RE: [PHP] Dear Lazy Web: Pseudo Randomisation Strategies on Listing Websites
Hi Col, Interesting problem. Are there any other approaches I've missed? Off the top of my head, how about this: 1. Add a new unsigned int column called SortOrder to the table of widgets or whatever it is you're listing 2. Fill this column with randomly-generated numbers between 0 and whatever the unsigned int max is (can't remember exactly but 4.2 billion ish) 3. Add the SortOrder column to the end of all your ORDER BY clauses - SELECT foo ORDER BY TypeOfListing, SortOrder will give you widgets sorted by Gold/Silver/Bronze type, but in a random order for each type 4. Every hour/day/week/whatever, update this column with different random numbers Advantages: practically no hassle/overhead/maintenance for you; provides same ordering sequence for all users at the same time; only breaks third one down-type references when you refresh the SortOrder column rather than on each session or page view; reasonably proxy- and cache-friendly especially if you send a meaningful HTTP Expires header. Disadvantages: breaks user persistence if they visit before and after a SortOrder refresh (I'm sure the one I wanted was at the top of the list yesterday...); more effort to demonstrate randomness to the client (OK, see how you're in ninety-third place today? Well, check again tomorrow and you should be somewhere else on the list). Hopefully food for thought anyway.

Re: [PHP] register_globals security
Hi Fernando, I have a PHP application that passes variables (values) from a form. I get these using $_POST However I do also post some variables via a link. Which ofcourse requires register_globals to be ON. Do you mean variables in a URL, like this: www.example.com/index.php?foo=1bar=2 If so you can access these via the $_GET array and leave register_globals turned off.

Re: [PHP] PHP Editor - which to use?
Hi,
Good coder will understand this at a glimpse:
[snip horrible code]
if($pos_params!=false)
Assuming it's a boolean, $pos_params is *already* true or false, so testing
it like this is pretty much pointless. It makes more sense (and is much more
readable IMHO) to do something like this:
if ($pos_params) {
// something
}
I'm not sure how the PHP interpreter works internally but that might even
save your script the overhead of an unnecessary comparison ;-)

Re: [PHP] Training Help
Hi Ryan, Sounds like register_globals is turned off on your server (this is generally a Good Thing). Rather than having all your form fields converted directly into variables - which your book is assuming, as it's how PHP used to do it - you'll need to access them via the $_POST array. Try changing this line: echo $tireqty. tiresbr; To this: echo $_POST[tireqty]. tiresbr; Search the manual or the list archives for register_globals and you'll get loads of info about this.

Re: [PHP] Training Help
Hi Ryan, $tireqty = $_POST['tireqty']; $oilqty = $_POST['oilqty']; $sparkqty = $_POST['sparkqty']; That'll certainly fix the problem, but it kind of defeats the point of using $_POST :-) Ideally you'd clean the data at this point to make sure no-one's trying to submit anything nasty (Google on SQL injection for an idea of what can be done). Seeing as these are quantities, checking them via PHP's is_numeric() function would probably be a good idea, and making sure they're inside sensible ranges (between 0 and 50, say) might be worthwhile as well.

One way would be to have two buttons in your form, but submit to only one

form action=process.php
input type=submit name=op value=Continue
input type=submit name=op value=Stop
/form
... and then, on process.php, you decide what to do:
if ($_GET[op] == Continue) {
// do continuation stuff, or redirect somewhere
} elseif ($_GET[op] == Stop) {
// do stopping stuff, or redirect somewhere
} else {
// handle gracefully

RE: [PHP] Opinion on a method....
Hi Dan, I would like to get some opinions here on a method I'm doing to grab connect information for a mysql connection. Currently I am doing: $pinfo = fopen (/director1/directory2/filename.ini,r); Does this filename.ini contain the code to connect to your database? If so, I usually do two things with this file: 1. put it outside the document root, so users can't browse to it 2. put any code that might output something (an error message, for example) inside a function, so even if it is run, nothing will happen - you need to include() it and then call the function yourself. If it's just connection information, with no code (I'm a bit confused by the .ini extension :-) then just make sure it's somewhere outside your document root. Is XML a solution? I don't think XML is inherently any more secure than plain text - it's all down to how you store and transmit the data.

