I'm trying to upload a file (xlsx) to mysql and I keep getting the same error when trying to submit. "127.0.0.1 is currently unable to handle this request". Any advices?

What I have tried:

<?php
	require('Classes/PHPExcel/IOFactory.php');
	
    $servername="localhost";
	$username="omri";
	$password="1234";
	$dbname="omri";
	
	if(isset($_POST['upload'])){
	
	$inputfilename= $_FILES['file']['tmp_name']	;
	$exceldata= array();
	
	$conn= mysqli_connect($servername, $username, $password, $dbname);
	
	if(!$conn){
	die("connection failed: ".mysqli_connect_error());	
	}	
	
	try{
		
	$inputfiletype= PHPExcel_IOFactory::identify($inputfilename);
	$objReader=	PHPExcel_IOFactory::createReader($inputfiletype);
	$objPHPExcel= $objReader ->load($inputfilename);	
		
	}	
		
	catch(Exception $e)
	{
		
	die('error loading file "'.pathinfo($inputfilename, PATHINFO_BASENAME).'": '.$e->getMessage());
		
	}	
	
	$sheet= $objPHPExcel->getSheet(0);	
	$highestrow= $sheet->getHighestRow();	
	$higestcolumn= $sheet->getHighestColumn();
		
	for($row=1; $row<=$highestrow; $row++)
	{
		
	$rowData= $sheet->rangeToArray('A'. $row .':'. $higestcolumn . $row, NULL, TRUE, FALSE );
	$sql= "INSERT INTO restricted (name, id, citizenship, expires) VALUES ('".$rowData[0][0]."','".$rowData[0][1]."','".$rowData[0][2]."','".$rowData[0][3]."')";
	
	if(mysql_query($conn,$sql)){
	$exceldata[]=$rowData[0];
	}
	
	else{
	echo "Error: " . $sql . "<br>" . mysql_error($conn);	
	}	
	}
		
	echo "<table border='1'>";
	foreach($exceldata as $index => $excelraw)
	{
		
	echo "<tr>";
	
	foreach($excelraw as $excelcolumn)
	{
		
	echo "<td>". $excelcolumn . "</td>";
		
	}	
		
	echo "</tr>";
		
	}	
		
	echo "</table>";	
	
	mysql_close($conn);	
	}
	?>

Check the error log file of your web server. It should contain more information.

1 solution

PHP
$sql= "INSERT INTO restricted (name, id, citizenship, expires) VALUES ('".$rowData[0][0]."','".$rowData[0][1]."','".$rowData[0][2]."','".$rowData[0][3]."')";

Not a solution to your question, but another problem you have.
Never build an SQL query by concatenating strings. Sooner or later, you will do it with user inputs, and this opens door to a vulnerability named "SQL injection", it is dangerous for your database and error prone.
A single quote in a name and your program crash. If a user input a name like "Brian O'Conner" can crash your app, it is an SQL injection vulnerability, and the crash is the least of the problems, a malicious user input and it is promoted to SQL commands with all credentials.
