PHP textbook suggestions?

Looking for suggestions for a PHP textbook for an "Intro to Web Programming" class that will be using PHP5 and MySQL. This is a first-semester course, so no programming experience required. It would be nice to have a text that adhered to (what I see as) good practice using quotation marks... i.e. print 'The cost is ' . $cost; NOT print "The cost is $cost"; AND CERTAINLY NOT print ("The cost is $cost"); echo substr('abcdef', 1); NOT echo substr("abcdef", 1); I will be teaching, so a book that a student can-- before the class-- work through and understand is good-- doesn't have to be a traditional textbook! But it shouldn't be a reference manual either. c -- Chris Lott
