First, let me say this is a VERY VERY VERY bad idea for security 
reasons.  Never use user input for stuff like that.

Second, from the typos you have above, it is clear your example shown 
here is produced by typing rather than not copying and pasting.  So we 
can't diagnose what's really happening.

Third, putting the quotes around $from in that last line is not 
necessary.

Fourth, it seems like it's actually working because the call to file() 
is not throwing an error, right?  [Or are you going to pull one of 
those "Oh, yeah, I forgot to say, the Check Engine light is on" 
situations that happened on "Car Talk" a few weeks ago?]  Thus if 
$lines is empty, the file is empty.
