Upload DOC or PDF using PHP

To upload a DOC or PDF file using PHP, you will need to use the move_uploaded_file function. This function moves an uploaded file to a new location.

Here is an example of how you can use this function to upload a DOC or PDF file:

<?php

$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);

if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
  echo "The file " . basename($_FILES["fileToUpload"]["name"]) . " has been uploaded.";
} else {
  echo "Sorry, there was an error uploading your file.";
}

?>

This example assumes that you have a form on your webpage with an input field named fileToUpload. When the form is submitted, the file will be uploaded to the uploads directory on your server.

You can also use the $_FILES array to check if the file is a DOC or PDF file before uploading it. Here is an example of how you can do this:

<?php

$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;

// Check if file is a DOC or PDF file
$fileType = strtolower(pathinfo($target_file, PATHINFO_EXTENSION));
if ($fileType != "doc" && $fileType != "pdf") {
  echo "Sorry, only DOC and PDF files are allowed.";
  $uploadOk = 0;
}

if ($uploadOk == 0) {
  echo "Sorry, your file was not uploaded.";
  // if everything is ok, try to upload file
} else {
  if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
    echo "The file " . basename($_FILES["fileToUpload"]["name"]) . " has been uploaded.";
  } else {
    echo "Sorry, there was an error uploading your file.";
  }
}

?>

This example checks the file extension of the uploaded file and only allows the file to be uploaded if it is a DOC or PDF file. If the file is not a DOC or PDF file, an error message is displayed.
