RE: [PHP] eval();
Keep in mind, eval()ing code you pull from the database will also raise the
damage from a SQL injection attack or similar from a PITA
restore-your-database to a much bigger PITA format-webserver.

Sure.
Now you wanna go re-write all my code that pre-dates preg_* functions
being added to PHP? :-)
Un-paid? :-) :-) :-)
Cuz I probably still do have a while(ststr(...)) str_replace() loop or
two in there somewhere from PHP3.0rc2 days...
Yes, ereg_* were in then.
But they were kinda slow and I didn't undestand Regex then.
Hell, I barely understand it now, really.
There's a certain point where the Regex expression reaches a level of
complexity that I'm just not willing to accept in my code and call it
"maintainable"
/ */ is fine, of course.
But there's lots of times when I know there must be a one-line regex
to replace 10 lines of code, but I don't WANT to use it because I'll
stumble over that one-line Regex every time I have to change it.

So this should give you checkbox_name=on in a GET form. If it doesn't, your browser is very very very broken. [Probably Internet Explorer would be the one to get this wrong, if any of them do] B) I dunno what version of PHP you are using, nor what php.ini settings you have, but, at least in my version/settings: http://example.com/test.php?checkbox_name= isset($_GET['checkbox_name']) returns 1 Since HTTP and HTML have no concept of NULL, I'm not real worried that $_GET will have NULL values in it. I am certainly not going to pollute $_GET/$_POST/$_REQUEST by stuffing NULL values into them! If you want to do things that way, go right ahead.

No, it will return the entire matching pattern, not just the sub-

nearly always be a trailing space because of the part of my pattern
that defines a word will include it. It was simpler to use trim than to
make the pattern skip it. Did you actually try it?
No. I said that I was not that sure about this because I have not used
preg_* functions yet.
On the other hand, I think we have to place a caret after the first
slash.
Only if you insist that your string must start with a word - putting a
^ at the start would make it omit the first word if there was a space
in front if it.
I think It is OK what I said about the caret, but what we need to change
is the position of \W*:
Your suggestion: /(\b\w+\b\W*){1,$MaxWords}/
My suggestion: /^(\W*\b\w+\b){1,$MaxWords}/
We need the *first* ($MaxWords)th words.
Instead of preg_match(), I had to type preg_replace():
err. I think you missed the point here. You don't need all that messy
substr stuff at all. The preg_match already did it.
Sorry, you are right. Maybe I thought I was talking about the former
script I suggested...
What do you think if we use the script you suggested, but we change the
regex to what I said above? It will look like:
$MyOriginalString = "This is my original string.\nWhat do you think
about this script?";
$MaxWords = 6; // How many words are needed?
$matches = array();
if (preg_match("/^(\W*\b\w+\b){1,$MaxWords}/", $MyOriginalString,
$matches)) {
$result = trim($matches[0]);

No, because eval(), when passed string $str, effectively does this silently: $str = ""; and then passes $str to the PHP interpreter. Which is, in most cases, what you want, because you want to evaluate PHP code. However, if eval() is the answer, you're probably asking the wrong question.

Can you use AJAX to output an entire php-generated embed tag into a

something like:

qtplugin.cab">
EOB;
header('Content-Type: text/xml'); // ajax only seems to like text/xml
header('Content-Length: '.strlen($qtembed));
echo $qtembed;
?>
I am a bit new to Ajax stuff, but thankfully, have been able to make
simple examples work.
From the examples I have tried thus far , it 'appears' that Ajax
only supports sending/receiving elements like zip codenot entire
tags
Is there a way to 'curl' the html to see what 'xmlhttprequest' is
sending and receiving ?
Maybe I am going about this the wrong way and there is a better
solution?
I wanted to avoid pop-up windows, launching new html pages, and
iframes if possible.
Ultimately, I want to dynamically write an invisible movie embed tag
into an html document when called by some 'geturl' actionscript.
Basically, click a button in a flash movie, and the quicktime
player launches.
Instead, should I write a 'empty" quicktime movie tag into the html
document with the element, moviename, for Ajax to target ?
many thanks in advance :)

By the way, if you're able to use preg_* functions, I suggest you to use
this script instead of the former I suggested. What's the difference?
Let's suppose we have a string with typos such as "Mandriva , Red Hat ,
Debian" (the right one is "Mandriva, Red Hat, Debian", without spaces
before commas). The former script will find 6 words (because of the
spaces before commas), while the latter will find 4 words (Mandriva Red
Hat Debian). In this case, the former was wrong and the latter right.
However, the former doesn't not remove punctuation marks nor spaces
(tabs, fine feeds, among others); the latter will remove any character
which is a non-word character. If you need words + punctuation marks +
spaces up to the ($MaxWords)th word, this is my suggestion:
$MyOriginalString = "This is my original string.\nWhat do you think
about this script?";
$MaxWords = 6; // How many words are needed?
$replacement = preg_match("/^(\W*\b\w+\b){1,$MaxWords}/", '',

PHP doesn't now that it's PHP - it just treats it as text. You can

Eval is usually worth avoiding, but it will do what you ask.
Your display function could be improved:
function display()
{
$file = basename($_SERVER['PHP_SELF']);
require 'connect.inc';
$sql = "SELECT HTML FROM `$db`.`$table_editor` WHERE `Filename`

Then call it:
if ($contents = display())

This should be faster and safer than your original code.

You could get the regex to do the search and the extraction in one go:
$MyOriginalString = "This is my original string.\nWhat do you think
about this script?";
$MaxWords = 6; // How many words are needed?
$matches = array();
if (preg_match("/(\b\w+\b\W*){1,$MaxWords}/", $MyOriginalString,
$matches)) {
$result = trim($matches[0]);
echo $result;

It was probably replacing *TWO* spaces with one.
If so, it should really be in a while loop, because there could be 3
or more spaces in a row, and if the goal is only single-spaced
words...
I can hardly think of a better application for a regex:
$text = preg_replace('/ */', ' ', $text);

So you will most likely be using isset($_POST['checkbox_name']) rather

I classify using isset for checking for the existence of array keys
to be a bad habit as in some common cases it will not work as you
expect, for example:
(note it has no value attribute) If it's checked, you would get the
equivalent URL of "...?checkbox_name=", so $_REQUEST['checkbox_name']
exists, but may contain NULL, and isset would return false even
though it's there. A completely reliable check that will never
generate any warnings is:
array_key_exists('checkbox_name', $_REQUEST).
If you have several checkboxes in an array (using names like
name="checkbox_name[option1]"), you would say:
if (array_key_exists('checkbox_name', $_REQUEST) and is_array
($_REQUEST['checkbox_name'])) {
if (array_key_exists('option1', $_REQUEST['checkbox_name'])) {
echo "you selected option 1\n";
}
if (array_key_exists('option2', $_REQUEST['checkbox_name'])) {
echo "you selected option 2\n";
}
//etc...
}
