Re: [PHP] variables in CSS in PHP question/problems
Surf directly to your CSS URL and see what happens. There are several possibiliies: #1. Your CSS has ?php ... ? in its output, because you have not convinced your web-server to run your CSS file through PHP to compute the dynamic result. You need something like this in .htacces: File whatever.css ForceType application/x-httpd-php /File whatever.css should be your CSS filename. application/x-httpd-php is the default, but your webhost/httpd.conf could use ANY mime type it felt like using there. Read your httpd.conf to figure this out if it's not the usual (above) Once you get your web-server to pass your CSS through PHP and spit out the dynamic CSS that you desire... #2. Your CSS has what you expect in it, but the browser thinks it's an HTML document, and shows it as such. This is because in php.ini your default Content-type is text/html. But when you spit out your CSS, with the PHP dynamic content to it, you need this at the very tip-top: ?php header(Content-type: text/css); ? so that the BROWSER knows that you are sending CSS. Note: Some browsers may *ignore* the Content-type and assume from the .css URL that it is CSS. That's pretty broken, but they are trying to help the web designers who can't configure their web server to send the right Content-type for .css files. #3 Once you have done all that, there is a VERY good chance that your browser (especially IE) has cached the old .css file... You may need to hold the control-key and click on the Refresh button, or hold down SHIFT (or is it ALT?) and control-R for reload in Mozilla-based, or ... Actually, if you surf directly to the CSS, and reload that, as in #1 and #2 above, the browser should do the right thing. But the problem remains that as you change your CSS dynamically, if the browser is caching the OLD CSS... So now you may need some no-cache and Last-modified headers as well. #4 You are on your own to fix the 50-line OOP mess to solve a 1-line problem... :-) -- Some people have a gift link here.

Re: [PHP] Using a reentrant form

To validate a page, I set the form value to the page name the

Is there a disadvantage to this approach?
If a malicious user is TRYING to mess you up, they could easily edit a
copy of the form on their hard drive, and change looped to
interesting and obvious values that will probably break your
application:
0, -1, 42, ' 1; drop table mysql.user'
spring to mind as intereting values to cram into there. :-v
Consider, however, if you put an un-predictable random token in the
first form output, and log that token in your session (or DB) as
valid
After the first submission, mark it as used
At the point, the user cannot mess you up, unless they are good enough
to guess the 1 in a billion chance of another valid unused token.
See http://php.net/uniqid and http://php.net/md5 for how to generate
an unpredictable unique token for this use.
An SQL-injection attack is still possible, but an md5 is always 32
characters, so one of your sanity checks can be:
$token = $_POST['token'];
if (strlen($token) !== 32){
//log their IP or whatever, because they almost-for-sure are bad guy
die(Invalid token. Loser!);
}
$token_sql = mysql_real_escape_string($token);
$query = select used from token where token = '$token_sql';
used is a boolean. They either used it already, and you should ignore
the re-POST (or whatever you want to do) or not,and you should process
it and do:
$query = update token set used = 1 where token = '$token_sql';
The $_SESSION version is even easier...

Re: [PHP] dst and strtotime

I would recommend checking the OS for recent DST related patches, and figuring out why one function thinks your computer us in EST but the other one thinks your computer is in EDT, because adding a day is just a band-aid, not medicine.

Re: [PHP] question regarding form filtering
I use PCRE for filtering all the time.
As a general rule, be sure you are using a pattern that says allow
these valid characters and not one that says deny these invalid
characters.
You never know when some user will send Unicode or something so far
outside what you expected that your deny invalid won't catch it.
allow valid insures that ONLY the cases you thought of as valid, are
valid.
That said, sometimes the Right Thing to do is to deny invalid
character, such as newline in anything you are cramming into email
headers, as the spammers send out entire emails crammed into your
Subject box on form-mail, and then you send out their email for
them, as a side-effect of your attempt to send valid email. Play with
an SMTP server and send it some emails by hand to see how this
works...
You'd have to be getting a heck of a lot of traffic and have a *TON*
of inputs with PCRE being called on them for it to be any significant
drain on resources.
I daresay you couldn't manage to do it at all in a real-world
scenario, but I presume somebody somewhere has somethng weird enough
where the PCRE check is too expensive...
The odds that you have that are about 1 in 1,000,000 though.

