[PHP] FPDF ?
For those of you with FPDF experience. I've just begun using it and have figured out how it works I think. I am still having trouble with the bottom of the page tho. Seems that if I get too close to the bottom margin and my data line exceeds the amount of available space, my MultiCell elements print some of their contents and then my Footer gets printed and then I go to a new page where some small amount of the remaining data for that line gets printed and then a new page is output and repeat. This can go on for 3-4 pages before things work out and my report continues until it gets a full page again and then it all happens again. I know it sounds complicated, but I'm hoping someone else has experienced this kind of learning curve and can give me a clue as to what I'm doing wrong, or at least what's happening. Even better would be an algorithm for detecting how much space I have left so I can avoid these split lines and perhaps solve my entire problem. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

However, if func2 is defined in some_other_file.php, you need to
include it in this_file.php (where func1 is defined) first:

some_other_file.php:

function func1 ($flag1, $flag2) {

[PHP] I'm missing something
I have a discrepancy in the number of elements in my arrays and can't see
why.
Here is some code:
Note the lines with the ***
*** $plyrs = 0;
unset($plyrnames_ar);
unset($js_names);
unset($js_seeds);
*** $rows = mysql_num_rows($qrslts);
***echo "in mysql there are $rows rows";
while ($row = mysql_fetch_array($qrslts))
{ // build the name value here
$mi = ($row['MI']=='') ? '' : " ".$row['MI'];
$nm = $row['LastName'].", ".$row['FirstName'].$mi;
if ($row['srtdbls']=='X')
{
$mi = ($row['partMI']=='') ? '' : " ".$row['partMI'];
$nm .= "/".$row['partLN'].", ".$row['partFN'].$mi;
}
*** $plyrs++;
$plyrnames_ar[$nm] = $row['Draw_pos'];
}
*** echo "before sort there are ".count($plyrnames_ar)." in
plyrsnames_ar";
ksort($plyrnames_ar);
foreach ($plyrnames_ar as $nm=>$sd)
{
$js_names[] = $nm;
$js_seeds[] = $sd;
}
*** echo "plyrs is $plyrs and there are ".count($js_names)." entries in
js_rnames and ".count
***($plyrnames_ar)." entries in plyrnames_ar and ".count($js_seeds)." in
js_seeds";
exit();
The problem is that my $plyrs field comes up 18, while in truth there are
only 17 rows of data in my database.
All of the other array-size counts echo out as being only 17, but my $rows
and $plyrs fields come up as 18. I was having problems with my javascript
showing an undefined array element and took a bit o time to determine what
it was and where it was happening.
Questions - does mysql_num_rows return a extra row that somehow doesn't get
processed in the while loop? And if it does how come the counter ($plyrs)
that I put into the loop comes up higher than it should.?

That said - format your URL as a GET string and there's your variable. Ex.: http://server.domain.com/(scriptname)?variable&anothervariable&anothervariable Or - if this url is coming from an already running script, you could post the var to a session var and then send a url without the script name and let your server's default document (index.php ?) receive it and look up the session var, but that's a pretty silly way to handle things just to hide the scriptname.

Nope - that didn't work. Tested it against 1900, 1300 and 13:00 and all
came thru as OK.
Also - I don't understand at all the following:
> FYI: ? is equal to {0,1}, and [1-9] to [123456789] (and therefore [1-2]
> to [12]).
I know (?) that [1-9] validates any digit from 1 to 9 - I was already using
that.
And your point about [1-2] doesn't make sense to me since I need to validate
10:00 which [1-2] in my usage would cause 10:00 to fail.
And I don't know what ? means at all.
FWIW - I couldn't find much in the way of tutorials on the meanings of the
various chars in regexp's.

Thanks for the work you did, but I really wanted to try to solve this using
the more "elegant" way, which from my readings over the last year as a new
php developer, seemed to be the regexp methodology. I'm so close - it's
only the 1300,1400,etc. time values that are getting by my expression.
And thank you Shiplu also for your simple, but non-regexp, solution. Yes -
it works and I had something similar that was just missing one more check
when I decided to explore the regexp method.

I'll have to study your regexp - a lot of stuff I don't understand yet in
play there. Thanks for the sample!

OK - I don't yet understand how this works, but it seems to work for almost
all cases. The one erroneous result I get is from a value of 0040 (which I
convert to 00:40 before hitting the regexp). It comes thru as Ok. If you
have a fix for that I'd appreciate it - otherwise I'll have to devote some
book-time to mastering this string and come up with a fix myself.
Thanks again!!

