title: Do you have an example where the third parameter is necessary for array_search to work properly in PHP?
body: <pre><code>mixed array_search  ( mixed $needle  , array $haystack  [, bool $strict  ] )
  
  If the third parameter strict  is set to TRUE  then the array_search() function will also check the types of the needle  in the haystack . 
  </code></pre>
  
  <p>I don't see what it means,maybe an example can help?</p>
