PHP upload 14MB file failing

Question

I am trying to figure out why this upload script is failing.

Starting with the HTML FORM:

<form role="form" action="api/upload.php" method="post" enctype="multipart/form-data">
  <input id="file" name="file" type="file" />
  <input class="btn btn-primary" type="submit" value="Upload" />
</form>

Here is the PHP script:

<?php
if(isset($_FILES['file'])){
  $file = $_FILES['file'];
  $target_file = basename($_FILES["file"]["name"]);

  $file_name = $file['name'];
  $file_tmp = $file['tmp_name'];
  $file_size = $file['size'];
  $file_error = $file['error'];

  $file_ext = explode('.',$file_name);
  $file_ext = strtolower(end($file_ext));

  $allowed = array('txt', 'jpg', 'xlsx', 'pptx', 'docx', 'doc', 'xls', 'pdf');

  if(in_array($file_ext, $allowed)){
    if($file_error === 0){
      if($file_size <= 99600000){ // this was set to 600000
        $file_name_new = uniqid('', true) . '.' . $file_ext;
        $file_destination = '../files/' . $file_name;

        if(move_uploaded_file($file_tmp, $file_destination)){
          header("Location: ../index.php");
          die();
        }
        else{
          echo "There was a problem uploading the file";
        }
      }
      else{
        echo "The file is too large";
      }
    }
    else{
      echo "There was an error uploading the file";
    }
  }
  else{
    echo "The file type is not allowed";
  }
}
?>

Please forgive the nested IF statement. I was going off of this video on youtube: https://www.youtube.com/watch?v=PRCobMXhnyw

The code above works. I can upload the files, and when an error occurs, I get the appropriate error message.

However, I have come across a file that will not upload. It is an allowed file, a word document, that happens to be 14MB. Not sure if that's too large. But even still, files that I tried to upload that were too large wouldn't get past the file_size check, and I would get the corresponding error message.

In this case, all I get is a blank screen. I can echo 'hello' before and after the initial IF statement, but it fails right after the first IF.

Did you try looking at the code in $_FILES['file']['error'] if its not Zero then it will point you to an error message — RiggsFolly

I cannot echo anything after the first IF statement. Is there another way to check $file['error']? — John Beasley

Check your PHP upload_max_filesize secure.php.net/manual/en/ini.core.php#ini.upload-max-filesize — pr0gramista

The first TEST on any file upload shoudl be to look at $_FILES['file']['error'] See the first user contribution in the Manual Page for an example — RiggsFolly

You should simply increase the value of upload_max_filesize (by default it's 2M) in your php.ini file (its location depends on your operating system), and restart your web server.

@HoodCoderMan have you restarted your web server?
