To be honest, if a client upped and move an application I'd built to an entirely different host, without consulting me prior to the move, I'd place the blame ball firmly in their court. I've never signed a contract yet that said "this code will work anywhere you dump it", and I never will. However, I understand what you're saying, and I agree with it completely. I use long tags for all full app developments, and short-tags for all prototypes. My only point is that when two options are identical in nature, there is no "best preference", only that which is the best for you, and your immediate needs. If your host doesn't support them, that's a pretty immediate need. If your client likes to up and move stuff around without telling you, that's quite a need too. If you had the luxury of building the entire site from scratch, then it's your issue. However if your client wants maintenance on a 3 year old app, spread across hundreds of files, with thousands of lines of inter-mingled short-tagged code -- well, that's a slightly different concern, and "best practises" don't always apply. It ain't never black or white!

There is no "right" or "wrong" for this, it's down to personal developer preference. Nothing more, nothing less. It's only "right" if you're building an app for distribution to unknown end-users.

file_get_contents does exactly that - it gets the contents of the file
*without* parsing it, i.e. any raw PHP code that exists within it,
will be treated as what it is when 'got' = plain text.

On the surface it looks fine, so I would echo out your query and then
paste it into MySQL (phpmyamin, SQLyog, etc) and check it works!
Or you could capture the result of the query and check for an error.
If there isn't one, it's probably a table design issue.

I need to find the number of socks in my washing basket. Does PHP have an inbuilt function to do it? No, of course it doesn't. Just because PHP can be used to script apps for web sites, it doesn't mean it has any actual concept of what a web page is, any more than it knows what a sock is.

I'm > looking for some guidlines on ensuring that my site is secure from > malicious hackers. The security of the application will be ultimately down to two factors: you, and your hosting environment. Server security is beyond the scope of this mailing list, and is a multi-faceted and complex area. Shoring up your OS, Apache and the likes can take years of skill. Or of course, your sys admin / web host does this all for you. Even so, it's an area not to be ignored. You can write the most secure application in the world, but if you've gone and chmod 777'd your directories on a shared box, you're anyones target. The security of your application is down to you however. There is a PHP security mailing list, but it's more for announcements than discussion. As for guidelines there are many free on-line resources, and you'd do worse than to start here: http://phpsec.org/library/ The majority of those documents are aimed at experienced PHP developers however. And the majority of blatant security holes come from the inexperienced who weren't aware of what they were doing wrong in the first place. There are several books available on the subject now, any (or all) of them would give you the grounding you need to know BEFORE you start coding: Pro PHP Security by Snyder & Southwell (Apress) php architect's Guide to PHP Security by Ilia Alshanetsky (Nanobooks) Essential PHP Security by Chris Shiflett (O'Reilly) Also some on-line talks: http://brainbulb.com/talks php architect magazine has a security column each month as well (www.phparch.com) There's a lot of reading material out there. Just make sure you read it _before_ you start building, it'll save you days, if not weeks, of code changes.

How about some good logistical reasons? php.net does not exist in any one location. It does not serve any one language. There are over 100 mirror sites across the entire world handling php.net, from Thailand to South Africa. The site is offered in 30+ different languages, English, Chinese, Swedish, Japanese, etc. To be true to the php project, if it were to start a forum it would have to be mirrored across all of these servers, unless you're advocating country elitism for this forum? (and no, it is not fair to force users in say Africa to have to connect to a US server). There is NO off the shelf forum software that can cope with a distributed forum in this manner, with content and user repositories spread across so many diverse networks. When you post a message on a US server, how long before it should appear on the Slovenia mirror? If it's not instant, it is less useful than the mailing list. So unless this forum syncs across the 100+ mirrors on an application level, you're left with a hardware level link-up (duplication of the database perhaps, whatever). Eitherway it's quite some work, not to mention expense, especially to keep it real-time. The reason the mailing list *works* is that the content is delivered to the people, the people don't have to seek it out. For those in relatively low-bandwidth countries they get to choose which messages they want prior to actually downloading them (most mailing packages offer a read-headers option). So if you want a "hosted in one country / location" PHP forum there are plenty out there already, I can think of 4 in my bookmarks alone. I can't think of any that will give you replies from some of the most talented php developers in the world though. If you want one that truly offers what the mailing list provides already - you're going to have to write it, because it doesn't exist.

How large was the image? Could it be that the script is timing out
during an upload? I recently had to change the max_input_time value on
one site because the uploads were so large they kept timing the script
out, yet some people (on really fast connections) could upload just
fine.

