如何在php中读取具有合并单元格的Excel文件？

如何解决如何在php中读取具有合并单元格的Excel文件？

我编写了一个PHP脚本，该脚本允许我读取上载的excel文件，并通过将其重命名为“ style”和“ color”单元格值以具有style_color.jpg来插入文件夹中包含的所有图像。该脚本可以正常工作，但是如果我上传包含如下所示合并单元格的xlsx文件：

具有相同“样式”的图像不起作用。该工具会将样式放在第一张图像上。我希望将前两个图像称为：

SCJEG4_1041
SCJEG4_0049

如何阅读这些合并的单元格？

<?PHP

//uploaded xlsx file recovery
$xlsx="C:/wamp64/www/Extract_pictures_Excel/xlsx_files/".date('Y_m_d H-i-s')."_images.xlsx";
move_uploaded_file($_FILES["mon_fichier"]["tmp_name"],$xlsx);

require_once 'PHPExcel/Classes/PHPExcel/IOFactory.PHP';
$objPHPExcel = PHPExcel_IOFactory::load($xlsx);

//Unique name folder for the pictures
$dirname = uniqid();
mkdir("C:/wamp64/www/Extract_pictures_Excel/pictures_folders/$dirname/");

//reading the xlsx file
$sheet = $objPHPExcel->getActiveSheet();
foreach ($sheet->getDrawingCollection() as $drawing ) {
    
    if ($drawing instanceof PHPExcel_Worksheet_MemoryDrawing) {
        ob_start();
        call_user_func(
            $drawing->getRenderingFunction(),$drawing->getimageResource()
        );
        $imageContents = ob_get_contents();
        ob_end_clean();
        switch ($drawing->getMimeType()) {
            case PHPExcel_Worksheet_MemoryDrawing::MIMETYPE_PNG :
                $extension = 'png'; break;
            case PHPExcel_Worksheet_MemoryDrawing::MIMETYPE_GIF:
                $extension = 'gif'; break;
            case PHPExcel_Worksheet_MemoryDrawing::MIMETYPE_JPEG :
                $extension = 'jpg'; break;
        }
    } else {
        $zipReader = fopen($drawing->getPath(),'r');
        $imageContents = '';
        while (!feof($zipReader)) {
            $imageContents .= fread($zipReader,1024);
        }
        fclose($zipReader);
        $extension = $drawing->getExtension();
        $chemin = "C:/wamp64/www/Extract_pictures_Excel/pictures_folders/$dirname/";
    }    
    
    //retrieving cell values for the images name
    $row = (int) substr($drawing->getCoordinates(),1);        
    $stylecode = $sheet->getCell('H'.$row)->getValue();
    $colorcode = $sheet->getCell('E'.$row)->getValue();
    $finalname = $stylecode.'_'.$colorcode;
    $myFileName = $chemin.$finalname.'.'.$extension;
    file_put_contents($myFileName,$imageContents); 
}

?>

解决方法

如果可以假定您按顺序读取行，则可以获取单元格的值；如果单元格为空，请使用先前的值。这段代码使用?:表示是否为空白，请使用$stylecode ...

$stylecode = $sheet->getCell('H'.$row)->getValue() ?: $stylecode;
