strtr is replacing in an unexpected way

Question

strtr is replacing in an unexpected way. Please take a look at my code.

$stringX = "Do you remember me?";

strtr($stringX, array("you" => "me", "me" => "you"));

Expected output: Do me remember you.

Actual output: Do me reyoumber you.

How do I get the expected output?

@Jeff And that takes off the whole point of replacing me and you at the same time. — jessica, Aug 24 '15 at 07:43

Try this:

$stringX = "Do you remember me?";

strtr($stringX, array("you" => "me", " me" => " you"));

Note the space before me!!!

NOTE: This will work only in this specific case and might produce unexpected output for other strings!

Well, just keep in mind that this solution is very specific and will only work with this case. As soon as another word that starts with 'me' is added, it'll have a similar problem again. – Katai Aug 24 '15 at 07:33

It wouldn't won't if remember is member, but if you do both spaces in front and back, and what if it's me? without a space? – jessica Aug 24 '15 at 07:47
