title: How to display PHP echo with JavaScript in HTML?
body: <p>I want to transfer PHP echo text into HTML through JavaScript.I've seen that it can be done with the function <code>document.getelementbyid()</code> and innerHTML but I tried and it did not work.</p>
  
  <p>This PHP Code:</p>
  
  <pre><code>&lt;?php
  $target_dir = "uploads/";
  $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; 500000) {
      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;
