我想从具有未指定行数和指定列数的 Excel 工作表中读取数据。我只能用指定的行数来做，任何解决方案都会有很大帮助
$inputFileType = 'Excel5';
$inputFileName = './sampleData/example2.xls';
/** Define a Read Filter class implementing PHPExcel_Reader_IReadFilter */
class chunkReadFilter implements PHPExcel_Reader_IReadFilter
{
private $_startRow = 0;
private $_endRow = 0;
/** Set the list of rows that we want to read */
public function setRows($startRow, $chunkSize) {
$this->_startRow = $startRow;
$this->_endRow = $startRow + $chunkSize;
}
public function readCell($column, $row, $worksheetName = '') {
// Only read the heading row, and the configured rows
if (($row == 1) ||
($row >= $this->_startRow && $row < $this->_endRow)) {
return true;
}
return false;
}
}
/** Create a new Reader of the type defined in $inputFileType **/
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
/** Define how many rows we want to read for each "chunk" **/
$chunkSize = 2048;
/** Create a new Instance of our Read Filter **/
$chunkFilter = new chunkReadFilter();
/** Tell the Reader that we want to use the Read Filter **/
$objReader->setReadFilter($chunkFilter);
//I want to loop and get values from the excel sheet startrow< undefined number of rows
for ($startRow = 2; $startRow <= 65536; $startRow += $chunkSize) {
/** 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
}
