How To Upload Files into Database in PHP?

To store uploaded files to MySQL database, you can use the normal SELECT statement as shown in the modified processing_uploaded_files.php listed below:

<?php
  $con = mysql_connect("localhost", "", "");
  mysql_select_db("fyi");
  $error = $_FILES['fyicenter_logo']['error'];
  $tmp_name = $_FILES['fyicenter_logo']['tmp_name'];
  $size = $_FILES['fyicenter_logo']['size'];
  $name = $_FILES['fyicenter_logo']['name'];
  $type = $_FILES['fyicenter_logo']['type'];
  print("<pre>\n");
  if ($error == UPLOAD_ERR_OK && $size > 0) {
    $fp = fopen($tmp_name, 'r');
    $content = fread($fp, $size);
    fclose($fp);     
    $content = addslashes($content);
    $sql = "INSERT INTO fyi_files (name, type, size, content)"
      . " VALUES ('$name', '$type', $size, '$content')";
    mysql_query($sql, $con);
    print("File stored.\n");
  } else {
    print("Upload faield.\n");
  }
  print("&/pre>\n");
  mysql_close($con);
?>

Note that addslashes() is used to add backslashes to special characters that need to be protected in SQL statements.