Ok so whats wrong with good ole:

Am I going to get a performance hit if I validate all my fields with

As I see it I am only calling one function (ok 2 with the trim()) to
validate my form data.
Just wondering what you all thought about these different methods, and
what
approach suits best a given situation..

Their meter-reader-in-training however, misread the meter, and they decided that my electric bill was: US $9,443.78 Yes, really. I live in a one-bedroom apartment. My usual bill is like $30 in winter, up to $100 in hot summer months with window A/C going full blast all month. (I hate muggy heat.) I don't think I could put any gear in here that would use $9K worth of electricity in one month without the gear bursting into flames! By the time I spotted this error, and called them it was Friday after 5 pm. The phone monkeys all agreed (both bank and Com Ed phone monkeys) that it was obviously a mistake, but they could do nothing until Monday. Except the one who *thought* she could, only it turns out she couldn't reverse it out because it was a mistake of over $5K, and only a manager can reverse out a $5K or bigger mistake, so I'd have to wait until Monday. At no point did any human question the utter impossibility of this charge being correct -- They only said that they couldn't fix it because things usually don't go this wrong, and they weren't permitted to fix it as a matter of policy. So not until 5 days after the event did I get my money back. The United States Postal Service never actually delivered my statement, by the way, so I didn't really have a chance to head this off in advance.

So, no, Jochem, I probably wasn't having a better day than you that day. :-) Take heart. Your day could have been worse. I doubt the Sears Tower spends $9K on electricity in a month. Maybe some full-up monster data center... Does anybody know of any valid electical monthly bill (not counting something in arrears on previous months) of over US $9K? Sheesh! You *know* they have all kinds of red flag checks to protect themselves against scammers, schemers, and just plain no-payers, but I guess they don't give a [bleep] about protecting *my* money, with a simple sanity check. :-( Lord knows they can't even do an estimated bill right -- When they can't get in to read the meter, they routinely estimate it at either $50 (a bit high, but okay) or $8.xx. I dunno why their algorithm likes 8 so much, but this has happened once or twice a year for 22 years. It got to the point, before autopay, where I just ignored their estimate, and sent in my estimate, so I wouldn't end up in arrears. I'd have a credit until they read the meter, and then they'd figure out I was right, and I'd be caught up. So they can't do a simple estiment. Apparently, every Com Ed programmer skipped Home Ec. And 5th grade math. And 6th grade. And 7th, 8th, and most of high school math. Forget college. Because estimating a bill is about as simple as it gets...

RE: [PHP] Re: question regarding form filtering
I personally would not presume that PHP and JS regex patterns are 100%
compatible...
Store a separate pattern for each.
And, actually, the PHP check might be more involved than the JS check.
For example, if the users is making up a password, and this password
has access to something that's actually sensitive and worth protecting
(money, medical records, private matters)...
You should probably have JS and PHP to check that the password is long
enough, has mixed alpha and digit, that the password and confirmation
match, that neither password nor username contains the other as a
substring, etc.
But in PHP you'd probably *ALSO* want to check against a database of
words (say the one in /usr/share/web2, Webster's 2nd Edition
dictionary, now in the public domain) and make sure they did not
choose a simple word.
You almost for sure do *NOT* want to attempt to send the entire
Webster's 2nd Edition dictionary to the browser as JS data so that the
JS can check. :-)
I suppose you could do a Web 2.0 Ajax-y thingie for that...
At any rate, the validation in JS may not always be exactly the same
as in PHP, even if their PCRE patterns are 100% compatible, which I
doubt.
For anything that really matters, your sanitation probably ought to be
custom-tailored rather than off-the-rack anyway...
Plus, the easy ones are easy, and the framework probably won't handle
the hard ones, so what's the point of the clutter of the framework?
So I personally wouldn't even go down this road.
I expect many on this list to disagree with the preceding 2 paragraphs.
YMMV

Why Windows would be this weird, and let you create a file you cannot

If it's a multi-user Windows box, try logging in as the user PHP runs
as, which is IUSER_machinename, I think, on some Windows boxes...
exec() also takes 2 more arguments, which pass back output and error
code.
If Windows is giving any kind of error message and or OS error code,
you can get them by using those 2 args.
Do this first, actually, as it is better than just guessing what went

you must specify the protocol, curl currently support the http,
https,ftp, gopher, telnet, dict, file, and ldap protocols(see

if the protocol you use is not supported by curl, you have to find
another way :(

