnly('s1');//只读取sheet的名称 多个可以用数组array(sheet1,sheet2...)
$obj_PHPExcel = $obj_reader->load($filename);//加载文件
//2.全部加载
//$obj_PHPExcel = PHPExcel_IOFactory::load($filename); //加载文件
//$sheet_count = $obj_PHPExcel->getSheetCount(); //获取文件sheet数量
/*1.全部读取
for ($i=0; $i < $sheet_count; $i++) {
$data = $obj_PHPExcel->getSheet($i)->toArray();//读取每个sheet的数据放入数组中
var_dump($data);
}
*/
/*2.逐行读取*/
foreach ($obj_PHPExcel->getWorksheetIterator() as $sheet) { //循环读取sheet
foreach ($sheet->getRowIterator() as $row) { //逐行处理
//去除头部,只显示数据
if ($row->getRowIndex() < 2 ){
continue;
}
foreach ($row->getCellIterator() as $cell) { //逐列获取
$data = $cell->getValue();//读取单元格数据
echo $data.' ';
}
echo "<br>";
}
echo "<br>";

三、前端下载excel
1.生成excel文件 使用html5 download属性
<a href="http://localhost/PHPExcel/demo.xlsx" download="demo.xlsx">Download file</a>
2.执行PHP脚本 直接输出到浏览器
<a href="http://localhost/PHPExcel/import.php" >Download file</a>

PHP直接生成excel文件
header("Content-Type: application/vnd.ms-excel");
header("Content-Disposition:filename={$file_name}.xls");
header("Pragma: no-cache");
header("Expires: 0");
//此种方法直接输出html表格 因为Excel的兼容性可以打开,但不是真正的excel表格
echo '<html xmlns:x="urn:schemas-microsoft-com:office:excel">';
echo '<meta http-equiv="Content-type" content="text/html;charset=utf-8" /> ';
echo $excel_content;//直接输出html的表格代码
echo '</html>';
}
