If it's turned off, people will see your static content, and if it's on they'll get the full experience. Having alternative content is important because it allows Google to properly index your site. Finding a way to check if Javascript is turned on while still in server side is really unnecessary, since displaying alternative content and removing or hiding it client side works just as well as redirecting to an alternative page.

Hi,
It depends. What's exactly do you want to prevent? It doesn't seem like a
very big problem if someone tries to include an improper adderss or
nonexistent file, since that would simply make $data an empty string
(depending on your level of error reporting and whether you display or hide
warnings). If the included file decides to call ob_get_clean() or something
like that $data will be false. I can't think of what else you realistically
want to prevent.
Building a page with multiple templates is best done by using a good
template class. Allowing the inclusion of external PHP files from a CMS will
pose a risk if non-developers have access to the CMS as well. You're
basically allowing anyone to add (potentially untested) code to a live site
and I would recommend against doing it. If you want people to be able to
include, say, additional HTML content, use file_get_contents() instead.

Make sure the database connection is also utf8:
set names 'utf8';
Typically, you should keep everything in utf8 unless you have a very good
reason not to.
And as Peter mentioned, the proper way to escape MySQL inserts (that is, if
you're not already using a framework that does this competently) is
mysql_real_escape_string().

You might want to consider making the language dependent on the URL, e.g.
http://site.com/ru/pagename for Russian. Doing it this way certainly isn't a
bad solution, but I do strongly recommend against using define() and using
anonymous translation keys. Usually, you have one base language (which is
usually English due to its lack of special characters and ubiquity) from
which you work. You then either simplify your keys, e.g. 'user_welcome' =>
'Welcome, %1$s!', or make the keys the proper base language strings so you
can wrap everything in a language function.
In the latter case, you might have something like , and then if the current language is not English, the _()
function will make the appropriate lookup.
The advantage of this is you won't need to have a tertiary source to tell
you which MSG### corresponds to which piece of text.

Re: [PHP] collect string from string
You need to use the multiline modifier.
Try this:
preg_match_all("/^(\#.*)/im", $my_string, $matches);
print_r($matches);
The result:
Array
(
[0] => Array
(
[0] => # {{uncountable}} The dried leaves or buds of the [[tea
plant]],
[1] => #: ''Go to the supermarket and buy some '''tea'''.''
[2] => # {{uncountable}} The drink made by [[infuse|infusing]]
these dried
)
[1] => Array
(
[0] => # {{uncountable}} The dried leaves or buds of the [[tea
plant]],
[1] => #: ''Go to the supermarket and buy some '''tea'''.''
[2] => # {{uncountable}} The drink made by [[infuse|infusing]]

The biggest part of learning any language is becoming able to creatively solve problems within its realm of possibilities, and that's something you can't really learn just by reading and solving textbook problems.

Are you sure that the PHP file itself is utf-8? Could it be that you manually set the text encoding to something else in your browser, causing it to remember that setting?

Yes, ' is the same as a single quote. But let's say you set up your
page like this:
http://pastie.org/932923
Submitting the form will change the $input variable that's also added to the
Javascript below. So in theory, you should be able to submit, say,
'+window.very_important_variable+' in order to get an alert with
the secret number 255 in it. But when submitting that text in the form, the
& actually gets converted to &, causing the alert() to literally print
the string '. When submitting a real single quote, it gets converted to
\', printing a literal '.
The only way to get to the window.very_important_variable is by removing the
htmlentities() function in the PHP code. The test case you added is
incorrect, since properly sanitized input would never have an actual,
non-escaped ' in it.

I don't have to manually set the encoding to get the Farsi characters to show up in either of these links. I don't know why it wouldn't work for you.

There's a double quote " right in front of the $hours variable on the fourth line. That's an unterminated string literal, a syntax error, which would cause PHP to abort entirely. Your php's error log probably has a message in it to this extent.

