Actually yes. But allow me to retort my whimsical friend who is so quick to sneer. ;-p Because I wanted some way to know that each of the millions of records was being imported. A "progress indicator" if you will. One that quickly illustrates that "yes, something is still churning away, even though it might be taking minutes, hours or *gasp* days to process". I didn't want to print out a single "." for each one, as that still just takes up pages and pages of scrolling as they whiz by. I didn't want to use the new record ID, as that takes up a wasted SQL call to get LAST_INSERT_ID(). So a spinner was a likely candidate. It sits in place and rotates 1/8 turn for each record inserted. As errors occur, I can spit them out where I'm sure to see them (or log them to an error log) and they won't get lost in a maxed out scroll-back buffer. Plus it looks freakin' slick as hell and gives the appearance that I am smarter than I am. *grin* > besides, modulus 8 is done by one single instruction - of > which a modern processor does some three billion per second. Perhaps. But I prefer to write optimized code. I am used to it from when I used to code 3D games, where every microsecond you can shave counts. Even now, as I design LAMP tools, at the enterprise level, when you shave off a few microseconds from each iteration, and multiply that times large datasets, you quickly start to shave off seconds from every page load. It matters. I believe that if MORE people thought this way, then there would be less bloated software. How come it is that with all those three billion instructions per second I *STILL* have to wait for ANYTHING to do ANYTHING? Seems to me it should be instantaneous... Food for thought. P.L.U.R.
