strtr — Translate certain characters
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.
Returns the translated string.
If replace_pairs contains a key which is an empty string (""), FALSE will be returned.
Example #1 strtr() example
$addr = strtr($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
$trans = array("hello" => "hi", "hi" => "hello");
echo strtr("hi all, I said hello", $trans);
The above example will output:
hello all, I said hi