Re: [PHP] PHP URL issues
There are lies, damned lies and statistics. Had he known about benchmarks! I have already tried different ways of producing output and I completely disagree that concatenating the pieces and then echoing them is the best. In a first try, I found that echoing the separate parts as arguments to echo with commas in between was the fastest and variable interpolation within double quotes strings (or heredoc) was fastest than concatenation. Nevertheless, in a later trial, the numbers which were so clearly in favor of echo with multiple arguments, turned only slightly better, not enough to justify the loss of flexibility of building up a string first and having the option of manipulating it. This last sentence was confusing, lets see. When writing functions, you might either have them do the echo themselves or returning a string. The first is fastest, the second offers flexibility. If the first is really much faster, I'm willing to do away with the flexibility, which is no more than a potencial benefit, since 90% of the time I might have nothing at all to do with the return value of the funcion and, if really needed, I might use output buffering. Neverhteless, if the straight echoes are not that much faster, I'd rather keep an ace in my sleeve and go with returning strings. In my first trial, the result was conclusive, it was about 4 to 1, in the second, it was about 20% faster. The first was done on my own personal machine, a Windows machine doing nothing else, the second on my ISP shared hosting with an unknown load. I might say that my test on my own idle machine was the most representative, since it didn't have to deal with external issues such as competing for external resources, but then, that competition is really part of life. Though avoiding the memory shuffling of doing many string concatenations, doing echoes with multiple arguments might require the interpreter to negotiate access to IO buffers more often than building the whole page in memory and then getting it echoed just once. And I am sure that the way Windows and Linux handles IO with Apache is quite different, so, which benchmark is really representative? I am sure that some benchmarks are quite representative, independent of platforms. For example, it would make sense that doing an exact equality (triple =) should be faster than a plain equality. The first fails straight away if types are different and in no case is any conversion made. In the second, if the types don't match conversions need to be made first (after figuring out which one to make) so logic indicates it should take longer. Nevertheless, I don't feel like testing it out since the results, as my previous experience indicate, seem to be so uncertain. I'm not even arguing whether it makes sense or not in trying to shave off a few ticks of the clock. I am sure that a machine handling who knows how many users requests simultaneously will appreciate any little help, actually, I'm not sure I am actually looking for answers because, as far as I know, the answer is: it depends Satyam - Original Message - From: Richard Lynch [EMAIL PROTECTED] To: Steve [EMAIL PROTECTED] Cc: php-general@lists.php.net Sent: Wednesday, March 14, 2007 10:07 AM Subject: Re: [PHP] PHP URL issues On Tue, March 13, 2007 9:31 am, Steve wrote: This may or may not help, but here's a few things to note: 1) I would avoid placing variable output in double quoted strings.

I would recommend checking the OS for recent DST related patches, and figuring out why one function thinks your computer us in EST but the other one thinks your computer is in EDT, because adding a day is just a band-aid, not medicine. I agree, already said this but the dst update seems fine on the system, and its kinda hard to mess up. And it only needs an hour to kick it back into the right date I found. time() and date() return correctly, its just strtotime that pulls from EST instead of EDT for some reason Quite strange, but it is fixed in PHP5, so nothing to worry about i think. If you don't want to upgrade, you can use the fix i provided, It doesn't harm. Also you might be able to set the timezone to something outside a EST/EDT region.

