Goto has (I believe) been described as a method of shooting yourself
in both feet at the same time.

goto (not a 'new' construct as was mentioned earlier) had its uses, but
thos would seem depricated now as you can call a function, which is
essentially what a goto did. Consider;
if('foo' == $bar){
goto(1001); //essentially a line number (remember, old school)
OR goto(LABEL); //defined constant
} else {
goto(2001);
}
Absolutely nobody in this day and age advocated goto lineNumber. The
only use to have useful advantage is goto labelName and of course
that is where the labelName exists within the current execution scope.
A function call is not an acceptable replacement since you incure the
overhead of setting up the function and the stack. Contrast the
difference in speed between is_null( $foo ) and $foo === null.
VS.
if('foo' == $bar){
assimilate($bar);
} else {
anhylate($bar);
}
Where problems arose from goto they would arise from function use as
well. Nesting goto's was every bit as challenging as properly
constructing regex statements. goto also did not fit as well with OOP
methodology, being more of a procedural construct in accordance with the
procedural programming at the time that it was conceived.
PHP has never purported to be an OOP only language. It advocates both
procedural and OOP programming methodologies. Just ask Richard Lynch :)

The speed difference is negligible though, in this day and age,
dependent upon how much hair-splitting you would care to do. You're
still setting aside a block of code which will have to be parsed and you
incur the same setup if the goto section is the same code as the
function. The overhead is introduced in the calling of the function. But
we're splitting hairs here :)

You can use str_replace to highlight the search terms.
For example, you could use the following code for each search term (this
function also accepts arrays, see http://php.net/str_replace):

Bad idea. Very bad idea.

?pseudo_code
$html = htmlbodyI want to hightlight the word body in this text.
/body/html;
$search = body;
$output = str_replace($search, b$search/b, $html);
// $output == htmlbbody/bI want to hightlight the word
bbody/b in this text. /bbody/b/html;
// see what I mean?

Good catch Rory. A regex replace would work better here.
$search = body;
$find = /\b . $search . \b/;
preg_replace ( $find, b . $search . /b, $html );
I don't think so. If I'm reading your code correctly you still have
the same problem, as I outlined above. There is no simple solution to
this. It either involves advanced regex(more advanced than my
understanding of it), or a proper parser.
?pseudo_code
function highlight_html_string($needle, $haystack);
$retval = ;
$i = 0;
while($i strlen($haystack)){
$str = get_text_between_certain_point_and_first_instance_of_($i);
$str = preg_replace(what john said above);
$str .= get_tag_text($i);
$retval .= $str;
$i += strlen($str);

[PHP] Include (evaluate) PHP/HTML code stored in a variable
Hi all, I am trying to figure out how mixed HTML and PHP code (like one might have in a normal PHP file) can be evaluated if it is stored in a variable, e.g. obtained from a database query. Unfortunately, the ``eval'' function only accepts pure PHP code which (in addition) must not have any syntax errors. My hope is that there exists a function similar to ``include(..)'' that accepts a variable containing code. Or: is there a possibility to invoke the parser of the ``include'' function to evaluate and execute mixed PHP and HTML code? Any other suggestions? Thank you! Marc. Example : = sample HTML/PHP code stored in variable $code form action=?action=?php print(FORM_ACTION); ? input name=?= INPUT_A ? type=text value=?php print(get_value(INPUT_A)); ? / input name=?= INPUT_S ? value=Submit / /form end sample HTML/PHP sample PHP code ?php // 1. build the container of a page ... // 2. access database and retrieve the content code //into $code // 3. evaluate $code, similar to include(...) ? end sample PHP code -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] problem with IE and php
PHP doesn't really have anything to do with IE or Firefox working or failing to work, it's all about the HTML that PHP generates. What does your form tag look like? That's probably more the issue than your button or anything having to do with PHP. If you have no form tag, then the browsers might be trying to figure out what you really meant to do. This could be trying to submit the form data to the current page (yourscript.php) or could be trying to submit to the default document in that folder (possibly index.htm or index.html or default.htm or something like that). If you don't have a form tag, try something like this: form action=yourscript.php method=POST input type=submit name=submit value=Commit /form Changing yourscript.php to your script name of course, and you can use either POST or GET for the method depending on what you want to do.

[PHP] problem between IE and PHP
Hi all, I'm having a little problem with the interaction between php and IE. I have two .php pages. The first contains a form with the standard submit button. However when I come to push the button, I get a ding sound (standard error sound) and it seems like the button is deactivated. However when I try with my firefox browser, everything works fine. I then created a duplicate of the page, with no php and saved it as a .html file. With internet explorer and firefox, everything worked fine. I do not understand how this can be. Is Internet Explorer treated the php differently? Any help would be greatly appreciated.