RE: [PHP] checkdate function
Hi Siva,
checkdate function verifies whether the date is valid or
not by taking month, day and year as arguments.
The problem is when someone enters a three digit year by
mistake (200 instead of 2003), this function does not catch it.
Yes, I've been bitten by this as well :-)
We are separating the year part from the string and validating
separately to solve this problem. Is there a better way to do it?
I think you're stuck with the extra validation step, but you can do it quite
neatly with a replacement function that looks something like this:
function myCheckdate ($m, $d, $y, $min = 1900, $max = 2100)
{
// check whether $y is within allowable range
if ($y = $min || $y = $max)
return false;
// the year is OK: checkdate can do its stuff
return (checkdate($m, $d, $y))
}
You can adjust the default allowable years to match what you usually need,
and then override them as necessary.
Personally I'd like to see PHP's checkdate() work a bit like the one above,
or maybe have checkReasonableDate() and checkImprobableDate(): I'm prepared
to believe that some PHP developers need to validate three- and five- digit
years, but I can't believe that it's *that* common :-)

Notice how the IP changes - they requested the page from 205.188.209.165,
and then got each of the images from a separate IP.
but it will not work when they are behind firewall.they will
be assigned same IP.is there a way for me to get the IP (e.g.

Hi Iggy, I mean the difference between having that code on every page or calling it from an external page doesn't tell me if it is realy necessary to do it all the time. Yes, you do have to connect to the database in every script that needs to access it. Usually this is done at the start of the script, along with any calls to session_start() and other global stuff. For convenience and ease of maintenance, however, it makes good sense to write a separate file that does nothing but connect to the database. This separate file then needs to be attached to the running script via include(), at any point before the first call to the database.

RE: [PHP] Preventing the hijacking of pictures
Hi, $_SERVER[HTTP_REFERRER] does not help.

RE: [PHP] date, first of next month?
Hi Bryan,
$t = mktime(0,0,0,date('m')+1,1,date('Y'));
Gives you timestamp of first day, next month.
Format accordingly with date().
is there such a say to now get the date of the first
weekday after that date?
You can brute force it:
// grab the timestamp
$t = mktime(0,0,0,date('m')+1,1,date('Y'));
// if it's a saturday or sunday, add 86400 seconds (1 day)
while (date('w',$t) == 0 || date('w',$t) == 6)
$t += 86400;
This doesn't take into account any bank holidays, of course - you'll need to
do a lookup against a database or an array if you want to test for these as
well (not sure if you want the first weekday or the first working day).
There might be a more elegant way to do this, but with a maximum of three
iterations round the while loop, I don't know if it's worth looking for :-)

RE: [PHP] Date check
Hi Fredik,
I have to dates that i want to check who is biggest.
This does not work:
if( $date1 $date2){
How can i check them?
Presumably they're in SQL format, or something similar?
The easiest way is to convert them to unix timestamps (look into the date()
and mktime() functions to see how this is done).
Timestamps are integers representing the number of seconds since 1st January
1970, so comparisons are extremely easy :-)

RE: [PHP] Dynamic input fields in Form
Hi Frank, I have a form where the user selects for example; how many cars you have: 4. Then it most dynamicly create 4 input fields [...] Using only PHP, you'll have to make this a two-step process where page 1 collects the number of cars and posts to page 2, which generates the form accordingly. If is has to be done on the same page, you'll need to call a Javascript function every time the number of cars changes. That function will have to add or remove inputs from the form depending on the number of cars entered, and of course the whole page will break completely for anyone without Javascript. I'd make it a two-step process myself, it's considerably more robust and offers considerably less room for problems (what happens if I claim I have five cars, fill out their details, and then change it to three cars? which details do you get rid of?)

Not sure you can, especially not for the just doesn't work scenario.
FWIW, you can test for the existence of a file before including it:
if (file_exists(file/to/be/included)) {
include (file/to/be/included);
} else {
include (backup/plain/HTML/file);

