title: Check if arrays are the same without any key=>value pairs
body: <p>I have two arrays, <code>$a = array("a", "b");</code> and <code>$b = array("b", "a");</code> </p>
  
  <p>I want to check if they are equal, I cannot use key=>value pairs as the PHP function populating a <code>.csv</code> into an array does not put it into key=>value pairs. (or at least to my understanding). I made this in a sandbox environment and I would appreciate it if it could stay that way. The code for the <code>.csv</code> import works and has been tested. </p>
  
  <p>Did a quick Google Search, only examples for key=>value arrays.</p>
  
  <p>PHP was kind enough to give some documentation on the matter : <a href="http://www.php.net/manual/en/language.operators.array.php" rel="nofollow noreferrer">PHP Documentation on Array Operators</a></p>
  
  <p>They did not work, as shown here : <a href="http://codepad.org/CggsZdpB" rel="nofollow noreferrer">DEMO</a></p>
  
  <p>Any tips will be highly appreciated.</p>
  
  <p>EDIT #1</p>
  
  <p>A Mod marked it as duplicate, I do not think it is a duplicate as the question handled <a href="https://stackoverflow.com/questions/23692628/verifying-key-value-pairs-between-arrays">here</a>, handles with key/value pairs.</p>
  
  <p>Am I wrong?</p>