In your example $clean will only ever hold one value. In the original
the clean array can be used to hold all clean GET/POST values. Not
many forms only have one value. The most important thing to remember
though is that your array isn't really clean, it's just valid. I
believe the original point Chris was making was that you should never
trust that $_POST will only contain the values you expect it to - they
should be moved out into a clean array first for further inspection
and filtering, if anything else lingers in the $_POST array, it's most
likely been tainted.
Best regards,
Richard Davey

Also it should be noted that the b tag pair has really been depricated

Hmmm, that would solve the above specific mentioned problem. how about
something like tag body=whatever or tag whatever=body assuming
that body is the word to be highlighted.

Re: [PHP] Explanation in Shiflett's PHP Security Briefing
Thanks Richard.
I got the point Chris was making: never believe _GET/_POST and use
ctype_alnum(), mysql_real_escape_string(), htmlentities() - and I
already started :) (Thanks Chris that was great for us beginners,
already posted on few Bosnian php forums :))
My question though was is the difference in code I mentioned just a
habit of writing code or there is some more? Some security issues too?
Let's try this way: we have a case of a form for storing registrant info
in DB. After submitting we have
$_POST['name']
$_POST['address']
$_POST['city']
$_POST['state']
$_POST['zip']
$_POST['email']
$_POST['phone']
To store submitted info to DB I would (now) use following code:
$name = mysql_real_escape_string($_POST['name']);
$address = mysql_real_escape_string($_POST['address']);
$city = mysql_real_escape_string($_POST['city']);
$state = mysql_real_escape_string($_POST['state']);
$zip = mysql_real_escape_string($_POST['zip']);
$email = mysql_real_escape_string($_POST['email']);
$phone = mysql_real_escape_string($_POST['phone']);
mysql_query(insert into info values (NULL, '$name', '$address',
'$city', '$state', '$email', '$phone'));
doing the same using arrays:
$submitted = array();
$submitted['name'] = mysql_real_escape_string($_POST['name']);
$submitted['address'] = mysql_real_escape_string($_POST['address']);
$submitted['city'] = mysql_real_escape_string($_POST['city']);
$submitted['state'] = mysql_real_escape_string($_POST['state']);
$submitted['zip'] = mysql_real_escape_string($_POST['zip']);
$submitted['email'] = mysql_real_escape_string($_POST['email']);
$submitted['phone'] = mysql_real_escape_string($_POST['phone']);
mysql_query(insert into info values (NULL, $submitted['name']',
'$submitted['address']', '$submitted['city']', '$submitted['state']',
'$submitted['zip']', '$submitted['email']', '$submitted['phone']'));
Is this REALLY the same or there is a difference in security or
something else?
Thanks :)

Richard already answered this pretty well, but I wanted to mention that
this is not the only way to do things - it's just the method that I use.
The idea is that I have a single variable ($clean) that I make sure to
initialize, and because it's an array, I can store all filtered data
(and only filtered data) in it.
You could use a naming convention like $clean_username, but then you
would have numerous variables to initialize on each page, increasing the
chances of you forgetting one (although E_ALL can help you catch these
mistakes). I'm just going for the simplest approach - the easier I can
make things, the less likely I am to make a mistake. :-)
The bottom line is that you need to be able to easily and reliably
distinguish between filtered and tainted data. How you do this is up to you.
Hope that helps.

