CSV into MySQL using PHP - php

Question

I'm trying to import data from my students.csv file into mysql using php. The entries in the csv file is in such a way that column (student_number, fname, lname, level) will be inserted into biodata table..
I'm also uploading the student.csv file from my computer.
When I run the page I dont get anything out on the screen.
session_start();
require('includes/dbconnect.php');
require 'includes/header.inc.php';
//check for file upload
if (isset($_FILES['csv_file']) && is_uploaded_file($_FILES['csv_file']['tmp_name'])) {
//upload directory
$upload_dir = "C:\Users\DOTMAN\Documents\students.csv";
//create file name
$file_path = $upload_dir . $_FILES['csv_file']['name'];
//move uploaded file to upload dir
if (!move_uploaded_file($_FILES['csv_file']['tmp_name'], $file_path)) {
//error moving upload file
echo "Error moving file upload";
}
//open the csv file for reading
$handle = fopen($file_path, 'r');
//turn off autocommit and deletethe bio data
mysql_query("SET AUTOCOMMIT=0");
mysql_query("BEGIN");
mysql_query("TRUNCATE TABLE biodata") or die(mysql_error());
while (($data = fgetcsv($handle, 1000, ',')) !== FALSE) {
//Access field data in $data array ex.
$student_number = $data[0];
$fname = $data[1];
$lname = $data[2];
$level = $data[3];
//Use data to insert into db
$query = "INSERT INTO biodata (student_number, fname, lname, level)
VALUES ('$student_number', '$fname', '$lname', '$level')";
mysql_query($query) or die (mysql_error());
}
}

Answer 1

I'd suggest you to upload CSV-file with LOAD DATA INFILE command. This is fast method.

Answer 2

if you only need to do this once, i would consider using something like: http://csv2sql.com/

Answer 3

One immediate issue I can see is here:
$upload_dir = "C:\Users\DOTMAN\Documents\students.csv";
//create file name
$file_path = $upload_dir . $_FILES['csv_file']['name'];
You are already assigning the entire path, including the file name, to the $upload_dir variable - and then you're appending the uploaded file name again.
If you think there are errors in your code, start by adding
ini_set('display_errors', 1);
error_reporting(E_ALL);
to the beginning of your PHP code and fix any warnings/errors displayed. You can then turn off printing error messages by changing the second parameter to 0 in the first call.

Answer 4

Have u debug the $_FILES:
print_r($_FILES);
before doing any thing

Answer 5

Solution using PHP
$file = 'path/to.csv';
$lines = file($file);
$firstLine = $lines[0];
foreach ($lines as $line_num => $line) {
if($line_num==0) { continue; } //escape the header column
$arr = explode(",",$line);
$column1= $arr[0];
$column2= $arr[1];
echo $column1.$column2."<br />";
//put the mysql insert statement here
}
