PHPExcel how to use data from reader - php

Question

I'm trying to understand how to get data from cells in PHPExcel but I have no idea. I read all documentation and I made this:
<?php
include('PHPExcel/Classes/PHPExcel/Reader/Excel2007.php');
class MyReadFilter implements PHPExcel_Reader_IReadFilter
{
public function readCell($column, $row, $worksheetName = '') {
// Read title row and rows 20 - 30
if ($row == 1 || ($row >= 20 && $row <= 30)) {
return true;
}
return false;
}
}
$objReader = new PHPExcel_Reader_Excel2007();
$objReader->setReadFilter( new MyReadFilter() );
$objReader->setReadDataOnly(true);
$objPHPExcel = $objReader->load("sample_mymails222.xlsx");
print_r($objPHPExcel);
?>
print_r show very big array.
I think there is some functions to get data from cell in $objPHPExcel.
How to do it?
Thanx!

Answer 1

For anyone else who wants a more helpful answer, following the code in the example above, here is a quick snippet that will parse the active worksheet into a multi-dimensional array (this example ignores the ReadFilter that the OP created).
$data = array();
$worksheet = $objPHPExcel->getActiveSheet();
foreach ($worksheet->getRowIterator() as $row) {
$cellIterator = $row->getCellIterator();
$cellIterator->setIterateOnlyExistingCells(false);
foreach ($cellIterator as $cell) {
$data[$cell->getRow()][$cell->getColumn()] = $cell->getValue();
}
}
var_dump($data);
BTW The reason I say "more helpful answer" is that I also had a hard time figuring out the PHPExcel documentation (which consists of 6 separate documents and no real API-like reference) the first time around.
The OP says he "read all the docs", but I am guessing that, like me, he read through the file called PHPExcel User Documentation - Reading Spreadsheet Files.doc which explains how to read in a spreadsheet, but does not cover using the contents.
To find that out, you have to dig into PHPExcel developer documentation.doc and get down to part 4 (which is where I found the example above).
Yup, my fault for not being thorough, but clearly this is a recurring issue. :-)

for reading excel file you can use this
require_once('PHPExcel.php');
$input_file_type = PHPExcel_IOFactory::identify($excel_file);
$obj_reader = PHPExcel_IOFactory::createReader($input_file_type);
$obj_reader->setReadDataOnly(true);
$objPHPExcel = $obj_reader->load($excel_file);
$objWorksheet = $objPHPExcel->setActiveSheetIndex(0);
$highest_row = $objWorksheet->getHighestRow();
$highest_col = $objWorksheet->getHighestColumn();
//$highest_col_index = PHPExcel_Cell::columnIndexFromString($highest_col);
// start $row from 2, if you want to skip header
for ($counter = 2; $counter <= $highest_row; $counter++)
{
$row = $objWorksheet->rangeToArray('A'.$counter.':'.$highest_col.$counter);
$row = reset($row);
}

Please read the documentation chapter 4.5 (included in the PHPExcel download package)