As it is, I can save to an NFS or GFS file system, and be redundant that way. Talk to Jason at http://hostedlabs.com if you haven't already. I just did, he's using memcached not MCache. The name space for this class of project is fairly limited. He's rolling out a distributed redundant PHP architecture using your MCache as an almost turn-key webhosting service. Not quite sure exactly how he's makeing the MCache bit redundant, but he's already doing it. He's using memcache, which is redundant, but it doesn't do what MCache does. The memcached program is strictly a cache for things SQL queries. MCache is more like an object data store. Here is an explanation of how it works: http://www.mohawksoft.org/?q=node/36 NB: There is a typo in False Scalability section: ... but regardless of what you do you, every design has a limit. I took me a few minutes to see the typo even after you posted it. Thanks. What would you be looking for? How would you expect redundancy to work? In the ideal world, the developers are also working as an N-tier architecture in their Personnel Org Chart. :-) One Lead has to understand the whole system and the intricacies of your system, as well as its implications and gotchas really well. In an ideal world the Lead can then arrange things so that other Developers (non lead) can just program normally and have little or no impact on their process to roll-out to the scalable architecture. This is not to say that they can squander resources, but rather that if their algorithm works correctly and quickly (enough) on their dev box with beefy datasets, it should seemlessly work on the scaled boxes, assuming the datasets are not dis-proportionately larger comparing hardware to hardware pro-rated to dataset size. Yes, if the algorithm is anything bigger than O(n) this is not really safe but it's a close rule of thumb, and you can generally figure out pretty fast if your algorithm is un-workable. At least in my experience, if I can get it to work on a relatively large dataset on my crappy dev box, the real server can deal with it. So the less intrusive the redundant architecture can be, the better. I think a lot of people go completely overboard with redundancy. Yea, you need a load balancer and multiple web servers, but outside some hypothetical requirement of never any down time, I can't see much value in trying to create a single 5 nines system. If you can't deploy two independent service platforms, you will most likely suffer a failure somewhere. I think the big focus should be ensuring data integrity and fast recovery in the event of a failure. I mean sure, if you have the capital, go for it, but you can save a lot of money on your data center if you take a more rational view of downtime. Documentation of exactly how it all works is crucial -- If it's all hand-waving, the Lead will never be able to figure out where the gotchas are going to be. I'd also expect true redundancy all across the board, down to spare screws for the rack-mounts. Hey, a screw *could* sheer off at any moment... :-) Like I said, a lot of people go nuts about redundancy. Multiple data centers on a few different continents. US, Europe, Asia, India (which seems to have caught the American consumerism big-time lately...) Australia... Probably need 2 or 3 just in the US. That really is the *only* way to prevent down time. Some folks need WAY more bigger farms than others. Offer a wide variety of choices, from a simple failsafe roll-over up to sky's-the-limit on every continent. [Well, okay, you can probably safely skip Antartica. :-)] I'm not sure it makes sense to try to target huge web farms. That really is a different problem. Think about a SQL database. As long as you can replicate to a hot spare, most web farms settle for that. A truly distributed SQL database cluster is a big deal, and most sites won't ever need it. I'd like a status board web panel of every significant piece of gear and a health status in one screen of blinking lights. :-) If I have to be the one to SysAdmin the things, make that a control panel as well. Okay, in reality, I would *not* be the one to SysAdmin that stuff, as I would still need to hire a guy actually qualified to do that. Which is why we're working with Jason (above) who's essentially our out-source SysAdmin guy taking care of all this hardware and redundancy stuff so we can focus on our WEb App from a business perspective (mostly) instead of constantly fighting with hardware.

Re: [PHP] cannot load mysql extension - PHP Installation on Vista/Apache
You're probably on the right track here. I was doing some googling and I came across someone running Apache/PHP/mySQL on a Windows 2000 computer and was getting the exact same error. They found out it was a Security issue since administrative rights were not being delivered to required applications. I think I have a similar issue. I recently upgraded from XP to Vista and I run the Apache Web Server/PHP/mySQL as a testing server on my home system for my personal websites which I host on commercial servers. I don't think I would want to revert back to XP due to this single issue, since everything else is working fine and I like to learn get my hands on new technologies. I'd rather like to find out solutions to existing problems. I did see that Vista has (in some ways, quite unnecessarily) upped security, and I had a feeling this has something to do with what I'm facing. I'm just not sure how to make php.ini or the mySQL DLL extensions get administrative privileges while Apache tries to access them. Thanks. On 3/14/07 9:54 AM, Tijnema !

Store a separate pattern for each. Fair enough, beats writing a new function for each :) And, actually, the PHP check might be more involved than the JS check. For example, if the users is making up a password, and this password has access to something that's actually sensitive and worth protecting (money, medical records, private matters)... Not yet but maybe future clients ? ;) (archived) You should probably have JS and PHP to check that the password is long enough, has mixed alpha and digit, that the password and confirmation match, that neither password nor username contains the other as a substring, etc. But in PHP you'd probably *ALSO* want to check against a database of words (say the one in /usr/share/web2, Webster's 2nd Edition dictionary, now in the public domain) and make sure they did not choose a simple word. Good idea, sounds like plesk internals here.. I'll most definately keep this in mind when i implent the user management system in the framework.. You almost for sure do *NOT* want to attempt to send the entire Webster's 2nd Edition dictionary to the browser as JS data so that the JS can check. :-) Hehe, oh? Really? ;-) I suppose you could do a Web 2.0 Ajax-y thingie for that... Not a fan of forcing users to download/use active-x controls.. (accesibility, usability etc..) At any rate, the validation in JS may not always be exactly the same as in PHP, even if their PCRE patterns are 100% compatible, which I doubt. I'll do some experimenting with this.. For anything that really matters, your sanitation probably ought to be custom-tailored rather than off-the-rack anyway... Glad we share this opinion..