Re: [PHP] Explanation in Shiflett's PHP Security Briefing
* [EMAIL PROTECTED] [EMAIL PROTECTED] :
Thanks Richard.
I got the point Chris was making: never believe _GET/_POST and use
ctype_alnum(), mysql_real_escape_string(), htmlentities() - and I
already started :) (Thanks Chris that was great for us beginners,
already posted on few Bosnian php forums :))
My question though was is the difference in code I mentioned just a
habit of writing code or there is some more? Some security issues too?
Let's try this way: we have a case of a form for storing registrant info
in DB. After submitting we have
$_POST['name']
$_POST['address']
$_POST['city']
$_POST['state']
$_POST['zip']
$_POST['email']
$_POST['phone']
To store submitted info to DB I would (now) use following code:
$name = mysql_real_escape_string($_POST['name']);
$address = mysql_real_escape_string($_POST['address']);
$city = mysql_real_escape_string($_POST['city']);
$state = mysql_real_escape_string($_POST['state']);
$zip = mysql_real_escape_string($_POST['zip']);
$email = mysql_real_escape_string($_POST['email']);
$phone = mysql_real_escape_string($_POST['phone']);
mysql_query(insert into info values (NULL, '$name', '$address',
'$city', '$state', '$email', '$phone'));
doing the same using arrays:
$submitted = array();
$submitted['name'] = mysql_real_escape_string($_POST['name']);
$submitted['address'] = mysql_real_escape_string($_POST['address']);
$submitted['city'] = mysql_real_escape_string($_POST['city']);
$submitted['state'] = mysql_real_escape_string($_POST['state']);
$submitted['zip'] = mysql_real_escape_string($_POST['zip']);
$submitted['email'] = mysql_real_escape_string($_POST['email']);
$submitted['phone'] = mysql_real_escape_string($_POST['phone']);
mysql_query(insert into info values (NULL, $submitted['name']',
'$submitted['address']', '$submitted['city']', '$submitted['state']',
'$submitted['zip']', '$submitted['email']', '$submitted['phone']'));
Is this REALLY the same or there is a difference in security or
something else?
Not the same, not necessarily secure, and it could cause issues for your
database and/or reporting.
What Chris Shifflet is getting at in his security columns is that simply
escaping your data before throwing it in the DB is not a good practice.
This is true from both a security standpoint as well as a database
management standpoint.
While the above would prevent most SQL injections, it could still wreak
havoc with your database. For instance, what if your 'phone' or 'zip'
fields in your database are integer fields, and text gets passed from
the form? (answer: a failed DB call) Or you get a string of random
characters for the email? do you really want that in your DB?
It's easy to get lazy about this stuff, especially when it's just a
hobby or for something non-critical, but if you get into bad habits,
what happens when you're doing this for a business critical application?
(I know this one -- my DBA starts beating me over the head with a bat
for f***ing up his data, which will now take him several days to fix; I
get fired from my job because a script I wrote allowed a hacker to
delete all our customer data; etc.)
Regarding your original question, the reason Chris S. keeps things in an
array is so that all CLEAN (i.e. valid and/or secure) data is marked as
such in a single place. Additionally, it allows you to do things like
validating your $_POST array by looping over it:
$clean = array();
foreach ($_POST as $key = $val) {
$ok = false;
switch ($key) {
case 'name':
if (ctype_alnum($val)) {
$ok = true;
}
break;
case 'address':
if (preg_match('/^[ a-z0-9.\'\#-]+$/', $val)) {
$ok = true;
}
break;
// etc.
}
if ($ok) {
$clean[$key] = $val;
}
}

In your example $clean will only ever hold one value. In the original
the clean array can be used to hold all clean GET/POST values. Not
many forms only have one value. The most important thing to remember
though is that your array isn't really clean, it's just valid. I
believe the original point Chris was making was that you should never
trust that $_POST will only contain the values you expect it to - they
should be moved out into a clean array first for further inspection
and filtering, if anything else lingers in the $_POST array, it's most

You're welcome. :-)
I must point out that the functions you just mentioned fall into two
separate categories.
Filtering:
ctype_alnum
Escaping:
htmlentities()
mysql_real_escape_string()
My question though was is the difference in code I mentioned just a
habit of writing code or there is some more? Some security issues too?
Well, the discipline of web application security involves both practical
and theoretical aspects. For example, the following two code snippets
are not equal:
?php
if (ctype_alnum($_POST['username'])
{
$_POST['username'] = htmlentities($_POST['username']);
echo pHi, {$_POST['username']}!/p;
}
?
?php
$clean = array();
$html = array();
if (ctype_alnum($_POST['username']))
{
$clean['username'] = $_POST['username'];
$html['username'] = htmlentities($clean['username']);
echo pHi, {$html['username']}!/p;
}
?
They both do the exact same thing - they welcome a user according to the
username provided in a POST request. The difference is not a technical
one - it's a difference in theory.
By storing only filtered data in $clean, and by storing only filtered
data that has also been escaped for use in HTML in $html, I know that I
can safely send the value of any element within the $html array to the
client (browser).
This difference is hard to appreciate with such a simplistic example,
especially when the code is not spread out, but it mitigates the damage
that can be done when a developer makes a mistake. The worst-case
scenario is that $html['username'] does not exist - this is better than
it being tainted (both can be caused by the same mistake).
A developer can always output $_POST['username'] raw, but the idea is
that you can modify your approach to make things as easy as possible for
the security-conscious developers.
(This idea is also why I never recommend storing filtered data back into
$_POST - you want to foster the natural suspicion that developers have
for data stored therein, not deteriorate it.)
Let's try this way: we have a case of a form for storing registrant info
in DB. After submitting we have
$_POST['name']
$_POST['address']
$_POST['city']
$_POST['state']
$_POST['zip']
$_POST['email']
$_POST['phone']
To store submitted info to DB I would (now) use following code:
$name = mysql_real_escape_string($_POST['name']);
$address = mysql_real_escape_string($_POST['address']);
$city = mysql_real_escape_string($_POST['city']);
$state = mysql_real_escape_string($_POST['state']);
$zip = mysql_real_escape_string($_POST['zip']);
$email = mysql_real_escape_string($_POST['email']);
$phone = mysql_real_escape_string($_POST['phone']);
mysql_query(insert into info values (NULL, '$name', '$address',
'$city', '$state', '$email', '$phone'));
You forgot to filter your input. Shame! :-)
Escaping alone can save you in many cases, but always filter input and
escape output.
Hope that helps.

