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?
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!
