<?php
set_time_limit(0);
   // Edit upload location here
   $destination_path = getcwd().DIRECTORY_SEPARATOR."MyXls/";

   $result = 0;
   $f = $_FILES['myfile']['name'];
   $target_path = $destination_path . basename( $_FILES['myfile']['name']);

   if(@move_uploaded_file($_FILES['myfile']['tmp_name'], $target_path)) {
	  
	$strPath = realpath(basename(getenv($_SERVER["SCRIPT_NAME"]))); // C:/AppServ/www/myphp
	$OpenFile = "MyXls/'$f'";
	//*** Create Exce.Application ***//
	$xlApp = new COM("Excel.Application", NULL, CP_UTF8) or Die ("Did not instantiate Excel");
	$xlBook = $xlApp->Workbooks->Open($destination_path."/".$target_path);
	//$xlBook = $xlApp->Workbooks->Open(realpath($OpenFile));

	$xlSheet1 = $xlBook->Worksheets(1);	
	$count = $xlSheet1->UsedRange->Rows->Count();
	include "conex.php";
	$PlanDate = $xlSheet1->Cells->Item(1,1);
	$lp = strlen($PlanDate);
	$planD = substr($PlanDate, 62, $lp); 
	$newplanD = ereg_replace('[[:space:]]+', ' ', trim($planD));
	   for($i=5;$i<=150;$i++){
		if(trim($xlSheet1->Cells->Item($i,2)) != "")
		{
			$weight = number_format( $xlSheet1->Cells->Item($i,13) , 2 );

			
			$strSQL = "";
			$strSQL .= "INSERT INTO plantable ";
