Description
string 
strtr ( string str, string from, string to )
string 
strtr ( string str, array replace_pairs )
     This function returns a copy of str,
     translating all occurrences of each character in
     from to the corresponding character in
     to.
    
     If from and to are
     different lengths, the extra characters in the longer of the two
     are ignored.
     
| Example 1. strtr() example | 
<?php$addr = strtr($addr, "äåö", "aao");
 ?>

     strtr() may be called with only two
     arguments. If called with two arguments it behaves in a new way:
     from then has to be an array that contains
     string -> string pairs that will be replaced in the source
     string. strtr() will always look for the
     longest possible match first and will *NOT* try to replace stuff
     that it has already worked on.
    
| Example 2. strtr() example with two arguments | 
<?php$trans = array("hello" => "hi", "hi" => "hello");
 echo strtr("hi all, I said hello", $trans);
 ?>

Note: 
      This optional to and 
      from parameters were added in PHP 4.0.0