Also, this is quite easy to hack, as some browsers even support defining what referer to use.

Fw: [PHP] PHP URL issues
One more example of a questionable benchmark, not wrong but I wonder (as I was doing in my previous) whether it is really representative. There are two main ways to handle strings, one is to malloc exactly the required memory for each string and keep moving characters around from one chunk of memory to another. If you append a single character to a string, you would measure both, add their lengths plus whatever overhead your data representation requires, malloc that much memory, move the characters from each source and then free the memory occupied by the first. The other way to do it is to malloc memory in more or less fixed sizes and include in the header of your variable a length field. With plenty of memory available nowadays, few still choose the first option. Appending a few characters does not require any new memory allocation nor freeing it up. The later method depends on how good where your statistics (more damned lies once again) about the average string length, but if you get it right, appending to a string ( .= operator) becomes as fast as appending to a StreamBuffer, as found in other languages with separate Strings and Streams classes. Some languages do not even require string space to be contiguous so that when one block is used up you don't have to get a bigger one and move everything to the new place, the blocks comprising the string are linked in a list. That's one reason why lots of languages now prefer 'immutable strings', it is no longer possible to treat the string as an array of characters since they cannot be accessed via a simple offset. This benchmark is probably exercising more the symbol table lookups and memory allocation functions than the actual concatenation, since it is allocating and freeing up lots of space for really tiny strings that don't take much of that space at all. Whatever difference there is in the actual string operation might be clouded under other factors. Regardless, I do prefer to use single quotes and, as I mentioned elsewhere, I just echo the bits and pieces as soon as I am able, reasoning that the output buffer is truly a stream buffer and since the echo is a language construct (no function call overhead), it should be faster than managing memory to hold strings. As I said, though, the performance of one option against others varies so much in different trials under different conditions that I feel foolish just to show them. Then, not even logic works fine if you mean to define what is faster and what is not. Sometimes the developers, using profilers and such tools, find a very slow spot and they get to optimize it to such an extent that it works faster than its un-optimized relative, which under equal circumstances would have actually been faster. Using single quotes for PHP strings frees me the double quotes for HTML attribute values without any need to escape them. I have defined CRLF and TAB as constants which I can redefine at any time to an empty string if I no longer care my HTML output to be readable. Since I prefer to keep all values in their native PHP format up to the last moment, and those values have to be passed either through htmlentities(), number_format(), money_format() or strftotime() on output, variable interpolation is out of the question anyway.

Security is a an issue I need to learn understand further in regards to Vista and may well be the cause of my problem. And while I don't find much logic in Richard's solution (I.e., copying the DLL), without trying, it would be too premature to label it logical or illogical - because if it does work, logic can be scrutinized.

[PHP] logging erros and user access to logs
My users want to be able to debug their scripts, see mysql errors,
and such. Using mysql_error(), and display_errors, problems such as
non-existent databases, or variable and such seem to get printed to the
screen. However, syntax errors do not. They get written to the global
php log, for example, PHP Parse error: parse error, unexpected T_ECHO,
expecting ',' or ';' when a semi-colon is missing. I can't just give
all system users access to the global log.
I saw an example at
http://www.php.net/manual/en/ref.errorfunc.php#ini.display-errors that
seemed to suggest including the script to debug in something like this
demodebug.php script would do the trick:
?php
error_reporting(E_PARSE);
ini_set('display_errors','On');
ini_set('display_startup_errors','On');
include('demo.php');
?
When I remove a semi-colon from demo.php and load demodebug.php in the
browser, nothing is displayed on the screen. The error still goes to
the global log.
I'm running PHP 4.3 on Apache 2. I have these settings in my php.ini:
error_reporting = E_ALL ~E_NOTICE
display_errors = Off
display_startup_errors = Off
I thought the above debugdemo.php script was basically supposed to do a
local override so that script could display the errors.
Is there any good way to let users see all the errors from their
scripts.

