行数と列数が指定されていないExcelシートから読みたいのですが。私は指定された行数でしかそれを行うことができません、どんな解決策も大いに役立ちます
$inputFileType = 'Excel5';
$inputFileName = './sampleData/example2.xls';

// Only read the heading row, and the configured rows
if (($row == 1) ||

}
}

/** Tell the Read Filter which rows we want this iteration **/
$chunkFilter->setRows($startRow,$chunkSize);
/** Load only the rows that match our filter **/
$objPHPExcel = $objReader->load($inputFileName);
// Do some processing here
