PHP fileUpload with Pdf/Docx Instead of Image

问题:

I have an example code below working for images as user's input,

<?php $target_dir = "uploads/"; $target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]); $uploadOk = 1; $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);  if(isset($_POST["submit"])) {     $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);     if($check !== false) {         echo "File is an image - " . $check["mime"] . ".";         $uploadOk = 1;     } else {         echo "File is not an image.";         $uploadOk = 0;     } }  if (file_exists($target_file)) {     echo "Sorry, file already exists.";     $uploadOk = 0; }  if ($_FILES["fileToUpload"]["size"] > 500000) {     echo "Sorry, your file is too large.";     $uploadOk = 0; }  if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg" && $imageFileType != "gif" ) {     echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";     $uploadOk = 0; }  if ($uploadOk == 0) {     echo "Sorry, your file was not uploaded.";  } 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.";     } } ?> 

but my main intention is to upload Pdf & Docx as user's input this time instead of images.

I tried to change but couldn't succeeded. Any link or at least a description with a couple of links I can assume the rest works for me (I hoped if it's a duplicate but not asked the same way I guess).

Basically, I just changed all $imagefileType to $fileType and it works!! I just skipped the image check as shown with the comment section below. Even not sure if it is needed for pdf/doc & docx unlike image. I appreciate If anyone provide additional information I skipped or it's already fine this way @bxN5 @Ravinder Reddy.

It's just simple as is.

<?php $target_dir = "uploads/"; $target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]); $uploadOk = 1; $fileType = pathinfo($target_file,PATHINFO_EXTENSION); /* if(isset($_POST["submit"])) {     $check = getfilesize($_FILES["fileToUpload"]["tmp_name"]);     if($check !== false) {         echo "File is an image - " . $check["mime"] . ".";         $uploadOk = 1;     } else {         echo "File is not an image.";         $uploadOk = 0;     } } */ if (file_exists($target_file)) {     echo "Sorry, file already exists.";     $uploadOk = 0; } if ($_FILES["fileToUpload"]["size"] > 500000) {     echo "Sorry, your file is too large.";     $uploadOk = 0; } if($fileType != "pdf" && $fileType != "doc" && $fileType != "docx") {     echo "Sorry, only PDF, DOC & DOCX files are allowed.";     $uploadOk = 0; } if ($uploadOk == 0) {     echo "Sorry, your file was not uploaded."; } 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.";     } } ?>
