PhpExcel数组输出到Excel浏览器下载

经常是mysql查出二维数组，并且数组的带key也是有意义的，考虑到经常用，就打算弄个函数出来，方便以后用！

相对是规范的数组哈，具体可看下$data数组；

生成的excel第一行是对应的key；

直接上代码：

<?php

date_default_timezone_set(‘PRC‘);
header("Content-type: text/html; charset=utf-8");
include "E:/klaus/work/PHPdiscuz/plugin/phpexcel/PHPExcel.php";//引入phpexcel

$data[] = array(‘uid‘ => 1, ‘email‘ => ‘[email protected]‘, ‘password‘ => ‘asdsadasd‘, ‘password1‘ => ‘asdsadasd‘,
    ‘password2‘ => ‘asdsadasd‘);
$data[] = array(‘uid‘ => 1, ‘email‘ => ‘[email protected]‘, ‘password‘ => ‘asdsadasd‘, ‘password1‘ => ‘asdsadasd‘,
    ‘password2‘ => ‘asdsadasd‘);
$data[] = array(‘uid‘ => 1, ‘email‘ => ‘[email protected]‘, ‘password‘ => ‘asdsadasd‘, ‘password1‘ => ‘asdsadasd‘,
    ‘password2‘ => ‘asdsadasd‘);
$data[] = array(‘uid‘ => 1, ‘email‘ => ‘[email protected]‘, ‘password‘ => ‘asdsadasd‘, ‘password1‘ => ‘asdsadasd‘,
    ‘password2‘ => ‘asdsadasd‘);
$data[] = array(‘uid‘ => 1, ‘email‘ => ‘[email protected]‘, ‘password‘ => ‘asdsadasd‘, ‘password1‘ => ‘asdsadasd‘,
    ‘password2‘ => ‘asdsadasd‘);
$data[] = array(‘uid‘ => 1, ‘email‘ => ‘[email protected]‘, ‘password‘ => ‘asdsadasd‘, ‘password1‘ => ‘asdsadasd‘,
    ‘password2‘ => ‘asdsadasd‘);
$data[] = array(‘uid‘ => 1, ‘email‘ => ‘[email protected]‘, ‘password‘ => ‘asdsadasd‘, ‘password1‘ => ‘asdsadasd‘,
    ‘password2‘ => ‘asdsadasd‘);

arrToExcel($data,‘lptest‘);

function arrToExcel($data,$name)
{
    //处理数据，获取key
    $keys = array_keys($data[0]);
    $objPHPExcel = new PHPExcel();
    // 修改sheet名称
    $objPHPExcel->getActiveSheet()->setTitle($name . ‘_‘ . date(‘Ymd_His‘));
    // 读取数组
    for ($j = 1; $j <= count($data); $j++) {
        for ($k = 1; $k <= count($data[0]); $k++) {
            $colname = PHPExcel_Cell::stringFromColumnIndex($k - 1); // 从o开始
            $colname .= $j;
            if ($j == 1) {
                $value = $keys[$k - 1];
            } else {
                $key = $keys[$k - 1];
                $value = $data[$j - 1][$key];
            }
            $objPHPExcel->setActiveSheetIndex(0)
                ->setCellValue($colname, $value);
        }
    }
    //设置列宽
    $objPHPExcel->getActiveSheet()->getColumnDimension(‘C‘)->setWidth(49);

    // Set active sheet index to the first sheet, so Excel opens this as the first sheet
    $objPHPExcel->setActiveSheetIndex(0);
    // Redirect output to a client’s web browser (Excel5)
    header(‘Content-Type: application/vnd.ms-excel‘);
    header(‘Content-Disposition: attachment;filename=‘ . $name . ‘_‘ . date(‘Ymd_His‘) . ‘.xls‘);
    header(‘Cache-Control: max-age=0‘);
    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, ‘Excel5‘);
    $objWriter->save(‘php://output‘);
}

结果如图：

列数变下，行数变下：

结过如图：

对了补充下，sheet的名字也是变得哦！

第一次：

第二次：

大功告成！