Re: [PHP] Environment variables...
Well, as David BERCOT pointed out, if this is in a web environment
then the environment available to php will be that of whatever user
your web server is running as (probably 'nobody' if you're on apache,
not sure about other web servers). So, you'll need to look at making
that variable available in you're web server user's env.

You changed your html code, you have id=1, and in your PHP code you
are requesting img, so change
centerimg src=image.php?id=1 width=200 border=1 alt=/center
to
centerimg src=image.php?img=1 width=200 border=1 alt=/center
But i must also say, it is NOT safe to input data from ?img= directly
into your database, someone could do a SQL injection right away with
this code!.
He's not using image.php to insert. Earlier he mentioned using phpmyadmin to
insert the image, that was the way I used too. First learn to display an
image, this way its easier to know if any upload script you make up later is
working correctly.
Then about this piece of code
while ( $row = @mysql_fetch_array($result) )
{
$imgid = $row[id];
header(Content-Type: .$encodeddata);
echo $title;
}
I hope for you that there's only one item with this id, if not, there
would come an error again, so a while loop is not needed, and second,
now you don't define $encodeddata and $title anymore, try this piece
of code instead of the one above:
$row = @mysql_fetch_array($result);
header(Content-Type: .row['mimetype']);
echo $row['filecontents'];

php log, for example, PHP Parse error: parse error, unexpected

all system users access to the global log.
I saw an example at
http://www.php.net/manual/en/ref.errorfunc.php#ini.display-errors that
seemed to suggest including the script to debug in something like this
demodebug.php script would do the trick:
?php
error_reporting(E_PARSE);
ini_set('display_errors','On');
ini_set('display_startup_errors','On');
include('demo.php');
?
When I remove a semi-colon from demo.php and load demodebug.php in the
browser, nothing is displayed on the screen. The error still goes to
the global log.
I'm running PHP 4.3 on Apache 2. I have these settings in my
php.ini:
error_reporting = E_ALL ~E_NOTICE
display_errors = Off
display_startup_errors = Off
I thought the above debugdemo.php script was basically supposed to do
a
local override so that script could display the errors.
Is there any good way to let users see all the errors from their
scripts.

PHP runs as its own user in its own environment.
Stuff you cram into your environment has no effect on that, as it
should be.
If you alter the environment of the PHP user you might get what you want.
You may also be able to use http://php.net/setenv
And http://php.net/getenv is probably faster than your exec.
Setting the env up in httpd.conf and/or php.ini and/or .htaccess
should work. httpd.conf for sure, others I think.

What I am trying to do is pick out some info from an xml tag the is
id'd by
$m[1] ( a match from a preceding regex. This regex is only supposed to
be applied if there is an $m[1] match. This happened without the
dot (.) and forward slash escaped in the uspace=' etc ' section. I used
back slashes to see if that made a difference, it does not. I have
gotten
a little hazy on what needs to be escaped in character classes.
I have written a number of

this one is complaining about.

What is this part of the regex supposed to be doing: [a-z0-9-\.\/] ?
Your problem is this: 0-9-, which causes a bad range error.

[PHP] register_globals and passing variables
Ok, all I am new to PHP MySQL. (please don't let this scare you off)
I had my site hosted with Gisol.com and due to their very poor service and
tech support I left them for Lunarpages.com who so far have a better service
and their tech support is excellent!! But my pages won't pass variables any
more.
When I started I purchased two books MySQL and PHP MySQL both published by
O'Riely. So far the are excellent help and instructors. I wote some pages
where I track users and their characters from an on-line game called World
of Warcraft.
On the Gisol server they were working EXCELLENT!!
Once I moved to Lunarpages, the pages load ok but they don't pass the
variables from one page to another.
The below code queries the db and list's the user's in a table, and has a
hyperlink to the right of each, on Gisol I could click the link and it would
load the view_char.php page and it listed their character and the info i
needed, and gave options to delete and edit. Again it was working
beautifully.
VIEW USERS PAGE CODE:
$sql=SELECT f_name, l_name, char_id, char_name, char_level FROM t_char,
t_users where t_users.user_id = t_char.user_link ORDER BY char_name ASC;

Possibly have it in the wrong place??