Have only done this once, but I didn't compile the DLL into PHP because that would have meant updating the php build every time a new DLL was released, and updating the functions / documentation accordingly. The DLL was built specifically with a COM interface which I accessed using the PHP COM functions (as I'm sure you've seen already). The DLL authors had to rejig their original code a little, but it was a far less painful process than compiling the DLL into PHP. However for the next revision we are likely to move the DLL code into the .NET framework, build a SOAP interface to it (C#) and let PHP talk to it that way.

How many are there? I don't use functions in that way, but I do a similar thing for class files (minus that "definedfucntions" part of course). You could of course combine them all together, and yes it *would* be faster for the script to execute as there is far less drive activity going on. But then it's a trade-off between maintaining that single massive file, as opposed to updating smaller chunks. If it's a real issue looking at something like Zend Encoder would help.

You could try using file_get_contents instead of fopen/fread/fclose
and see if that makes any difference.
Also possibly try stat instead of filemtime? It would at least cache
the file stats on the 2nd run through, etc.
At the end of the day though any hard drive operation is going to be
relatively slow. Perhaps there is another way to do what you need that
avoids opening all the files? At the moment you appear to be checking
every files modified time then opening it. Perhaps you could get back
a directory listing instead and parse the modified time from this,
rather than check every single file?

And there are > ways of avoding unnecessary BC maintenance altogether. Beyond not staying stuck in the past? Not really. You either code for PHP4 or you code for 5. If you're really lucky (or just write really basic scripts) then your code will run on both. If your host doesn't support 5, they need to wake-up and smell the roses. Introducing a tag is the wrong way to address it, never mind being at the wrong end of the pipeline. If you want to control support from a code point of view, it's not difficult to detect which version of PHP your running under. But allowing for that through your entire codebase is just a tad more work, to say the least. Backwards compatibility doesn't slow down the evolution of a language - having no users slows down the evolution of a language. And if PHP was to totally change its language structure on every new version, I can't think of too many people that would continue using it. The changes from 4 to 5 are significant, but not overwhelmingly so. I envisage that change from 5 to 6 will be significantly less of a jump.

Start with the obvious - what actually IS the value of
$discountResult["dateexpired"]? var_dump it out and have a look. Check
you are comparing like with like. You're also not performing a strict
comparison, so string conversion could be going on here.
The other obvious fact is that if dateexpired is less than *right

Forget trying to include style elements in the header block for emails, most mail clients strip them out totally. There is no foolproof way to embedded CSS into an email and have all clients handle it correctly (if at all). Lots of mail clients will attempt to render the HTML themselves and don't support any form of CSS at all, whereas others (like Outlook) use the IE rendering engine on Windows. My suggestion? Embed the font styles into the email body and don't even bother with a section. I'd even go so far as to suggest you use the HTML 4.x tags instead of CSS.

While you can call shutdown directly from exec - some things are best
not called like this. PHP will be left hanging waiting for the process
to finish, so you'll get a really nasty shutdown going on without
properly ending your sessions.
You'd be better off looking at COM scripting it to be honest. Or write
a Windows application that does what you require (closes down all
services smoothly, reboots, etc) and exec that, providing your IIS
user has the correct permissions to do so.
The warning most likely comes from IIS, or your php.ini settings - I
just tested "shutdown -i" on Apache (in WinXP) and it ran without any
problems.

You're not doing an un-checked include - it's definitely checked.
You've pre-defined the $includepath at the start of your script, so
no-one can over-write this. You've forced $header to be one of the
switch options and *nothing* else. So those two things are certainly
clean.
If someone manages to inject bogus variables into your
$_SERVER['HTTP_HOST'] element then you've got bigger things to worry
about than your code :) (i.e. someone has compromised your server) but
with your switch block and pre-set values even if they had managed
that, you'd still only ever include a valid header.
You have to draw the line somewhere with security - nothing will ever
be 100% safe because there are so many chains in the loop (firewall,
network, server, apache, php, etc). I would say that as it stands
you've done the best you can for this little section of code, but
perhaps some others might post more ideas if they have them.

$_SERVER is, thankfully, _mostly_ populated by the web server, not the
client. HTTP_HOST certainly falls into this category. The only thing
you probably shouldn't do is rely on it always being there, so have
some catch-all set of headers / css if it's not set (mind you, if that
happens you've got a bigger problem on your hands! but it'd stop your
site breaking).

Why are you creating lots of arrays and then using in_array to check
them? Just seems a little pointless in this instance as it gives you
no real benefit - comparing a one element array against a variable is
just... well.. comparing a variable with a variable! So why not do
that? Perhaps a switch block would serve your needs better?
switch ($_SERVER['HTTP_HOST'])
{
case 'name1.host.com':
$header = ..
break;
}
etc - then you can combine multiple hosts into one section and have a
default set at the bottom.

Re: [PHP] parallel execution of php code?

