How to merge multiple excel files in a multiple excel sheet using PHP

Hey friends today i have again finished another complex task that i want to share with all of you. I need to combine multiple excel files in a multiple excel sheet. In my last tutorial you learn How to merge multiple excel files in single worksheet.
Here now i am going to explain how to merge multiple excel file in multiple sheet.

Requirenment :- My requirenment was i have a lots of files in a directory and i need to combine all these files data in a new excel file by adding all the excel data in seprate sheet. Lets understand this by an example. 

Suppose i have four excel file in a directory by the name of excel-1.xlsx, excel-2.xlsx, excel-3.xlsx, excel-4.xlsx. Now what i want to merge all these
file data into a single workbook by the name "merge-data.xlsx" in different sheet.

Below is my excel files folder structure. It will help you to better understand my requirenment. See this

To fulfill my requirement i am using PHPEXCEL library and i encluded these three file of PHPEXCEL. Below is my the sample code -


$filePath =  $argv[1];
$saving_name = "F:\commit-excel-merge-multiple\merge-data.xls";   //change the name and location of file.
require_once 'Classes/PHPExcel.php';
require_once 'Classes/PHPExcel/Writer/Excel2007.php';
require_once 'Classes/PHPExcel/IOFactory.php';

if ($dh = opendir($filePath)){
 $dataArray = array();
 $counter = 1;
 $file_name = array();
 $new_xl = new PHPExcel();
 while (($file = readdir($dh)) !== false) {
  $path_parts = pathinfo($file);  
  if ($path_parts['extension'] === 'xlsx') {   
   $singlefile = $path_parts["filename"]; //file name without extention
   echo "Start merging the content from file " . $singlefile .".xlsx" . PHP_EOL;
   $workbook_file = $filePath.'\\'. $file;
   $reader = PHPExcel_IOFactory::createReader('Excel2007');
   $xl = $reader->load($workbook_file);
   $firstSheet = $xl->getSheet(0);
   $workbook_name = $singlefile; 
   echo "End merging the content from file " . $singlefile . PHP_EOL;
 $writer = PHPExcel_IOFactory::createWriter($new_xl, 'Excel2007');
 // name of file, which needs to be attached during email sending
 echo "**********************************************************************". PHP_EOL;
 echo "All the contents of excel file are successfully merged in sheet." . PHP_EOL;
 echo "**********************************************************************". PHP_EOL;


Explain :

1- Go to the directory where you put your downloaded folder from command prompt. In the above example i put it into my "F" drive. So first i go into this folder


2- Then i run the "merge_excel_data_in_multiple_sheet.php" file by using below command.

F:\commit-excel-merge-multiple\merge-excel> php merge_excel_data_in_multiple_sheet.php F:\commit-excel-merge-multiple\merge-excel\files

3- Now after finish the process you will see the data is now stored of all the excel file from "files" folder into "F:\commit-excel-merge-multiple\merge-excel\merge-excel.xlsx" file.
