Don't eval the string - just deflate it.

By eval'ing it you are asking php to execute what is in the string. As it includes an echo - it is going to output the echo.

Also the way you are using your preg_replace is confusing.

You say you want to output hello - but you don't have any echo statements in your code sample - you also have the input string as the second parameter - which is the replace ment parameter.
It should be

preg_replace(pattern, replacement, subject)

What are you wanting out of the preg_replace?
