Good day, No, that's not it.
It's just a simple matter of order of operations. You have an expression- that expression needs to be evaluated into one thing, and that one thing is then passed to echo() as the single argument. I'm not a php expert, but evidently the "." operator is evaluated before the "*" operator, which in turn is evaluated before the "+" operator. Perhaps it would be easier to understand if you thought of the "." operator like the exponent operator in math- it is evaluated before "*" or "+" is. ============================ Darren Gamble Planner, Regional Services Shaw Cablesystems GP 630 - 3rd Avenue SW Calgary, Alberta, Canada T2P 4L4 (403) 781-4948 -----Original Message----- From: Billy Harvey [mailto:[EMAIL PROTECTED]] Sent: Friday, January 18, 2002 12:07 PM To: Darren Gamble Cc: php Subject: RE: [PHP] bug in echo function?

Hmmm - so my assumption that the concatenation operator between the strings gives them a delination equivalent to listing this as three separate echo statements is incorrect, I take it. Shouldn't the echo function process it in this manner from a standpoint of consistency? Thanks for the clarification.
