PHP 5/MySQL Programming- P74

PHP 5/MySQL Programming- P74:computer programming has often been seen as a difficult and arcane skill. Programming languages are difficult and complicated, out of the typical person’s reach.

The only surprise is how simple the code is for this program. html head title Show Segment title style type text css body color red td color white background-color blue width 20 height 3em font-size 20pt style head body if empty room room 1 end if connect to database conn mysql_connect localhost Chapter 10 Connecting to Databases within PHP 344 PHP 5 MySQL Programming for the Absolute Beginner select mysql_select_db chapter7 conn sql SELECT FROM adventure WHERE id room result mysql_query sql mainRow mysql_fetch_assoc result theText mainRow description northButton buildButton north eastButton buildButton east westButton buildButton west southButton buildButton south roomName mainRow name print HERE center h1 roomName h1 center form method post table border 1 tr td td td northButton td td td tr tr td eastButton td td theText td td westButton td tr tr td td td southButton td td td tr table center input type submit value go center form HERE function buildButton dir builds a button for the specified direction global mainRow conn newID mainRow dir print newID is newID query SELECT name FROM adventure WHERE id newID result mysql_query query conn row mysql_fetch_assoc result .
