今天接到了一个从Excel内读取图片的需求,在网上查找了一些资料,基本实现了自己的需求,不过由于查到的一些代码比较久远,里面一些库方法已经被移除不存在了,所以不能直接移植到自己的项目里,需要稍加改动一下。
这里介绍一下分别使用phpspreadsheet和PHPExcel扩展库来实现读取Excel内图片的功能:
PHPSpreadsheet
首先安装phpspreadsheet,由于线上服务器PHP版本是PHP5.6,所以需要安装兼容PHP5.6的版本,这里安装1.8.2版本
composer require phpoffice/phpspreadsheet=1.8.2
然后就可以在项目里使用了
use PhpOffice\\PhpSpreadsheet\\Cell\\Coordinate;
use PhpOffice\\PhpSpreadsheet\\IOFactory;
$imageFilePath = \'./uploads/imgs/\'; //图片本地存储的路径
if (!file_exists($imageFilePath)) { //如果目录不存在则递归创建
mkdir($imageFilePath, 0777, true);
}
try {
$inputFileName = \'./files/1.xlsx\'; //包含图片的Excel文件
$objRead = IOFactory::createReader(\'Xlsx\');
$objSpreadsheet = $objRead->load($inputFileName);
$objWorksheet = $objSpreadsheet->getSheet(0);
$data = $objWorksheet->toArray();
foreach ($objWorksheet->getDrawingCollection() as $drawing) {
list($startColumn, $startRow) = Coordinate::coordinateFromString($drawing->getCoordinates());
$imageFileName = $drawing->getCoordinates() . mt_rand(1000, 9999);
switch ($drawing->getExtension()) {
case \'jpg\':
case \'jpeg\':
$imageFileName .= \'.jpg\';
$source = imagecreatefromjpeg($drawing->getPath());
imagejpeg($source, $imageFilePath . $imageFileName);
break;
case \'gif\':
$imageFileName .= \'.gif\';
$source = imagecreatefromgif($drawing->getPath());
imagegif($source, $imageFilePath . $imageFileName);
break;
case \'png\':
$imageFileName .= \'.png\';
$source = imagecreatefrompng($drawing->getPath());
imagepng($source, $imageFilePath, $imageFileName);
break;
}
$startColumn = ABC2decimal($startColumn);
$data[$startRow-1][$startColumn] = $imageFilePath . $imageFileName;
}
dump($data);die();
} catch (\\Exception $e) {
throw $e;
}
public function ABC2decimal($abc)
{
$ten = 0;
$len = strlen($abc);
for($i=1;$i<=$len;$i++){
$char = substr($abc,0-$i,1);//反向获取单个字符
$int = ord($char);
$ten += ($int-65)*pow(26,$i-1);
}
return $ten;
}
可以看到,图片被读取并存到了本地服务器中
PHPExcel
PHPExcel实现从Excel文件里读取内容的方法和phpspreadsheet几乎一样,毕竟phpspreadsheet就是在PHPExcel基础上写的,不过PHPExcel由于已经被废弃了,所以建议优先使用phpspreadsheet,如果原来项目里一直使用了PHPExcel也可以继续使用PHPExcel的方法
use PHPExcel_IOFactory;
use PHPExcel_Cell;
try {
$inputFileName = \'./files/1.xlsx\';
$inputFileType = PHPExcel_IOFactory::identify($inputFileName);
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
$objPHPExcel = $objReader->load($inputFileName);
} catch (\\Exception $e) {
die(\'加载文件发生错误:"\'.pathinfo($inputFileName,PATHINFO_BASENAME).\'": \'.$e->getMessage());
}
$sheet = $objPHPExcel->getSheet(0);
$data = $sheet->toArray(); //该方法读取不到图片,图片需单独处理
$imageFilePath = \'./uploads/imgs/\'; //图片本地存储的路径
if (!file_exists($imageFilePath)) {
mkdir($imageFilePath, 0777, true);
}
//处理图片
foreach ($sheet->getDrawingCollection() as $img) {
list($startColumn, $startRow) = PHPExcel_Cell::coordinateFromString($img->getCoordinates()); //获取图片所在行和列
$imageFileName = $img->getCoordinates() . mt_rand(1000, 9999);
switch($img->getExtension()) {
case \'jpg\':
case \'jpeg\':
$imageFileName .= \'.jpeg\';
$source = imagecreatefromjpeg($img->getPath());
imagejpeg($source, $imageFilePath.$imageFileName);
break;
case \'gif\':
$imageFileName .= \'.gif\';
$source = imagecreatefromgif($img->getPath());
imagejpeg($source, $imageFilePath.$imageFileName);
break;
case \'png\':
$imageFileName .= \'.png\';
$source = imagecreatefrompng($img->getPath());
imagejpeg($source, $imageFilePath.$imageFileName);
break;
}
$startColumn = ABC2decimal($startColumn);
$data[$startRow-1][$startColumn] = $imageFilePath . $imageFileName;
}
var_dump($data);
public function ABC2decimal($abc)
{
$ten = 0;
$len = strlen($abc);
for($i=1;$i<=$len;$i++){
$char = substr($abc,0-$i,1);//反向获取单个字符
$int = ord($char);
$ten += ($int-65)*pow(26,$i-1);
}
return $ten;
}
