Making a “real” and full translation of any language, including made up languages such as 1337, takes a lot of time. More time than any of us think it is worth, I guess. With these already strange languages such as 1337 a lack of grammar isn’t too disturbing and therefore this replace_all method works quite fine. As you can see I have compiled the complete list for you, so just copy and paste… but don’t forget to give this site credits.

<div style="clear: both;">phrase = "I hate leet speak!";
phrase = string_lower(phrase);
phrase = string_replace_all(phrase,"a","4";
phrase = string_replace_all(phrase,"b","|3";
phrase = string_replace_all(phrase,"c","(";
phrase = string_replace_all(phrase,"d","|)";
phrase = string_replace_all(phrase,"e","3";
phrase = string_replace_all(phrase,"f","|=";
phrase = string_replace_all(phrase,"g","9";
phrase = string_replace_all(phrase,"h","|-|";
phrase = string_replace_all(phrase,"i","!";
phrase = string_replace_all(phrase,"j","_|";
phrase = string_replace_all(phrase,"k","|{";
phrase = string_replace_all(phrase,"l","1";
phrase = string_replace_all(phrase,"m","//";
phrase = string_replace_all(phrase,"n","//";
phrase = string_replace_all(phrase,"o","0";
phrase = string_replace_all(phrase,"p","Þ";
phrase = string_replace_all(phrase,"q","";
phrase = string_replace_all(phrase,"r","|2";
phrase = string_replace_all(phrase,"s","5";
phrase = string_replace_all(phrase,"t","7";
phrase = string_replace_all(phrase,"u","|_|";
phrase = string_replace_all(phrase,"v","/";
phrase = string_replace_all(phrase,"w","|/|";
phrase = string_replace_all(phrase,"x","><";
phrase = string_replace_all(phrase,"y","¥";
phrase = string_replace_all(phrase,"z","2";
</div>
…Now phrase = ! |-|473 1337 5Þ34|{!
