title: Does strip_tags() handle embedded tags
body: <p>I'm away from a computer with PHP installed and was wondering what the result of strip_tags() would be on the following text:
  "&lt;scr&lt;h1&gt;ipt&gt;alert('oh oh')&lt;/scr&lt;/h1&gt;ipt&gt;"</p>
  
  <p>Would it return:
  "&lt;script&gt;alert('oh oh')&lt;/script&gt;" (i.e. not recognize that by removing the obvious tag it exposed a new one)
  or
  "alert('oh oh')</p>
  
  <p>I know that if it returns the first case I can just repeatedly call the function until I get out what I put in, but I'm curious.</p>
  
  <p>Thanks in advance.</p>