You're doing a loose type comparison between $rows and zero (== rather than ===), because it's a loose comparison a number of different results could equal zero in this case. For example if execute() returned false your code would assume an insert is required, which might not be the case. If you're using MySQL then you may want to look at using a different method for checking / inserting this data. Rather than a SELECT followed by INSERT you could use an INSERT IGNORE which won't duplicate data if it already exists. Or possibly REPLACE INTO - depends how you need this to work (i.e. retain the oldest copy of the data, or keep the newest). Look in the MySQL manual for those two functions for more info.

It will ignore it totally, it doesn't even make it as far as the log files - which is why in most cases it's a bad thing to use.

AM> And what if the user closes the browser window? :) All of those things are unavoidable no matter what technique you use :) I've seen multi-page forms with a "Finish this later" option that issues a cookie to your browser, allowing you to visit the site at any (realistic) point in the future and carry on. In which cases the part-filled contents must already be in a database somewhere. This isn't a bad thing imho, it's a nice touch. Of course it's prone to the usual "browser doesn't accept cookies / browser deletes cookies" syndrome though. If you don't want to pass the form values across in a hidden manner (and I don't blame you) then it's either dump it all in a session and hope it doesn't time-out, or dump it into a database, issue the visitor some link to that entry (cookie, session var) and again hope they don't time out. The only real difference being the DB option will need purging to get rid of incomplete forms > X days old. But that in itself could prove a useful statistic for reports. Unless you're dealing with thousands of sign-ups an hour, I don't see any issue with this option. Another technique might be the following - rethink how your forms work. Exactly what is it you're collecting data about? If it's part of a long sign-up process then you could consider changing the process around a bit - so that the VERY first thing the user does is create a temporary account on your site (call them "incomplete users"). So you grab some method of login + authentication details from them. Then the form pages following this can all be saved to a DB and linked to that user. So, as long as they complete this first step, they can always come back and finish the job off - whenever they want, avoiding cookie and session time-out issues. This won't work for all forms of course, it depends what the nature of the process is, but it's certainly an option.

If the width is greater than the height you're calling CR_make_crop which has this line: imagecopyresized ($new, $img, 0, 0, 0, 0, 90,120,$width_orig2,$height_orig2); The problem is that what you're effectively saying is: Copy the entire original picture (0,0 to $width_orig2, $height_orig2) into an area 90x120, and resize it when you do it. That's not a crop :) That's a resize. You'd be better off with a function like imagecopy() instead - once you have that 90x120 cropped piece, then you can do whatever it is you wanted to do with it.

If the user misses out the closing [/i] tag then when it comes to parse the BBcode into HTML it'd never happen. All decent BBcode parsers search for both pairs of tag.

I haven't seen one that did a straight str_replace for a long time now (although I guess they still exist! and in those cases I agree with you, they are pointless and utterly insecure). If you allow direct HTML as user input, you HAVE to check and validate every single aspect of their HTML for all possible errors, typos, included XSS attacks, etc - and if you fail in even one of these checks, they can break the layout of your site, or worse. Whereas with BBcode the worst that can happen (in this instance) is that the user looks like an idiot because [i] tags are left in their input. Another benefit IMHO is that you control what [i] gets turned into, for example I don't use tags in my HTML as I don't believe they are semantically descriptive.

Re[4]: [PHP] IBM's Learning PHP Part 1 tutorial.

Once it's in memory at the other end, sure they'll both most likely become longs anyway. As for the query itself, MySQL could use its query cache on either and both would require the same analysis of the index/table to obtain their end result due to the where clause.

From MySQLs point of view num_rows is calculated and returned to PHP irrespective of which method you use. You could mysql_num_rows it and then PHP will have to perform a zend fetch resource, doing an index look-up on the hash (and returning the result). Or if you've count'ed it, it'll have to return the value stored via a mysql_result call (or similar), which takes a few more trips around the hash table. When it comes down to milliseconds, I doubt there is much in it to be honest. Certainly something hard (and I'm sure you'd agree useless) to quantify. But hey, we're being pedantic here, yes? :) At the end of the day it just seems like a coding preference to me. After all, I don't want the users ID number, I want to know how many users exist matching that username (i.e. I want a count of them), so that's what I've directly asked MySQL for. A "one cat, 1 billion skinning combinations" scenario again I feel. Best regards, Richard Davey -- http://www.launchcode.co.uk - PHP Development Services "I do not fear computers.

To be honest that is quite shocking code, especially from a "teaching
beginners" perspective - and even more so coming from the likes of
IBM. But, SQL injection issues aside, the problem is most likely that
there is nothing wrong with your SQL query. mysql_query will return a
false (for a SELECT query) only if there is an error, not if "no
records exist" - that isn't an error.
It would make more sense to actually do a: "SELECT COUNT(*) AS hits FROM
users WHERE username = 'x'" and then check the value of the returned
"hits" (which will always return something, even if zero).
Alternatively instead of doing if (!$result) you could do: if
(mysql_num_rows($result) > 0) ... that way you know that the user
already exists.

