Read .xlsx and .xls data in codeigniter - php

Question

I want to read the data of .xlsx or .xls file in codeigniter. I have read the other questions related it but nothing works. I have used phpexcel, reader but with no luck. In my project i give the option to upload excel file then i want to read the data and insert it in the database.
Now i am using phpExcel library I have wrote:
$this->load->library('excel');
$reader= PHPExcel_IOFactory::createReader('Excel2007');
$reader->setReadDataOnly(true);
$path=(FCPATH.'uploads/productfile/'.$_FILES['upload_file']['name']);
$excel=$reader->load($path);
$sheet=$excel->setActiveSheetIndex(0);
for($i=0;$i<=1000;$i++)
{
$col1= $sheet->getCellByColumnAndRow(0,$i)->getValue();
$col2= $sheet->getCellByColumnAndRow(1,$i)->getValue();
$col3= $sheet->getCellByColumnAndRow(2,$i)->getValue();
var_dump($col1);
}
but it display :
Uncaught exception 'PHPExcel_Exception' with message 'You tried to set
a sheet active by the out of bounds index: 0. The actual number of
sheets is 0 Please give me some example code.
The error
Please give me some example code:

Answer 1

Try this :
$sheet = $excel->getActiveSheet()->toArray(null,true,true,true);
This will return you an array of the current active sheet.Hope this helps.

Answer 2

This error is caused by a wrong initialization of the PHPexcel reader functionalities I suppose.
I usually do something like this to get the data from an excel:
require_once '../Classes/PHPExcel/IOFactory.php';
$filename = '../uploads/product/abc.xls';
$objPHPExcel = PHPExcel_IOFactory::load($filename);
foreach ($objPHPExcel->getWorksheetIterator() as $worksheet) {
$worksheetTitle = $worksheet->getTitle();
$highestRow = $worksheet->getHighestRow(); // e.g. 10
$highestColumn = $worksheet->getHighestColumn(); // e.g 'F'
$highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);
$nrColumns = ord($highestColumn) - 64;
$total_rows = $highestRow-1;
for ($row = 2; $row <= $highestRow; ++ $row) {
//id
$cell = $worksheet->getCellByColumnAndRow(0,$row);
$id = $cell->getValue();
if(is_null($id)){$id = '#';}
}

Answer 3

Thanks to all for your suggestion:
I got the solution :
$file_data = $this->upload->data();
$file_path = './uploads/productfile/'.$file_data['file_name'];
include 'Classes/PHPExcel/IOFactory.php';
$inputFileName = $file_path;
$objPHPExcel = PHPExcel_IOFactory::load($inputFileName);
$allDataInSheet = $objPHPExcel->getActiveSheet()->toArray(null,true,true,true);
$arrayCount = count($allDataInSheet); // Here get total count of row in that Excel sheet
for($i=2;$i<=$arrayCount;$i++)
{
'product'=$allDataInSheet[$i]["C"],
'brand'=$allDataInSheet[$i]["I"],
'standard'=$allDataInSheet[$i]["J"],
}

Answer 4

This extension of PHPExcel_IOFactory has issues with symbols like ™ Trademark, Copy Right, Degree etc.
You can't read a particular block if it contains such special characters.

Answer 5

This code segment works for me,
$this->load->library('excel');
$reader= PHPExcel_IOFactory::createReader('Excel2007');
$reader->setReadDataOnly(true);
$path= "./media/customer_exports/data-1558003506.xlsx";
$excel=$reader->load($path);
$sheet = $excel->getActiveSheet()->toArray(null,true,true,true);
$arrayCount = count($sheet);
for($i=2;$i<=$arrayCount;$i++)
{
echo $sheet[$i]["A"].$sheet[$i]["B"].$sheet[$i]["C"];
}
