1,使用composer安装phpexcel包:
composer require phpoffice/phpexcel
2,在控制器中创建方法:
(1)使用PHPexcel扩展。代码如下:
/**
* 导出excel表格(默认格式)
*
* @param array $columName 第一行的列名称
* @param array $list 二维数组
* @param string $setTitle sheet名称
* @return
* @author Tggui
*/
private function exportExcel1($columName, $list, $fileName='demo', $setTitle='Sheet1'){
vendor('phpoffice.phpexcel.Classes.PHPexcel');
vendor('phpoffice.phpexcel.Classes.PHPexcel.IOFactory');
if ( empty($columName) || empty($list) ) {
return '列名或者内容不能为空';
}
if ( count($list[0]) != count($columName) ) {
return '列名跟数据的列不一致';
}
$fileName = iconv("utf-8", "gb2312", $fileName);
//实例化PHPExcel类
$PHPExcel = new \PHPExcel();
//获得当前sheet对象
$PHPSheet = $PHPExcel -> getActiveSheet();
//定义sheet名称
$PHPSheet -> setTitle($setTitle);
//excel的列 这么多够用了吧?不够自个加 AA AB AC ……
$letter = [
'A','B','C','D','E','F','G','H','I','J','K','L','M',
'N','O','P','Q','R','S','T','U','V','W','X','Y','Z'
];
//把列名写入第1行 A1 B1 C1 ...
for ($i=0; $i < count($list[0]); $i++) {
//$letter[$i]1 = A1 B1 C1 $letter[$i] = 列1 列2 列3
$PHPSheet->setCellValue("$letter[$i]1","$columName[$i]");
}
//内容第2行开始
foreach ($list as $key => $val) {
//array_values 把一维数组的键转为0 1 2 3 ..
foreach (array_values($val) as $key2 => $val2) {
//$letter[$key2].($key+2) = A2 B2 C2 ……
$PHPSheet->setCellValue($letter[$key2].($key+2),$val2);
}
}
//生成2007版本的xlsx
$PHPWriter = \PHPExcel_IOFactory::createWriter($PHPExcel,'Excel2007');
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename='.$fileName.'.xlsx');
header('Cache-Control: max-age=0');
$PHPWriter->save("php://output");
exit;
}
(2),自定义函数,不使用PHPexcel扩展。代码如下:
/**
* 导出excel表格
*
* @param array $columName 第一行的列名称
* @param array $list 二维数组
* @param string $setTitle sheet名称
* @return
* @author Tggui
*/
public function exportExcel($columName, $data, $fileName='demo', $setTitle='Sheet1'){
$table = '';
if(!empty($columName) && is_array($columName)){
$table .= "";
foreach($columName as $key=>$value){
$table .= "{$value} ";
}
$table .= " ";
}
$table .= "";
if(!empty($data) && is_array($columName)){
foreach($data as $k=>$v){
$table .= "";
foreach($v as $vk=>$vv){
$table .= "{$vv} ";
}
$table .= " ";
}
}
$table .= "
";
//通过header头控制输出excel表格
header("Pragma: public");
header("Expires: 0");
header("Cache-Control:must-revalidate, post-check=0, pre-check=0");
header("Content-Type:application/force-download");
header("Content-Type:application/vnd.ms-execl");
header("Content-Type:application/octet-stream");
header("Content-Type:application/download");
header('Content-Disposition:attachment;filename="'.$fileName.'.xls"');
header("Content-Transfer-Encoding:binary");
echo $table;
}
}
3,创建导出测试方法:
/**
* @method 导出测试方法
*/
public function connectOrder()
{
//连接数据库获取数据
$clt_db = Db::connect('clt_db');
$data = $clt_db->name('admin')
->field('username,extension,email,tel')
->select();
//第一行的列数据
$header = array('用户名', '工号', '邮箱', '电话号码');
//调用导出方法
self::exportExcel1($header, $data, date('Y-m-d'));
}