It may appear harsh, but as far as I'm concerned it is daft to make assumptions like that. You've essentially disallowed 12:nn am, but allowed 1:nn am, 2:nn am, 3:nn am, etc, because you're not validating the data in a non-ambiguous way. I have no idea what you're developing, but you're making a big assumption about the data that you're getting, which may appear reasonable to you, but to me it's daft.

The scheduling only pertains to basically daytime hours, typically 8:00am to 6:00pm. The information is used for display purposes mostly - there is no "calculating" going on with the data. Consequently, there is no need to be all-inclusive on my allowed times since they will never be used. I just want to validate the entries to be sure that a valid time has been entered for that period of a day. Noone is going to schedule anything for a midnight hour, not even a time after 8:00pm.

Since this code does nothing other than assign a value to $calling_page
based upon the content of a GET variable, what do you mean by "not able
to get the $calling_page populated with any values.".
Are you simply saying that "$calling_page does not have a value assigned
to it"? And if that is what you meant to say, then the answer is that
your GET array does not contain an index of 'page'. Of course, even if
that were true, you would in fact have a value in $calling_page and it
would be simply: "Title 1 - ".

Do you have errors and notices set to display, or have you

Are you passing a page parameter through the URL? The error is basically
complaining that you're not.
So - is this INDEX.PHP script being called by a form on the client
screen that has a field with the name of 'page'? And is the script
(INDEX.PHP) being called via a GET method (and not a POST) in the
tag of the currently displayed page?

[PHP] The end of "mysql"
So with the announced end of the mysql functions (and switching to a different extension), one would think that my isp/hoster would be a bit more interested in my dilemma.

A series of emails with my tech support told me that the shared server farm does not get "mysqli" - only their business servers.

[PHP] tricky code problem
This is a tricky one but let's see if I can explain it. 1 - using a menu screen I have a link that calls a js function that opens a popup with a form in it; 2 - the form receives some user input (a login) and then the user clicks a submit button; 3 - the button has an onclick that calls a js func that does an xmlhttprequest to a php script using a GET with some parms; 4 - the php script called above returns a true/false value back to the js function; 5 - the js function returns the true/false value back to the html tag that triggered it; 6 - the form in the html containing the input tag gets submitted if the return was true, calling a different php script with a POST and definitely no parms in the action value of the tag. What shows up on my address bar (ie) is a composite of the script name called in item 6 along with the parms (ie, GET values) from the js xmlhttprequest string in item 3 appended to it. Now all of my scripts have a header that eliminates caching, so that's not it afaik. I've actually closed my session and come back an hour later and this still occurs.

Well.. many things changed during last 30 years. Cobol is not
mainstream, we have got OOP, Java, Python, Ruby, Google and other
great things :)
I am talking about stateful application server. There are plenty
examples in other programming languages: Java has Jetty, Tomcat, Ruby
On Rails, Python and Passenger WSGI.
All of them have one common thing: application persist in memory
between requests. Even for interpreted languages (such Ruby) - this
has advantage of loading sources only once, parse it only once and
initialize memory structures for those definitions only once. On the
opposite - PHP loads EVERY single resource on every request. This is
why it needs op-code cachers, accelerators etc.
Another advantage of using stateful application servers is that you
can simply keep gloabal state of your application (global variables,
static object properties) in memory. It simplifies many tasks which in
PHP require sessions, writing files with serialized data and
deserialize them on every request...
Just imagine such scenarios:
now PHP acts like this on every request:
1. locate resources (source files in this case), parse and load them
(possibly with op-code cache)
2. initialize global context ($_SERVER, $GLOBALS, $_POST, $_GET, etc)
3. run code
4. destroy all resource and free memory for next request
persistent application servers load resources only on startup (or when
needed) and keep them in memory until programatically freed or until
end of application (server shutdown). So every request looks like
this:
1. initialize global context
2. run already parsed code
is that makes whole thing clear?
Another nice example - simple counter. In PHP you have to:
1. read file with counter
2. increment value
3. write serialized value to file
...on every request.
in Java (for example) you just write class:
class Counter {
static private counter = 0;
public void increment() {
this.counter++;
}
}
and because class definition persists in application server - static
member is maintained between requests and whole things works as
expected...

