Examples
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);
?>
The above example will output:
hello all, I said hi
