Fatal error: Cannot redeclare Function() in PhP

Fatal error: Cannot redeclare count_words() (previously declared) in PhP
Solution
1. Don't declare a function inside a loop. Declare before them.

or
You should include the file (wherein that function exists) only once. So instead of

include  ("function.php");

use

include_once("function.php");

Fatal error: Cannot pass parameter by reference in PHP

Fatal error: Cannot pass parameter by reference in PHP.

$stmt->bind_param("ssss",$userid,$theme,$title,"test");

The error is with 'test' in the bind_param call.

All parameters to bind_param must be passed by reference. A string is a primitive value, and cannot be passed by reference.

You can fix this by creating a variable and passing that as a parameter instead:

$testvar="test";

$stmt->bind_param("ssss",$userid,$theme,$title,$testvar);

Enable or disable the "Powered by TinyMCE" branding.

Tinymce branding property allow you to enable or disable the "Powered by TinyMCE" branding.

tinymce.init({
  selector: 'textarea',  
  branding: false
});
