将文件从XLS转换为CSV

Question

我正在尝试编写一个脚本，将所有文件xls转换为csv，但是当我尝试运行它时，我会出现此错误

  

致命错误：未捕获的异常＆＃39; PHPExcel_Reader_Exception＆＃39;有消息＆＃39;无法打开../public/mad/export_tarifs.xls进行阅读！文件不存在。＆＃39;在第443行的C：\ wamp \ www \ chaima \ speed-wear.net \ web \ batchs \ Classes \ PHPExcel \ Reader \ Excel5.php

这是我的代码：

require_once 'Classes/PHPExcel/IOFactory.php';

$inputFileType = 'Excel5';
$inputFileName = '../public/mad/test_batch_solsys.xls';

$objReader = PHPExcel_IOFactory::createReader($inputFileType);
$objPHPExcelReader = $objReader->load($inputFileName);

$loadedSheetNames = $objPHPExcelReader->getSheetNames();

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcelReader, 'CSV');

foreach($loadedSheetNames as $sheetIndex => $loadedSheetName) {
    $objWriter->setSheetIndex($sheetIndex);
    $objWriter->save($loadedSheetName.'.csv');
}