RE: [PHP] IFRAMES PHP
Hi Greg, But the buttons are outside of the iframe, so that no matter how large the frame gets, the buttons are always in the same place :/ So stick an image of the button outside the iframe, wrap it in an a, and use the onclick handler to call a javascript function that submits the form. Of course, this will break for anyone who doesn't have javascript enabled (some estimates put this as high as 20%, but it depends on your audience). Alternatively, put your form inside a div with a fixed height and width, and the overflow property set to scroll or auto. This should behave in much the same way as your iframe, but with everything on the same page. Again, this will break for some users (those whose browsers *cough*NN4*cough* don't support fixed positioning and overflow), but at least it degrades more gracefully than the scripted solution. Thirdly, if you provide a link to a sample page, someone might be able to come up with a way to rework your form so you can avoid all this entirely :-) Cheers Jon -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hi Kevin, I am trying to find out what the best way is to display only the first 20 or so characters of a comment. [...] I am not sure if it is best to do it with the select statement or format it with the PHP. Either way I am not sure how. If you only want the first 20 characters, and that's all you ever want, it's probably best to do it with the select statement, because then you're not spending time and bandwidth getting data you don't need from your database. SELECT LEFT(someField, 20) FROM someTable will get you the first 20 characters. Of course, you now have a problem with words splitting :-) You can get around this either by grabbing the whole comment and splitting it on spaces, or by having a separate synopsis field in your database (this is how I do it).

You could try separate drop-downs: one for day (with numbers 1-31), one for month (with names) and one for years (whatever you need). This gives you three variables that you can easily pass to checkdate().

RE: [PHP] Javascript var to PHP
Hi Cesar,
Jon, thanx for the fast response, but the problem is
that the link is made dynamically from a DB and the varvalue
changes on every link... if it helps, I make this link
list with a FOR loop in PHP and the varvalues
I want to pass are the IDs of a table elements.
You probably need to do it along these lines:
// assume ids are in $id[1...10]
for ($i = 1; $i = 10; $i++) {
echo 'a href=javascript:lauchinfopage(';
echo $id[$i];
echo ')click for more info/abr /;
}
and, in your JS function:
function launchinfopage(id)
{
url = infopage.php?id= + id;
// open url however you like
}
I imagine you have your url hardcoded in your launchinfopage() function...
this makes it less portable, you may want to consider passing the complete
url to a generic open new window function.

RE: [PHP] Filter vulger / controversial words - need word source
Hi, I think we've seen this discussion on the list before (so Christopher, check the archives!) Quite :-) The problems that others have experienced in the past are: - what happens with misspellings, e.g. fsck? - what happens with dodgy formatting, e.g f s c k? - what happens with words like Scunthorpe? Problem 1: add likely/popular mis-spellings to the list of vulger/vulgar language So when I'm giving a Linux user advice on how to recover from a disk crash, my run fsck comment will get trapped the problem here is that context is *everything*. You just can't know, by seeing the word fsck without any of the surrounding text, whether I'm swearing at another geek or helping them out :-) There will also be problems with slang and idiom - e.g. fag in .uk is a cigarette, but it's something quite different on the other side of the pond. Again, this can only be judged from the context. Finally, the more words you have in your list (to cover common misspellings), the more likely you are to get a false positive (again, context) - and you *will* cause offense if you trap someone's name, for example. Problem 2: (contrived) very few single-letter words exist so remove intervening white space prior to analysis Yup, also line breaks, dashes, asterisks, plus signs, etc etc :-) Problem 3: Scunthorpe contains an unfortunate series of letters (amongst the town's many disadvantages) however the critical four are not a word in and of their own right so employ whitespace (\s) in the RegEx or token analysis. That's a good solution, but it's something that obviously is being missed by many developers of this sort of algorithm... see the couple of followups I made immediately after my original response. May I suggest, rather than picking your way through this minefield, you provide a report abusive comment link instead? However some countries are now legislating responsibility that ISPs/employers must discharge Whoops, forgot about that...

I don't know of a PHP-based report generator (although a hunt round sourceforge might turn something up), but you can: 1. use PHP scripts to output your reports in HTML, with CSS for styling and layout 2. use a standalone reports package like Crystal Reports which will talk to MySQL directly 3. build an MS Access front-end to your MySQL tables and use its native reporting functions At $WORKPLACE we have a number of reports generated as HTML pages by PHP scripts - these are the ones that get run many times on a daily basis and always look the same - and Crystal installed on the managers' PCs for ad hoc reporting.

RE: [PHP] How do I run a command as root?
Hi Luke, I'm trying to find out how to run a command on the server as root. Does anybody know how to do this? How about using a combination of exec() and sudo (assuming you're in the sudoers file, that is)?