Richard Davey

It looks to me like the \n (linefeed) character is actually being

a line-feed, etc. I may be wrong, but I don't think MySQL likes this,
and given the error you are receiving it looks like that might be the
case. Quote it with ' ' to avoid translation of the \n and \t.

I only read the PDF version of php|a, which is much cheaper and lets me print out only the pages I want to scribble notes on. php mag is nicely laid out and the content quality is as high as php|a, but it's pretty expensive. Why not just buy a couple of issues of each and see which you prefer? On the topic of PHP Magazines, they are maturing quite a lot but still suffer badly from coming across more as a collection of un-related articles written by developers about their latest projects. Because all the contributions come in from across the world, there's very little consistency either in writing style or theme of content each issue, and sometimes authors whose native language isn't English create works that are harder to read. They're both a great read and I appreciate nearly all of the articles in them, and the people who've spent the time writing them. The disjointed nature of the content isn't the authors fault, it's just the way they are edited at the moment. Regular columns (such as Security Corner in php|a or Guru Speak in php-mag) are helping to address this, but what you won't find in them are all the authors working together to address a specific topic. For example in most development magazines I read they'll often have a theme for the issue, i.e. security, and then the articles will be centered around that theme from differing levels of complexity and scope. I am sure the current crop of PHP magazines will migrate towards something more coherent in structure as time goes on (and their circulations increase), rather than feeling like a grab-bag of non-specific PHP goodies as they do today.

PHP can not run in a J2EE environment, limiting AS> it to small scall websites and limiting the prospect of expansion AS> or server migration. You like to tout CF as being J2EE/Enterprise ready. For this the free version of Blue Dragon is NOT suitable, by the developers own admission. You need the $6000 Enterprise version of CF (and you can add on a few more thousand $ for extended support). This is before you've bought any of the extra components you need to finish your application. 1) Blue Dragon is also not just a "free" version of CF it would appear, even on the developers web site they describe the free version as "Functionality is robust and useful for most basic CFML applications." - it's the words "most basic" that concern me here. 2) It doesn't support the newer CF 7 features. 3) The free version does not deploy into J2EE at all. 4) It only runs on Windows, OS X or Linux (sorry, but lots of very big hosting companies prefer the stability of FreeBSD, Solaris, etc). If you want Solaris support it costs $2499 per CPU. If you want FreeBSD support, you're stuffed. 5) It only supports ODBC database connections (via JDBC), so unlike PHP you won't be connecting to Oracle, MS SQL, SQLite, etc. MySQL is supported, but not built-in. If you want to do CF seriously, you need to invest thousands and that's before you've paid your programmers - this is the bottom line. Perhaps that is why even the Blue Dragon developers themselves claim its biggest advantage is: "You've invested heavily in CFML.. so have we. Protect your investments." - and how do you protect them? by deploying Blue Dragon so you can then interface directly with .NET applications rather than migrate totally to them. This doesn't strike me as being the approach of a growing, competitive well supported language. It sounds more like "shit, people have woken up to the massive cost of using CF, how can we slow the drop-out rate?" if that is Blue Dragons primary selling angle, it says a *lot* about the state of serious CF development. When it comes to investing it think long-term. Zend are aggressively attacking the enterprise market and we will see more and more movement in this direction, to the point where I am quite sure their objective is to make PHP itself enterprise capable *regardless* of J2EE. With the rate things change around here, we won't have to wait too long. If you don't actually need to build an enterprise scale site (and let's face it, that covers most of us) then you're good to go with PHP *right now* without actually spending a dime. Take that $6000 CF budget, invest it into training for your entire team and build your own framework, with the knowledge that no matter what happens, your work is safe. Anyway, time to get back to my project for BMW - just one of those "small scall websites" (sic) things I guess?

(Disclaimer: I am NOT a Unix expert, this is just what I've picked up over the years, perhaps it doesn't even apply any more? Hopefully someone else can follow this post up and clarify) AFAIK each file is assigned an inode. Some filesystems have inode limitations - meaning you can run out of them if you have too many files on a partition. You can use "df -i" to show this information, right not it's probably nothing to worry about - over time as a site gains popularity it can be. You can run out of inodes before you run out of disk space (depending on the average size of your files). Creating extra partitions helps avoid this, as does using an "extent" based filesystem. A filesystem with "journaling" also helps should the server ever crash as it caches disk information and won't need to spend ages doing a massive re-built when the server boots again, which depending on the number of files can take hours. ReiserFS / XFS are good alternative filesystems, but again refer to my original disclaimer - there may be better options these days.
