title: Why $_Post is discouraged when program a web app
body: <p>I read in a post related to a WordPress trouble, people in the post was discussing that <code>$_POST</code> is not recommended to be used when there is option such as <code>$this-&gt;property-&gt;post('value')</code> in the framework.</p>
  
  <p>Are there any specific reason for not using <code>$_POST</code> in the context of the best coding practice or its not an issue at all.</p>