Sounds to me like you'd need more hardware to support such a concept. I
realize that memory can be mapped to disk to avoid the need to have HUGE
amounts of ram in your server(S!) but with ever-increasing processor

So,I want to know how to solve it.
Thank you.
Well, there are basically 2 ways:
1. introduce locking; you can lock the file and have the other script
check if the file is locked. If so > have it usleep() and check again.
2. If you can run gdnsproxy in parallel, you could instead change the
script to make $fdoc_tmp/temp_proxy unique for that script. So instead
of just writing, you first check if the file exists, if so, create a
file with a different (non-existent) name and then try again. Otherwise,
use the first name. Then pass the 'unique' name to gdnsproxy.
Even simpler - use the 'tempnam' or 'tmpfile' functions to always have a
unique name and avoid having to check for an existing file.
Amazing what the php Manual has in it...

You should have your error settings set to show everything.
I include these three lines in all my development work:
error_reporting(E_ALL);
ini_set('display_errors', '1');
set_time_limit(2);
In this case, I do think that your insert statement is incorrect - I
could be wrong. I think the VALUES clause s/b just 'VALUE'. Also if
you added MYSQLI_ERROR to your error handling you should get a very

ON second glance - your table seems to have 4 fields:
id,date,id,name,screenshot.
Your insert has 5 values: VALUES (0, NOW(), '$name', '$score',
'$screenshot')
That right there is going to throw an error.
BTW - You're saving the name of the screen shot file but are you
actually saving the uploaded file somewhere else in your code? Didn't
see it here and just wondered.

example he had sent me a while back I've messed around with it and modified it
to better understand it:
function filename($prefix)
{
$matches = glob('images/property_pics/'.$prefix.'*');
foreach($matches as $filename){
return $filename;
}
}
echo completeImageFilename($row['MLS_No']);
With the above code I only get the first image of each picture name, but when I
change return to echo, it groups and displays all the pics that have the same
picture name.

the code presented is problematic in itself. Very forgiving, but
perhaps someone should have suggested that he post "actual code" when
looking for help in the future, and not some typing that is supposed to

In this case, I"m looking for the function he called

Sorry about that Jim, I accidently typed the wrong function name. Here's the
corrected code. Everybody's answer was spot on and I learned a great deal
about return and echo. :-)
function completeImageFilename($prefix)
{
$matches = glob('images/property_pics/'.$prefix.'*');

return $filename;

echo completeImageFilename($row['MLS_No']);
Hopefully you got my point tho - don't post code that is not THE ACTUAL

I was afraid when I first posted that question, it would give that impression.
I've known what echo does, but not very much about return. Also a part of me
has always wondered when I'm studying code from things like wordpress I don't
think I have seen any echo statements. If I did it was very very few. (hint:
why I asked about templeting systems about a month ago.)
As for the code above - once again it looks like you have posted a
re-typing of some code you have tried to execute. I say that because
you have a query and a fetch of one record of the results THAT HAS
NOTHING TO DO WITH THE REST OF THE CODE!
The query is geting a number out of the database and putting the value in
$prefix.
NOT IN THIS SCRIPT!!
Also - you have an array
being used as part of the Rel tag? What's up with that? (I think you
meant to use $match - but that further verifies that this is NOT the
code you ran.)
I tried using $match and $matches because I got confused there for a bit and
changed it.
$MATCH WOULD WORK; $MATCHES WOULD NOT. It's suppose to be a 'name' -
so why would you put an array reference in the Rel attribute?
Finally - the code is (from your description) doing exactly what it is
designed to do (the running code that is).
It sure is, and I found out what my whole problem was this morning before I
went to work. My problem was lightbox was not putting all the images in
$match. but I never suspected it until Matijn and Marco, posted an example of
code and It turned my attention to the piece of code... put a bunch of
images in a folder and try running the code. You'll see what I'm talking
about.
THATS' CAUSE YOU DIDN'T LABEL THEM WITH $MATCH!
All the (repeated) "echo"
statements are going to put something on your web page.
Yes I was getting stuff on the page, and then when I'd try and build onto the
idea, and things broke, I'd try something else, and something else, until
finally I'm all confused with it. for example I'd forget to terminate something
and get a blank screen and imediately suspect it was the new code I
introduced. After the millionith time I started realizing when I get a blank
screen, I forgot my semicolon at the end of a line somewhere.
The question
you have is (apparently) how to hide them, since I believe Lightbox is
going to have to have them present in order to do its thing.
That's part of it. the other part is that lighbox is supposed to do that
automatically and it should, and that's another reason I was getting confused.
like I said earlier run the code and you'll see what I'm saying.
I HAVE USED LB - IT DOESN'T HIDE THINGS. IT DISPLAYS THINGS. THINGS
THAT YOU PROVIDE - WHETHER YOU HAVE THEM HIDDEN OR NOT.
Feel free to check out a site I developed - voorheesvilefd.org. This
site uses plenty of php and LB to display random photos drawn from
folders across the site.
And so -
in parting - I think you need to develop some html knowledge to

