title: Cannot upload files exceeding 1MB in size - PHP webserver
body: <p>I am currently having a bit of a nightmare with a webserver I have. I have trawled just about every Stack Overflow page I can find and still no success. </p>
  
  <p>I have a webserver running locally which I would test these settings on first, and everything works but whenever I apply the same settings to my main server, no such luck.</p>
  
  <p>I have gone right back to basics just by using a simple html page and php page to process the request and this still fails with anything over 1MB. </p>
  
  <p>For reference, this is my html script:</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
      &lt;html&gt;
      &lt;body&gt;
  
      &lt;form action="test.php" method="post" enctype="multipart/form-data"&gt;
          Select image to upload:
          &lt;input type="file" name="fileToUpload" id="fileToUpload"&gt;
          &lt;input type="submit" value="Upload Image" name="submit"&gt;
      &lt;/form&gt;
  
      &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>This is my test.php page to process the request:</p>
  
  <pre><code>&lt;?php
  $target_dir = "";
  $target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
  $uploadOk = 1;
  $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
  
  // Check if image file is a actual image or fake image
  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.";
          $uploadOk = 0;
      }
  }
  // Check if file already exists
  if (file_exists($target_file)) {
      echo "Sorry, file already exists.";
      $uploadOk = 0;
  }
  // Check file size
  if ($_FILES["fileToUpload"]["size"] &gt; 8000000) { //8mb
      echo "Sorry, your file is too large.";
      $uploadOk = 0;
  }
  // Allow certain file formats
  if($imageFileType != "jpg" &amp;&amp; $imageFileType != "png" &amp;&amp; $imageFileType != "jpeg"
  &amp;&amp; $imageFileType != "gif" ) {
      echo "Sorry, only JPG, JPEG, PNG &amp; GIF files are allowed.";
      $uploadOk = 0;
  }
  // Check if $uploadOk is set to 0 by an error
  if ($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.";
      }
  }
  ?&gt;

  <p>This is just the basic php image upload script from w3 Schools - that is what this problem has reduced me to! </p>
  
  <p>What I have tried:</p>
  
  <ul>
  <li>Editing the php.ini file then restarting apache</li>
  <li>Changing the html form so that it includes enctype="multipart/form-data" within the form header</li>
  <li>Adding .htaccess to the root www/html folder where the files are</li>
  <li>changing the bit of the upload script which specifies the maximum allowed image size: </li>
  </ul>
  
  <p>The error I am getting is:</p>
  
  <pre><code>Warning: getimagesize(): Filename cannot be empty in /var/www/html/test.php on line 8
  File is not an image.Sorry, your file was not uploaded.
  </code></pre>
  
  <p>Can anyone help me out? I have also tried to look into disabling mod_security but I couldn't even find that on my apache2 server. </p>
  
  <p>Many thanks. </p>
