推荐答案
如果您只想 读取 500行,则只需 load 使用读取过滤器读取500行:
If you only want to read 500 rows, then only load 500 rows using a read filter:
$inputFileType = 'Excel5';
$inputFileName = './sampleData/example2.xls';
/** Define a Read Filter class implementing PHPExcel_Reader_IReadFilter */
class myReadFilter 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 rows that are configured in $this->_startRow and $this->_endRow
if (($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 = 500;
/** Create a new Instance of our Read Filter **/
$chunkFilter = new myReadFilter();
/** Tell the Reader that we want to use the Read Filter that we've Instantiated **/
$objReader->setReadFilter($chunkFilter);
/** Tell the Read Filter, the limits on which rows we want to read this iteration **/
$chunkFilter->setRows(1,500);
/** Load only the rows that match our filter from $inputFileName to a PHPExcel Object **/
$objPHPExcel = $objReader->load($inputFileName);
