PHPExcel - How can i read the Excel sheet row by row - php

Question

How can i read Excel worksheet row by row using PHPExcel? I have a sheet contains more than 100000 rows, but i want to read only 500 rows.
$sheetData = $objPHPExcel->getActiveSheet();
$highestRow = $sheetData->getHighestRow();
$highestColumn = $sheetData->getHighestColumn();
$highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);
echo '<table>';
for ($row = 1; $row <= $highestRow; ++$row) {
echo '<tr>';
for ($col = 0; $col <= $highestColumnIndex; ++$col) {
echo '<td>' . $sheetData->getCellByColumnAndRow($col, $row)->getValue() . '</td>';
}
echo '</tr>';
}
echo '</table>';

Answer 1

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);
See the PHPExcel User Documentation - Reading Spreadsheet Files document in /Documentation for more details on Read Filters

Answer 2

You can load 500 rows or even setting start index by setting parameters directly to the getRowIterator function.
$path = "Your File Path HERE";
$fileObj = \PHPExcel_IOFactory::load( $path );
$sheetObj = $fileObj->getActiveSheet();
$startFrom = 50; //default value is 1
$limit = 550; //default value is null
foreach( $sheetObj->getRowIterator($startFrom, $limit) as $row ){
foreach( $row->getCellIterator() as $cell ){
$value = $cell->getCalculatedValue();
}
}

Answer 3

This loops through all rows and columns and assigns the cell value to $cellValue. If the $i is greater than 500, it breaks out the loop
$objWorksheet = $objPHPExcel->getActiveSheet();
$i = 0;
foreach ($objWorksheet->getRowIterator() as $row) {
if ($i > 500) break;
$i++;
foreach ($row->getCellIterator() as $cell) {
$cellValue = trim($cell->getCalculatedValue());
}
}

require_once "/PATH TO PHP EXCEL FOLDER/PHPExcel.php";
$inputFileName = $_FILES['FILENAME'];
$objTpl = PHPExcel_IOFactory::load('./PATH TO UPLOAD FOLDER/' . $inputFileName);
$sheetData = $objTpl->getActiveSheet()->toArray(null, true, true, true);
array_shift($sheetData);
$i=0;
$test_array = array();
foreach($sheetData as $key=>$val){
if($i < 500)
$test_array[$i] = $val;
$i++;
}
