PHPExcel Codeigniter : Fatal error: Uncaught exception 'PHPExcel_Reader_Exception' - php

Question

I am working on a project in which i need to import data form a excel(.xlsx) fileinto a table in database. I already write code for a controller upload.php
$this->load->library('excel');
ini_set('memory_limit', '-1');
$objReader = PHPExcel_IOFactory::createReader('Excel2007');
$objReader->setReadDataOnly(true);
$path = $_SERVER['DOCUMENT_ROOT'] . '/bitcoinreports/uploads/data.xlsx';
$objPHPExcel=$objReader->load($path);
$objWorksheet = $objPHPExcel->setActiveSheetIndex(0);
//loop from first data until last data
for($i=2; $i<=77; $i++){
$name = $objWorksheet->getCellByColumnAndRow(0,$i)->getValue();
$email = $objWorksheet->getCellByColumnAndRow(1,$i)->getValue();
$phone = $objWorksheet->getCellByColumnAndRow(2,$i)->getValue();
$details = $objWorksheet->getCellByColumnAndRow(3,$i)->getValue();
$location = $objWorksheet->getCellByColumnAndRow(4,$i)->getValue();
$data_user = array(
"name" => $name,
"email" => $email ,
"phone" => $phone ,
"details" => $details ,
"location" => $location ,
);
$this->dashboard_model->add_data($data_user);
}
Whenever i call this controller i got the following error
Fatal error: Uncaught exception 'PHPExcel_Reader_Exception' with message 'Could not open C:/xampp/htdocs/bitcoinreports/uploads/data.xlsx for reading! File does not exist.' in C:\xampp\htdocs\bitcoinreports\application\third_party\PHPExcel\Reader\Excel2007.php:347

How to solve this problem ?

Answer 1

Before opening the file, check if it exists, AND is readable for the process that runs PHP (xampp in this case. Not sure how the user is named in xampp, maybe apache).
http://php.net/manual/en/function.is-readable.php
is_readable — Tells whether a file exists and is readable
So replace this:
$objPHPExcel=$objReader->load($path);
with
if (is_readable($path)){
$objPHPExcel=$objReader->load($path);
} else {
// handle problem, for example
echo "cannot read $path";
exit;
}