You could then pay for the license of libpdf to have PDI which lets you smush a bunch of PDFs into one big monster PDF. This is not gonna be cheap... And I don't promise Excel and Powerpoint. There are some less expensive tools on Windows (and maybe other platforms) that let you Print to PDF and you could maybe get a Windows box to use do those... Well, you could get it to do as well as you can get a Windows box to do anything at all... But the combining part will almost for sure cost you some money. I don't have hard prices to quote you, but you can dig them out. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Telling users and machines apart
On Tue, June 7, 2005 5:39 am, Merlin said: I am getting more and more emails through my webforms submited by bots. It looks like some sites liky yahoo are placing an image into their forms and the human has to enter a code visible on the image to submit the form. After some googling I found captcha, but I do not like the images. Do you know if there is a class available for PHP which does create the image and does parts of the handling? That seems like a common task to me. Maybe someone else already implemented such thing and can recommend. One of my clients was getting a zillion guestbook entries by weblink farm jerks. I could have installed CAPTCHA, I guess, but, honestly, I have a REALLY hard time as a user guessing what all the letters are with all the background noise they use -- I end up having to submit a form 3 times to get a usable image. Ugh. Not a pleasant user experience. Course, I never read the docs, so maybe that's a feature I could turn off... Plus, I couldn't think of the name of CAPTCHA (again) so it would have taken me longer to find that name than to just roll my own... Anyway, I figured I could whip up my own crude not-CAPTCHA, and be able to more easily support it, and so I did. And now I've turned it into an example for you: http://voodookings.net/eyesonly_example.htm NOTE: This wasn't intended to be released code. It's very crude, one-off, for a starving musician client that pays me $35/month, of which $20 goes to hosting fees... Buy his CD if you like old-school bluesy/roots rock, so he can afford to pay me more, and maybe I'll clean up the code :-) http://cdbaby.com/voodookings2 PS Yes, a spammer *COULD* use OCR to read that text in the image to be able to continue spamming our guestbook... Doesn't seem likely, eh? If they do, I'll add noise to the image with GD, or just switch to CAPTCHA.

Re: [PHP] Objects and Performance
Greg Donald wrote: On 6/8/05, NSK [EMAIL PROTECTED] wrote: Hi, I am creating a small API in PHP, i.e. a collection of reusable functions for other programmers. As it is now, it is just many functions together in the same file. Do you think I should make it object-oriented? What are the pros and cons of this approach in PHP? I am particularly very concerned about performance. Are object methods slower than functions in php? Definitely not scientific but have a look: http://destiney.com/Benchmarks If you want to compare object methods versus functions, you should compare identical code inside a method to code inside a function. Greg's benchmarks compare two different ideological code structures. Quite honestly, the wrapping of mt_srand() inside a function or method does not satisfy the definition of good coding, object-oriented or otherwise. Functions/methods should be used to abstract common operations. mt_srand() already does this necessary abstraction, and putting a further wrapper around it makes no sense. Nobody can give you a good answer to your question without seeing the specific code. If your code requires a lot of global variables in order to operate, you might consider abstracting this into a class. Also, if you find yourself creating several copies of the same variables, use classes in order to allow two incarnations of the code to exist in the same file as objects. If your code does simple operations on a few operands and returns a value, like our mt_srand() function, there is absolutely no point in making it more complicated. However, you could consider wrapping the functions inside a class and using them as static methods. This would essentially give them a namespace that would allow any conflicts with other programmer's function names to be more easily resolved. In other words, renaming a class is a whole lot simpler than renaming a function (think search-and-replace ClassName:: versus functionprefix_ - the second one might inadvertantly replace variables, etc., but the first is unusual syntax) So, in short, analyze the problems your code solves, and see if they would be better solved by abstracting into classes, or by keeping the code as functions. Forget about minor performance differences from program syntax unless you're writing code for a site with thousands of hits per second. In that case, you'll want to use a profiler like APD to find the real bottlenecks in your code. Otherwise your main inefficiency is going to be programmer time rather than processor time: make the code readable and maintainable and it will cut down on bugs and work better than faster code.

[PHP] Converting a query for use in a form
Hi everyone, I hope you can all help me. I want to take the information I get from a query and use it is a form as a dropdown select box. For example I want to pull the colors from a table and list them in a drop down box and then when a user selects a color it will pass the colorID for use in writing to another table. I hope that comes across the way I mean. :-( Anyway, I think I used to use something called wddx with java to do this when I was coding in ColdFusion. Thanks!! Kevin Rose Valley Soaps
