Yes, you may want to try this Secure HTML parser filter package. It
comes with parser and a filter class that validates HTML against an
eventually auto-detected DTD. It returns an array of tag and data
elements that you can use to rebuild a valid HTML document using the
RewriteElement function.

Lack of favicon.ico will show up in your logs if the file isn't there,
but it will do nothing to prevent your site from showing up.
Frameworks like CakePHP require additional files and database tables to
be created by the programmer, before anything will show up on the
screen. There are either omitted files or missing tables (or missing
table rows).

You may want to try this HTML parser class that comes with filter class
and an example script named test_get_html_links.php that does exactly
what you ask.

Thank you very much for this. It has at last provided the clue I was looking
for, and
after far too long I have got a trivially simple demonstration working. One
complication I
hadn't anticipated is that apparently I can only access functions in the
include file, but
cannot execute any code in it.
Thus when Halla.php read:
<?php echo '<p>Eng_test_'.__LINE__.' Hallejuha!! : </p>'; ?>
and I included it:
$ok = define ('HOST_PATH','../Engine');
$ok = include (HOST_PATH.'/Halla.php');
nothing happened.
When Halla.php read:
<?php function halla ($i) {
echo '<p>Eng_test_'.__LINE__.' Hallejuha!! : '.$i.'</p>';
return $i; } ?>
and I included it:
$ok = define ('HOST_PATH','../Engine');
$ok = include (HOST_PATH.'/Halla.php');
$ok = halla (7);
echo '<p> Returned '.$ok'</p>';
it did work. I presume that this explains your next comment, in that I am
neither reading
nor executing the code in the Include, so permissions don't come into it.

Yes; I have got already got all that working. Now I JUST have to convert my
main program
into one big function!
Will I still be able to access $_GET & $_POST variables, and set up session
variables from
inside this function? I guess I can declare them all GLOBAL?
Thanks, again,

Because you are assigning the result of the include to a variable. Try
include (HOST_PATH.'/Halla.php');
and it will work as you expect. And similarly for
define ('HOST_PATH','../Engine');

In short, are you looking for a program which listens on a serial port
and a network port at the same time, and places any data received from
either into a database?

Is there a way to round down to the nearest 50?
Example: Any number between 400 and 449 I would 400 to be displayed; 450 to 499
would be 450; 500 to 549 would be 500, etc?
The original number of subscribers is from a mySQL query and changes each day.
I am trying to present a factual statement: "There have been over ###
subscribers in 2009" type of scenereo.

Off the top of my head: divide the number by 50, run floor() on the
result, then times it by 50.
1. 449 / 50 = 9.whatever
2. floor(9.whatever) = 9
3. 9 * 50 = 450

It should be round() and not floor().
449 / 50 = 8.98
floor(8.98) = 8
8 * 50 = 400
round(8.98) = 9
9 * 50 = 450

I also wrote a function for that,
function round_to($number, $increments) {
$increments = 1 / $increments;
return (round($number * $increments) / $increments);
}
(Also published on php manual - round() )

Lets assume I have the string "cats i saw a cat and a dog"
i want to strip everything except "cat" and "dog" so the result will be
"catcatdog",
using preg_replace.
I've tried something like /[^(dog|cat)]+/ but no success
What should I do?
