TP5中封装PHPEXCEL1.8导入数据以及图片功能

首先下载下来PHPEXCEL1.8的类库（https://github.com/PHPOffice/PHPExcel）放到项目目录下面的extend下面即可。


由于PHPEXCEL没有使用命名空间（namespace）的模式，所以在使用的只能使用全路径引入了。

// 引入PHPEXCEL类库
import('PHPExcel_IOFactory', EXTEND_PATH . "PhpExcel/PHPExcel/");
import('PHPExcel', EXTEND_PATH . "PhpExcel/");

使用到的Excel表格数据：




处理图片用到的功能函数我放到了common.php公共文件里面：

PHPEXCEL类库里面已经涵盖了下面几个函数，但对处理表格里面的图片的时候并不好用，所以就提取出来放到公共文件里面了。

// 应用公共文件
define('EXCEL_EXTENSION_2003', "xls");
define('EXCEL_EXTENSION_2007', "xlsx");

/**
* 处理Excel中图片
*
* @param string $file_name 文件名
* @param string $full_path 文件完整路径
*/
function process_excel_image($file_name, $full_path)
{
// 引入PHPEXCEL类
import('PHPExcel_IOFactory', EXTEND_PATH . "PhpExcel/PHPExcel/");
import('PHPExcel', EXTEND_PATH . "PhpExcel/");
// 判断文件版本，选择对应的解析文件
if(getExtendFileName($file_name) == EXCEL_EXTENSION_2003)
{
$reader = \PHPExcel_IOFactory::createReader('Excel5');
}
else if(getExtendFileName($file_name) == EXCEL_EXTENSION_2007)
{
$reader = new \PHPExcel_Reader_Excel2007();
}

// 解析Excel文件
// $objPHPExcel = $objReader->load(ROOT_PATH . "public/uploads/" . $file_path);
$PHPExcel = $reader->load($full_path);
$worksheet = $PHPExcel->getActiveSheet();
$imageInfo = extractImageFromWorksheet($worksheet, ROOT_PATH . "public/uploads/school/");

return $imageInfo;
}

/**
* 返回文件路径的信息
*
* @param string $file_name
* @return string
*/
function getExtendFileName($file_name) {

$extend = pathinfo($file_name);
$extend = strtolower($extend["extension"]);
return $extend;
}

/**
* worksheet中提取image
*
* @param object $worksheet
* @param string $basePath
*/
function extractImageFromWorksheet($worksheet,$basePath){

$result = array();

$imageFileName = "";

foreach ($worksheet->getDrawingCollection() as $drawing) {
$xy=$drawing->getCoordinates();
$path = $basePath;
// for xlsx
if ($drawing instanceof \PHPExcel_Worksheet_Drawing) {

$filename = $drawing->getPath();

$imageFileName = $drawing->getIndexedFilename();

// 可能是office版本的缘故，获取出来的图片文件名字
// 很容易造成文件名重复导致图片被覆盖，这里做了一下
// 处理对图片名字进行微秒的md5处理。
// process imageFileName
$tmp = explode(".", $imageFileName);
$tmp[0] = md5(microtime(true));
$tmp_fileName = implode(".", $tmp);
// process imageFileName

// $path = $path . $drawing->getIndexedFilename();
$path = $path . $tmp_fileName;

$boo = copy($filename, $path);

$result[$xy] = $path;

// for xls
} else if ($drawing instanceof \PHPExcel_Worksheet_MemoryDrawing) {

$image = $drawing->getImageResource();

$renderingFunction = $drawing->getRenderingFunction();

switch ($renderingFunction) {

case \PHPExcel_Worksheet_MemoryDrawing::RENDERING_JPEG:

$imageFileName = $drawing->getIndexedFilename();
$path = $path . $drawing->getIndexedFilename();
imagejpeg($image, $path);
break;

case \PHPExcel_Worksheet_MemoryDrawing::RENDERING_GIF:
$imageFileName = $drawing->getIndexedFilename();
$path = $path . $drawing->getIndexedFilename();
imagegif($image, $path);
break;

case \PHPExcel_Worksheet_MemoryDrawing::RENDERING_PNG:
$imageFileName = $drawing->getIndexedFilename();
$path = $path . $drawing->getIndexedFilename();
imagegif($image, $path);
break;

case \PHPExcel_Worksheet_MemoryDrawing::RENDERING_DEFAULT:
$imageFileName = $drawing->getIndexedFilename();
$path = $path . $drawing->getIndexedFilename();
imagegif($image, $path);
break;
}
$result[$xy] = $imageFileName;
}
}
return $result;
}

控制器中处理表格数据&图片并导入数据库表中：

    /**
* 批量导入老师
*
*/
public function t_bulk_add()
{
// 学校id
$s_id = session('s_id');

if ($this->request->method() == "POST") {
// 获取表单上传文件 例如上传了001.jpg
$file = request()->file('excel');
// 移动到框架应用根目录/public/uploads/ 目录下
$info = $file->validate([
'size'=>5242880,
'ext'=>'xls,xlsx,csv'
])->move(ROOT_PATH . 'public' . DS . 'uploads');

if ($info) {
$file_path = $info->getSaveName();
$file_name = $info->getFileName();

// 引入PHPEXCEL类库
import('PHPExcel_IOFactory', EXTEND_PATH . "PhpExcel/PHPExcel/");
import('PHPExcel', EXTEND_PATH . "PhpExcel/");
// 判断文件版本，选择对应的解析文件
if ('xlsx' == $info->getExtension()) {
import('PHPExcel_Reader_Excel2007', EXTEND_PATH . "PhpExcel/PHPExcel/Reader/");
$objReader = \PHPExcel_IOFactory::createReader('Excel2007');
} else {
import('PHPExcel_Reader_Excel5', EXTEND_PATH . "PhpExcel/PHPExcel/Reader/");
$objReader = \PHPExcel_IOFactory::createReader('Excel5');
}
$full_path = ROOT_PATH . "public/uploads/" . $file_path;

// 解析Excel文件
$objPHPExcel = $objReader->load($full_path);
// 读取第一个工作表（编号从0开始）
$sheet = $objPHPExcel->getSheet(0);
// 取得总行数
$highestRow = $sheet->getHighestRow();
// 取得总列数
$highestColumn = $sheet->getHighestColumn();
// 循环读取excel文件,读取一条,插入数组一条
for ($j=3;$j<=$highestRow;$j++) {
for ($k='A';$k<=$highestColumn;$k++) {

$examPaper_arr[$j][$k] = $objPHPExcel->getActiveSheet()->getCell("$k$j")->getValue();
}

$full_image_path = SITE_URL . "teacher/" . "$basename";

关于表格里面有图片导入的，会单独放到一篇文章里面
