title: PHP: 'salt' option to password_hash is deprecated
body: <p>I'm using password hashing for a registration. I need to create a Salt manually and following is the code I have used:</p>
  
  <pre><code>$options = [
      'cost' =&gt; 11,
      'salt' =&gt; mcrypt_create_iv(22, MCRYPT_DEV_URANDOM)
  ];
  $password = password_hash(
      $this-&gt;input-&gt;post("confirm_password"),
      PASSWORD_BCRYPT,
      $options
  );
  </code></pre>
  
  <p>When I run this code it gives me an error saying:</p>
  
  <blockquote>
    <p>password_hash(): Use of the 'salt' option to password_hash is deprecated"</p>
  </blockquote>
  
  <p>Any solution for this?</p>