Some parsing is very useful to the user, since overtly technical information is just confusing. The error should never be something that the user himself can avoid (since you're supposed to have error checking and handling before the user submits), so your error should make this clear to him. It helps to let him know that the developer has been notified and that he can try again later. Michiel

By the way, if you're stuck on 5.2.10, you could simply cast the result to
array:
var_dump((array)json_decode('{"_urls": ["a", "b"]}'));

Maybe more elegant since it's extendable to more than 2 states if required. Michiel

You're right, but this is about how 5.2.10 ignores the second parameter and
always returns a class, which appears to be a bug. I'm not sure which other
versions have this same problem, but 5.2.11 has correct behavior, which
seems to suggest they found and fixed it by then. I can't find an entry for
this problem in PHP's bug database, however.
My suggestion to typecast the result of json_decode() should only be
followed if you need an array and are required to work with version 5.2.10.

Yep, it's that easy. :-)
// array(1) {

var_dump((array)1);

I'm running Safari, which most definitely will support whatever advanced features you put in there, and I'm being blocked. Putting aside the level of standards compliance of your site, you really should blacklist browsers instead of whitelisting them. Sites should never become inaccessible if your browser lacks features, and even if the entire site revolves around some fancy Javascript, you should at least provide a "go ahead at your own risk" link in case you're accidentally shutting out the wrong browser. Here's an example from a site I made a while ago which mimics the workings of Gmail. It's accessible to screen readers through alternative content, and if you're trying to visit using IE6 (we consciously decided not to apply browser fixes for it), you get the following message: http://wedemandhtml.com/tmp/tag_ie6_is_unsupported.png Michiel

This is a very well known talking point that can easily elicit a lengthy off-topic discussion, and I don't think anybody is really interested in that. Again, this is just my opinion, but while it's okay to talk about things other than PHP on occasion, I don't really see what use this has other than provoking a response from someone. Please be considerate is all I'm asking. Michiel

This can easily be done in Javascript. The only reason to build an image generator is if the images need to be used in a non-browser environment, e.g. sent to the user in an e-mail or enclosed in a PDF. At minimum you need all colorized images of the jewels, but you could even do with one single image and colorize it using . Too bad that's not supported in anything other than (iirc) Firefox and the Webkit nightly. Michiel

Xpath is indeed the way to go. For example...
/* .. your code.. */
$data = file_get_contents($url);
$inDoc = new DOMDocument();$inDoc->preserveWhiteSpace =
false;@$inDoc->loadHTML($data);
$xpath = new DOMXPath($inDoc);$xlinks =
$xpath->query('//d...@class="b"]/a');for ($a = 0, $z =
$xlinks->length; $a < $z; ++$a) {
$link = $xlinks->item($a);
$href = $xlink->attributes->getNamedItem('href')->value;
}
To be safe, you should use an ID instead of a class, though.

Hello,
Actually, the problem is that you're not just escaping the content of the
insert, but the entire insert statement itself. You need to only escape the
data, not the query. To properly prepare your statement, you need something
like this:
$sql = "INSERT IGNORE INTO `table` (`value`) VALUES
('".mysql_real_escape_query($my_serialized_string)."');";
Note that the mysql_real_escape_string() function is *not* affecting the
apostrophes (') that delineate the value.

There really aren't that many differences between them. Yes, a lot of legacy elements were removed, but those that program in valid XHTML tend to not use them anyway. The real reason why target is a little ill-conceived is because not all target devices are able to use it in a valid way, e.g. phones with simple web browsers. But if it was never your intention to support those devices, using Transitional and the target attribute really isn't an issue. Michiel

As it is right now, your index.php is hardcoded to load the "messages" controller. That shouldn't happen. You should refactor your application so that the index.php does nothing except load the config, parse the request and then load the appropriate controller. And you should move the "templates" directory to the "application" directory (and maybe call it views for clarity). Everything that the user writes should be in one directory so that he can update the underlying system without deleting or overwriting files that he made. Regards, Michiel
