Przykłady

Przykład #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.

Przykład #2 strtr() example with two arguments

<?php
$trans 
= array("hello" => "hi""hi" => "hello");
echo 
strtr("hi all, I said hello"$trans);
?>

Powyższy przykład wyświetli:

hello all, I said hi
