Delete new lines at the end of the string

I have a string from a textarea and I want to delete all new lines after the last word or character?

For example I have this string from the textbox

 $str = "Hi, my name is Blah

 x)

 ";

I need to remove new lines after the last word or character which is x)

So the results should be like this

 $result = "Hi my name is Blah

 x)";

I have tried str_replace, explode, rtrim but I cannot think of the algorithm.

Note: I don't want to remove ALL new lines. Just the one after the last word or character. TIA

What's wrong with rtrim()? If you omit the second parameter it will do exactly what you want.

This function returns a string with whitespace stripped from the end of str.

Without the second parameter, rtrim() will strip these characters:

" " (ASCII 32 (0x20)), an ordinary space.
"\t" (ASCII 9 (0x09)), a tab.
"\n" (ASCII 10 (0x0A)), a new line (line feed).
"\r" (ASCII 13 (0x0D)), a carriage return.
"\0" (ASCII 0 (0x00)), the NULL-byte.
"\x0B" (ASCII 11 (0x0B)), a vertical tab.
