strtr() - string

If given three arguments, this function returns a copy of
   str where all occurrences of each (single-byte)
   character in from have been translated to the
   corresponding character in to, i.e., every
   occurrence of $from[$n] has been replaced with
   $to[$n], where $n is a valid
   offset in both arguments.

Parameters : 
 str - The string being translated. 
 from - The string being translated to to. 
 to - The string replacing from. 
 replace_pairs - The replace_pairs parameter may be used instead of 
       to and from, in which case it's an
       array in the form array('from' => 'to', ...). 

Syntax

string strtr
    ( string $str
   , string $from
   , string $to
   )
