[PHP] Detecting resolution

[PHP] Detecting posts from outside site
Also, speaking of detection, I made a small script that can protect against
people downloading your site's forms, modifying their new local copy (and
putting an absolute URL in the form's ACTION attribute), and then posting
data using the botched form. If it's bulletproof, then I figured this could
help some of you out. If not, I welcome comments (I'm a little bit hesitant
of calling things 'bulletproof'). $http_referer (lowercase) is the
parse_url() of $_SERVER["HTTP_REFERER"]. Some local mucking up can give you
the format you want for it.
if((count($_POST) > 0) && (!stristr($_SERVER["HTTP_REFERER"],
$http_referer))) {
unset($_POST);
$evil = "postedfromoutsidepage";
}
Then, you can test for $evil when you need to print an error message or
decide whether or not the data is proper.

[PHP] Chmod funk
This line of code:

Produces this error:
Warning: chmod() [function.chmod]: Operation not permitted in

What I'm trying to do is determine if Constants.inc is readable. If not, I
want to change its permissions. At this point, I'm not worried about if it
exists or not.
I'm not sure why I can't set it. The owner and group for the file are both
'mastersite', and my PHP is running as 'root' (I know, I know, not a good
idea, but I'm in the testing phase right now, and if it's hacked at the
moment, it's not a problem). Does anyone have a possible explanation? The
file perms for Constants.inc are currently set at executable for all.

[PHP] htmlentities()
I seem to be having trouble with htmlentities(). Maybe someone has a clue I can
borrow. Here's my function:
function FitForHTML($string) {
$asciitable = get_html_translation_table(HTML_ENTITIES);
$string = htmlentities($string, ENT_COMPAT);
$string = str_replace($asciitable[chr(255)], "ÿ", $string);
return $string;
}
When calling this function with the following data: é[a club]+ <>
I get: é♣+ &
(I didn't send this as Unicode. The ♣ was originally a club character.)
Maybe I'm not looking in the correct area, but when I do a search in Google Groups, I
get one message (well, two: one in English and one in German or some language that
uses a lot of z's and c's), but that doesn't solve the problem.

Re: [PHP] crontab
> Can I run a php script in crontab? > Do I echo or print? > Anyone doing it? This is a serious security hazard. However, what you could do is have a PHP page set cron settings (such as name of file, location, frequency, and importance), then have another cron job (running at a decent frequency) do the organization. However, this is still a security flaw, as hackers can just take a look at your cron jobs and get in and run their own in place of yours. Probably no more a flaw than normal, though, as if a hacker can get in to replace your cron job, they can get in and run any number of things anyway. Make sure to hard code your cron jobs, as having a downloadable page is a bigger security hazard. You don't want the PHP page to do this itself, because it will have to run as root. I did this one time, and if I'm allowed some time to get my page up, I can e-mail you some instructions. What you'll need is a PHP page, a txt file (for the settings) and a cron job that will read the file and do the necessary steps to arrange the cron jobs itself. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Dollar signs in values
How is it I can properly get PHP to represent dollar signs when putting it into HTML? I know that dollar signs denote the beginning of a variable, like $reference or $ftpstream or whatever. However, I have a text file that contains (or can contain) values with $ in them. When I open the file and grab those values, then stick them onto my HTML page, they get unpredictable results. Is there a way I can escape them or such?
Re: [PHP] Dollar signs in values
> Escape them with a backslash: > > $text = "The amount is \$400.-"; All that does is print \$ in my HTML. What's going on is that it will put, say, RR$T into a file when that's typed into a textbox or any typable form control. That's properly saved in the file. So the file will contain RR$T. When it's output, it could be RR, or RR$T, depending on some unpredictable factors (haven't figured it out). By adding a slash, what gets saved in the file is RR\$T, but what gets output could be RR\ or RR\$T, depending on those same factors. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I even went to the 'trouble' of copying and pasting $frequency wherever I
needed.

No, I'm trying to access it inside the function. This is what I have (or an
example, since I don't have it right in front of me right now):
function func($a = 1, $b = 2) {
print("[$a]");
}

[PHP] Strtotime weirdness
When I have a date, March 31, 2003, and I want to subtract 1 month using strtotime, I find it will literally subtract a month, so March 31, 2003 minus one month will result in February 31, 2003, or rather, March 3, 2003. Is there any way of making March 31, 2003 minus one month equal February 28/29, 2003?

