Re: How do I display apostrophe in PHP generated form?

First, thank you for the very prompt reply; your solution works.

I have always found this list to be very helpful and friendly and you
have continued the tradition. 

But, I don't completely understand why this was necessary.  To me, it
looks like a simple PHP echo command so why would I need to escape it
at this point.  There was a problem earlier in this project with data
passed by JSON and I had to use htmlspecialchars() to relay the JSON
data to the next script but that was the reverse of what I am doing
here.  I had seen htmlentities() (and htmlspecialchars() which is
noted as equivalent in the documentation) in my research but it didn't
seem appropriate because I was considering this as an echo function.

What am I failing to see?

Regards, and thanks again.
