You may need to use the inverse function, ord(), to get your codes into
numeric form. For example, ord('m') will return decimal 109. That's only
an example, since you should be able to send single characters to the
terminal as is.

A couple of thoughts. First precede all your mysql_* calls with the at
sign (@) to shut up the routines if they generate text. I had this
problem, and that was the answer.
Second, store your connection resource as a class variable, so you can
pass it around to the various routines. Actually, you're already doing
this, but I prefer to do so explicitly, as:
var $link;
at the top of the class.
I have a similar class for PostgreSQL. I also have routines like
"update", which allow you to pass a table name and an associative array
of field values. Same thing for an "insert" routine.

setjmp/longjmp calls in C, and they're a really headache to deal with.
If you don't use default or predone handlers, you have to put all kinds
of try/catch blocks around everything. They make for non-linear
execution, and I prefe

There are reasons to use setjmp and longjmp in C as well, but I only

It's a *nix timestamp number. Give it to date() this way:
date('Y-m-d', $startday)
And you'll see the date it re

personal recommendation for about the lightest weight of these is
CodeIgniter (codeigniter.com). Being lightweight also allows you to look
at its code and easily understand what it's doing and why.

take the time to buy a book or carefully research an item on the web.
And FWIW, php.net has better documentation than that of any
other package I've ever seen. I keep a browser tab open to php.net at
all times.

McDonald's is my *favorite* fast food! Are you saying there's something
less than healthy about it?
Sorry, I used to live in LA, and I had health food people up to here.
They were the sickest people I knew. So I took it as my personal mission
just want to have a copy of the website itself on the device,
you could either copy it to the document root of the webserver on the
machine, or mount it at a point within the doc root. Otherwise, the web
server won't see it as a website to serve up.

What is the fascination with using concat_ws()? Just say:
$name = $first_name . ' ' . $last_name;
or
$name = "$first_name $last_name";

reSQL. Can PDO be extended?
In any case, I just wrote my own driver class for each DB type, and then
a function which instantiates the appropriate driver with the
appropriate parameters.

Note: If you use array_push() to add one element to the array it's
better to use $array[] = because in that way there is no overhead
of calling a function.
But that's the only change I would make. Overall, I completely agree

Use CodeIgniter. It's about the lightest weight and relatively easy to
understand.

I want to stress that PHP is *not* a *visual* language. You have to sit
down with an editor and write it. Very unlike programs which allow you
to design tables using visual means.
Hope that helps.

kudos to Dan for setting the tone of the list. His replies are generally

ing the input easier in Perl or
Python, where you don't have to deal with variable initialization as
much. And both also have APIs for MySQL and PostgreSQL. And I believe
both DBMSes can handle databases of this size.