Re: [PHP] Date Problem - Last Day Of Month
> Hi there, can anyone tell me how to fix my code so that on the last day of
> the month, my code doesn't repeat the months...
I'm not sure what you mean by this, but I can be a moron on this list
sometimes and the clear answer usually comes to me about 2 seconds after I
hit the send button. Do you mean that you don't want any months in the
SELECT control when it's the last of the month? Or you don't want the
SELECTED attribute in the OPTION tags? As far as I can tell, you're not
repeating any months, but you're only listing them once.
Try this (and IMHO a *slight* *slight* improvement in clarity, but again,
that's my HO):
" . date("F",mktime(0,0,0,$counter,date("d"),date("Y"))) .
"";
}
}
I adjusted it so that you only print out the SELECTED attribute if it's the
current month, and I called $i as $counter, because, to me anyway, it makes
it clearer what is the $counter. If $i works for you, though, there's
nothing wrong with that, and it's not that it's unclear anyway, what with it
in the FOR loop only a few lines earlier. (I'll shut up now about $counter.)
Anyway, I added a comparison above that said if the current date is less
than the last day of the month, then print SELECTED. That's assuming I have
your question right in that you don't want to select the current month if
it's the last day of that month. Otherwise, if I'm wrong, you can take that
comparison and put it just about anywhere.
Help? Doesn't? Am I a complete goof?

[PHP] Question on response time, SQL vs. PHP
I'm trying to do a count(*) in SQL. Would it be faster to do a or b below? a: just do a simple query, and use mysql_num_rows() to return the row count; or b: do the count(*) and use mysql_fetch_row() to return the result. I guess it would have to do more with SQL response time (is it faster to grab the count and then the row, or all rows in question and then do a count in PHP).

[PHP] HTML-based mail with PHP
Now, this may be more of an e-mail question than a PHP question. For that, I apologize. I'm having trouble with some HTML-based mail with PHP. It's not the regular thing where I can't get it to use the tags instead of just printing them. That part's fine; it comes out HTML-based. My problem is the way it's not accessing a certain image. I get a broken link instead of an image at the top of my e-mail. I had it print the URL at which it should find the image, and then cut and paste that in my browser, and the image comes up fine.

[PHP] Date conversion problems
Having a little trouble with converting dates.
I have, in my database, a bunch of dates stored like this: -M. Month is
obviously the number of the month (5), not the name (May).
I want to convert the format to MMM, (ex: May, 2002), so I used the
mktime function. Basically I extract the date with a regular MySQL query,
then explode the date, and my components look great. However, when I put the
components into my mktime function, sometimes it'll work and sometimes it
won't. It won't work if the date is too far off in the future (2085, etc.),
but I'm not exactly sure what the cutoff is. If it's recent, say 2005, it
works fine.
My code is this (after grabbing the query results):
$enddate = explode("-", $datereuslt[0]);
$fullenddate = mktime(0, 0, 0, $enddate[1], 0, $enddate[0]);
$finaldate = date("M, Y", $fullenddate);
Any ideas? Alternatively, if anyone has an easier way of doing this, I'm all
ears.

That's what I thought I might have to do. It's an alternative, but a clunky
one. Thanks Matt.

Easy enough. One of those things the programmer may not spot, but a casual
observer might. In line #2, you have a single =. A comparative = is a double
equal (==). The line should read "if($day == $system_day){". A single equal
will assign the value; a double equal will compare the two.

[PHP] Ridding myself of HTML tags
I've got a lil problem with HTML tags. Here's the description. My site accepts HTML files by upload. A lot of these files are written in MS Word and then saved as HTML files from that. MS Word likes to put a bunch of garbage at the beginning of the file. Now, when users upload their HTML files, my script goes and striptags all of the unnecessary junk in there except it can't rid all this junk (HTML, XML, CSS, JavaScript) at the beginning of the HTML file. Some of these tags span multiple lines, and my script goes through line-by-line, so it won't identify these as tags. Is there a simpler fashion? I don't need the junk about style sheeting and stuff, because I have a style sheet that will take care of styling the files the way they should be. I don't want the extra tags, even though they're invisible to users when they web-view, because these are e-mailable files (for HTML mail, it's fine; for text mail, I need to strip it down and that's the problem). = Just in case, I've included the HTML code below: http://www.w3.org/TR/REC-html40";> Test test test Test test test Fdjfkasdjfkla Fdjkslafjdklaf Fdasfdfasffasdfdaadfdfs Dfsdfs Hi Jfdklas -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Two PHP questions
First of all, what exactly is get/set_magic_quotes_runtime?

Does it get the magic_quotes setting at runtime, before anything has been set_magic_quotes_runtime'd? I sort of get that it has to do with returning slashes with quotes in a function as opposed to doing it when a function is called. Any clarifications? The only comment on the PHP list says that it's being turned off, so I guess it's not that important. Secondly, is there any way of counting how long in pixels my page runs?
