Description:
------------
If you need the function 'similar_text' to calculate the similarity in percentage between two strings, the order is important, while it must not be.

(see the Test script for more information)

---
From manual page: http://www.php.net/function.similar-text
---


Test script:
---------------
$var_1 = 'PHP IS GREAT';
$var_2 = 'WITH MYSQL';

similar_text($var_1, $var_2, $percent);

echo $percent;
// 27.272727272727

similar_text($var_2, $var_1, $percent);

echo $percent;
// 18.181818181818


Expected result:
----------------
I expect both the echo's to print :
27.272727272727

Actual result:
--------------
The first echo prints :
27.272727272727

The second :
18.181818181818