RE: [PHP] Newbie Question
Hi Hacook,
I have a mySQL database called srchresult in a srchresult base.
In it, i have 9 fields. Everything works perfectly.
I would like to know how can i list in a HTML table 30 results for
example
but only with 7 columns (7 fields only) ?
Try this:
?php
// open the db connection - replace these with your own settings
$db = mysql_connect([server], [username], [password]);
// select the database - replace with your own
mysql_select_db([database], $db);
// get the query - add your own field names here
$q = mysql_query(SELECT Field1, Field2, Field3 FROM srchresult LIMIT 30);
// start the table
echo table;
// loop through the results
while ($r = mysql_fetch_array($q)) {
// echo a table row
?
tr
td?=$r[Field1]?/td
td?=$r[Field2]?/td
td?=$r[Field3]?/td
/tr
?php
// end of while() loop
}
// finish the table
echo /table;
?
It's untested - shout if it doesn't work.
Cheers
Jon

RE: [PHP] Hello ! How to write a programme in PHP which executes a routine at a given time ?
Hi Jonathan, Do you mind to tell me how to make a PHP programme to execute a centian routine at a given time ? Thank you ! PHP doesn't have anything built in that'll do this for you (at least, nothing that I'm aware of). The best solution is to call your script from your OS's scheduler - cron under unix/linux, or task scheduler in Windows. I usually trigger the script with lynx and pipe it to /dev/null, but if you have PHP compiled as a standalone instead of a server module, you could call it directly.

Hi, Are you interested in this?! New generation of PHP Program, reaction to ASP.NET I saw it when you posted it yesterday and tried it out, but it didn't work for me. I imagine this is because I've disabled Javascript. Cheers Jon -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] Loooooooooonnnnnnnnnnggggggggg
Hi, I made a script that works on a very long charachter chain and its process is lnggg about 5 minutes ! Do you have any tips to make it faster ? My mysterious ninja PHP developer powers have told me that you need to fiddle with lines 23 and 72, that's where it's slowing down. IOW, it would be helpful if you could post the code for this script. Without seeing it the only thing I can suggest is you minimise the amount of string concatenations, as this is a fairly expensive operation.

RE: [PHP] something like array_walk?
Hi,
I want to take an array and get the soundex() for each element
in that array and return the results into another array.
How about:
$color = array(blue, green, orange, purple, red, yellow);
$soundex = array();
foreach ($color as $foo) {
$soundex[] = soundex($foo)
}

RE: [PHP] I'm in need of a PHP web host recommendation
Hi Phil, would like to hear some recommendations of some good companies that host PHP/MySQL and also JSP. http://34sp.com/ are great if you don't mind .uk-based hosting. I've heard good things about http://oneandone.co.uk/ but haven't used them myself. At the other end of the scale, you should stay *well* away from http://zenithtech.com/ - they're without a doubt the worst host I've ever used.

RE: [PHP] Re: How do i make an upload script?
Hi, How do i make an upload script? http://us.php.net/manual/en/features.file-upload.php ok, this is upload.php: form enctype=multipart/form-data action=upload.php method=post input type=hidden name=MAX_FILE_SIZE value=1000 Send this file: input name=userfile type=file input type=submit value=Send File /form Yup, copied and pasted from the manual page, that should work. what else do i need? 1. A script to receive the uploads 2. A file to upload The manual page you linked to above will be of use in completing stage 1 - there's a bit further down that you need to copy and paste as well. Read the user comments as well, as they will answer questions that will inevitably come up. Stage 2 - well, you're on your own, but there should be something on your hard drive that's suitable.

RE: [PHP] random numbers
Hi Tamas,
/* srand is not important since php v=4.2.0 */
$numbers = range (1,90);
$x = array_rand ($numbers, 5);
foreach ($x as $v) echo {$numbers[$v]} ;
It works fine, except the first query: php may restart
the random numbers, if it is not used for some seconds.
I'm not sure how to solve this, but I'm curious as to why you don't want to
use mt_rand:
?php
for ($i=1; $i=6; $i++)
$x[] = mt_rand(1, 90);
foreach ($x as $current)
echo $current. br /;
?
You still get an array at the end of it, which seems to be what you're
after.
Cheers
Jon

Thanks for help, but your program may generate same numbers between
the 5 generated numbers, hovewer I want to generate different numbers
such as lottery-numbers.
That's not a problem: just add a couple of lines to test for existence:
$i = 0;
while ($i6) {
$pick = mt_rand(1, 90);
if (!in_array($pick, $x)) {
$x[] = $pick;
$i++;
}
}
But if this is the only solution I'll do it in this way.
It's *never* the only solution :-)