now all this does is produce a blank page... used to work great!

used this code to test the page w/o the $charid string and it works FINE!!
$result=mysql_query( $sql );
if (!$result)
{
die(Could not query the database: br /.mysql_error());
}
I wrote a help ticket to Lunarpages where I am now hosted and asked them to
set the register_globals to ON thinking this was the problem based on what
I've read and the wrote back and told me that they use suPHP to parse php
files and I have the option of using custom php.ini files. That I could
create a .htaccess file or put individual php.ini files in the folder that
contains the files im running. In other words do it myself.
So I created this file:
[PHP]
register_globals = on
named it php.ini and dropped it in the folder with all of my files.
It didn't help any.
So I added this line to the first file
include ('php.ini');
all it does is add :[PHP] register_globals = on as text at the top of my
page now.
At this point im lost!! I don't know what to do to get my A

[PHP] re regex error
Hello again; Regarding the error I was inquiring about: Warning: ereg() [function.ereg]: REG_ERANGE in path info_proc.php on line 81 I still would like to know what it means but I solved the script problem. I found that since $groups is a string that was exploded to form the $g_list array it may have been struggling to try and crawl back through the whole string in the middle of the for loop. But I don't know, because I don't know what REG_ERANGE means. I should have not been trying to run this regex at this stage of the script and, in fact (I have been doing a lot of complex programming on this project ) I had the same regex further down the list where is should have been and was already. Anyhow, I think this may be valuable for anyone who is trying to learn by watching and reading this list. thanks Jeff K -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] register_globals and passing variables
Hi Jeff,
You want to leave register_globals OFF. Depending on how $charid is passed,
you want to use $_POST or $_GET:
$charid = $_POST['charid'];
or
$charid = $_GET['charid'];
I think you'll need to do the same for your $db_select variable. Is that what
you're after?

You *could* create a file named .htaccess and put this in it: php_value register_globals on and your scripts will work as-is. It would be INFINITELY BETTER to fix up the scripts so that instead of using just $charid in the query, you would do like this at the tip-top: $charid = mysql_real_escape_string($_GET['charid']); This will take care of the register globals and it will keep you safe from SQL-injection attack. At the moment, if you turn on register_globals, it will work, but it's very very very un-safe without the MySQL escaping anyway, so you might as well fix both at once. -- Some people have a gift link here.

You used to have the - after the 9 at the end, and then you tacked on
the \. and \/ after that, and now PCRE is trying to use the - as if it
were a range-specifier, like, a-z or 0-9, only you've got,
essentially, a-z0-9-.
This makes no sense at all, as it sort of means 'a to z' or '0 to 9'
or, umm, '9 to .' or something like that, only not.
Move the - to the END of the pattern, right after the \/
PS
Technically, \ is a special character inside of quotes in PHP, as well
as an escape character for PCRE, so you really should use \\. and \\/

Re: [PHP] register_globals and passing variables
Firstly, welcome to PHP. :-)
Secondly, that's not how you would enable register_globals if they're not
enabled.
Thirdly, you do not want to turn on register_globals. register globals are a
security risk. They're disabled by default on any recent (within the past 5
years) version of PHP, although some web hosts foolishly turn them on to be
compatible with code written 8 years ago that shouldn't be used anymore. :-)
Instead, access the proper super-global to get the data you want. For
instance:
$_GET['charid']
Will have the value of the charid GET parameter passed on the URL like so:
http://example.com/index.php?charid=5
There's also $_POST['charid'], which would check just a POST request. Use
those instead of just $charid.
Also, you'll want to ensure that they're the data type you expect to avoid SQL
injection, a security risk. For instance, assuming you know the character ID
will be an integer:
$charid = (int)$_GET['charid'];
Or even better:
$charid = isset($_GET['charid']) ? (int)$_GET['charid'] : 0;
That's the ternary operator, which is useful for setting defaults in cases
where, for instance, no charid was passed at all. That way you get back a 0,
so you know you have a value and that it's an integer.
Thank you for taking PHP Security 101 in a Nutshell. :-) Cheers.

If you didn't get it, here it is again. quote You used to have the - after the 9 at the end, and then you tacked on the \. and \/ after that, and now PCRE is trying to use the - as if it were a range-specifier, like, a-z or 0-9, only you've got, essentially, a-z0-9-. quote -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
