PHP Parse User Uploaded Excel File into MySQL DB - php

Question

Trying to allow the user to select a browsed excel file from their computer. Take that excel file and parse through it then write the data to a database. I am having trouble getting the parse to work. I know I need to use...
<form enctype="multipart/form-data" action="uploader.php" method="POST">
Choose a file to upload: <input name="uploadedfile" type="file" id="uploadedfile" /> <br />
<input type="submit" value="Upload File" />
and my only question is that when I use the $_FILES["uploadedfile"]["name"] it only gives me the filename and not the directory of the file so how can I pass this to PHPExcel Reader. Isn't this just a string of the filename and not actually a file path?
Heres what I have in my uploader.php:
<?php
include ('/PHPExcel/Classes/PHPExcel/IOFactory.php');
$filename = $_FILES["uploadedfile"]['name'];
echo $filename;
$inputFileType = PHPExcel_IOFactory::identify($filename);
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
$objPHPExcel = $objReader -> load($filename);
$sheet = $objPHPExcel->getSheet(0);
$highestRow = $sheet->getHighestRow();
$highestColumn = $sheet->getHighestColumn();
$data = array();
// Loop through each row of the worksheet in turn
for ($row = 1; $row <= $highestRow; $row++){
// Read a row of data into an array
$rowData = $sheet->rangeToArray('A' . $row . ':' . $highestColumn . $row,
NULL,
TRUE,
FALSE);
$data[] = $rowdata;
// Insert row data array into your database of choice here
}
foreach ($data as $param){
echo $param;
}
?>

Answer 1

You'll need the temporary name to either read it or move it to a place of your choosing:
print_r($_FILES);

Answer 2

Point the path directly and pass it to IOFactory:
$filename = $_FILES["uploadedfile"]['name'];
$fullFilename = PROJECT_DIR . 'upload/' . $filename;
$inputFileType = PHPExcel_IOFactory::identify($fullFilename);
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
$objPHPExcel = $objReader -> load($fullFilename);
