[英]How to read a excel file with merged cells in php?
我編寫了一個 php 腳本,它允許我讀取上傳的 excel 文件,並通過使用單元格值“樣式”和“顏色”將它們重命名為 style_color.jpg 來插入文件夾中包含的所有圖像。 該腳本工作正常,但如果我上傳包含合並單元格的 xlsx 文件,如下所示:
具有相同“樣式”的圖像不起作用。該工具只會將樣式放在第一張圖像上。 我想調用前兩個圖像:
SCJEG4_1041
SCJEG4_0049
如何讀取這些合並的單元格?
<?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, $imageContents);
}
?>
如果您可以假設您按順序讀取行,則可以獲得單元格值,如果單元格為空,則使用前一個值。 此代碼使用?:
表示如果它是空白的,請使用$stylecode
...
$stylecode = $sheet->getCell('H'.$row)->getValue() ?: $stylecode;
