Just finished half the PHP QC1. That's the proofread after the copyeditor has been through. Did the conversion to Frame bugger anything up? Did the copyeditor think it should be "P.H.P." (she didn't). Mostly, though, it's occasion to find all the mistakes that weren't caught in the tech review.
Other than the usual stuff you're too close to see when you're writing (variable names wandering during an example, from $addresses to $array and back again), I found two good 'uns. "inheritence" (should be "inheritance"), and a tricky one involving interpolation.
The classic way to explain the need to bracket interpolated variables is:
$n = 12;If you leave out the curlies, you're trying to print $nth. That was the example we had in the book. Only I think the copyeditor changed it to say we were trying to print the $nth variable (i.e., $n in courier, th in roman). Um, no.
print "the ${n}th man"
Oh the tiny strange things that my life is suddenly filled with :-)
