echo eregi_replace("([^\n\r \\./<>\"\\-]{$wordwrap})"," \\1 ","$1000");
// outputs $100 0

echo eregi_replace("([^\n\r \\./<>\"\\-]{".$wordwrap."})"," \\1 ","$1000");
//outputs $1000


For output, see:

I'm not sure what else you need. I can provide most things.

This is bcz of the special treatment that the "{$variable}"
construct has in PHP. Here's how the statement looks by the
time the regex parser gets ahold of it:

([^\n\r \\./<>\"\\-]100)

Which is going to replace "$1000" with " $100 0", as you
asked it to...