(BTW - that last was a hint.) I've read plenty of PHP books I own at least 5 and ALL of them I've read hardly ever explain anything at all. They just throw some code in there and say "this is what it does" and gives a picture of the finished product. Total waste of my money! Also, how am I going to learn PHP if I've got to mix it all up with CSS. It's just going to make things harder and more confusing on me. I only threw lightbox in there because I knew I didn't have to do or learn anything special and to put a smile on my face if it worked. After all, if it can't be fun, why do it? I rarely post anything to this list, because almost everything asked is above my level of understanding. But, speaking as a relative beginner, I have a few comments here. 1) Books. I, too, have read a lot of PHP books. In the end, the ones I've found most useful were by WROX press. Their "Beginning PHP4" by Choi, Kent, Lea, Prasad, and Ullman was one of the best "intro to programming" type books I've found for the way I learn. It's now obsolete, but the core information is still good. I haven't read through the Beginning PHP 5.3 version as thoroughly, but it also seems to be pretty good. You might also want to check with local community colleges to see if someone offers a basic course -- PHP, C, C++, something like that. The language may be different, but the concepts remain the same. 2) "They just throw some code in there and say "this is what it does" and gives a picture of the finished product. Total waste of my money! Also, how am I going to learn PHP if I've got to mix it all up with CSS." This one's harder. These days CSS is part of the web, and you're stuck with it if you want to do anything complex. So here's my advice: Find something simple to experiment with. Don't start with a complex project, start with something that doesn't actually do anything useful. When I start trying to understand a function I haven't used before, I build a new page called something like "foo_test", where foo is the name of the function. These days it might be ip2long_test, or something like that, but I still have some in my test folder with names like "echo_test.php" where I was trying to figure out how that function worked. Start there. Do something simple. Lightbox may be too complex. Maybe build a fortune cookie webpage, where every time you click a button it reloads with a new fortune. Learn to pull fortunes out of a file and out of a database. Once you've got the hang of that, start using CSS to change how it looks. Once THAT's working right, figure out how to use JavaScript (you're going to need it sooner or later!) and AJAX to make it reload the fortune without reloading the whole page. Yeah, it's a boring project. But it's a stepping stone to doing what you really want to do. The alternative is to do what I did: start with a big project, and accept that you're going to rewrite it dramatically later. I started with a book inventory system. First I built a login and authentication system -- that builds a form, and queries the database to see if the userid and password are correct. Then I built a system to list what was in the book table for the database. Around the time I finished that, I realized I needed more granularity in user logins, so I went back and rebuilt the login tool. Then I realized I didn't actually have a way to add stuff to the DB, so I built that tool and so on. It ended up taking me something like a year, because I'd never looked at PHP before, and I've now scrapped the entire project and rebuilt it. Why? Because I did just about everything wrong. It just plain wasn't practical to try to fix it. I'd never learned the basics, I just threw myself at a big project to see what would happen. Good luck! -Andy McKenzie Excellent advise! When learning any language, those small steps you suggest is how I've always learned the language. A few years ago I ran across someone who didn't know a thing about programming but wanted to learn. The first project he wanted to tackle was to write his own online role playing game. You know, like World of Warcraft! Uh, yeah. I steered him away from that! Take care, Floyd All great advice but alas, I fear that my long-winded response that began all these succeeding advice columns has steered our OP away from this list. He thinks we're above his level (we are) and that he needs to start somewhere else, which means he'll probably repeat the mistakes that have been mentioned here.

PHP The Right Way If you are developing for the Web, the chances are high that you have to deal with PHP on a regular basis.

Sounds like a good idea, but as for me - if I was a newbie I'd have a problem with their very first instructions. It says right off the start to type in the following: php -5 localhost:8000 which when I do (from a dos prompt) gives me a nice description of the command, but fails to do anything else for me. So how does this (as it says) "help me learn with the hassle of configureing and installing a full-fledged web server"? Are you running 5.4+? First thing it says is "Use the current stable version (5.4)". The PHP server (-S) is not available in anything earlier. I'm not running anything. It says to type a command and I did.

Hi all,
I am having a problem with comparing time. I am using the following:

strtotime($showsRecord['end_date']));
if ($todaydate > $showenddate):

The problem that I am encountering is that PHP is rendering the reverse of
the equation. For example:
If today's date is *11 Nov 2012* and the show's end date is *18 Nov 2012*,
the message that I am getting is *the show has ended* which is wrong. A
test example is at http://www.lakesidesurrey.co.uk/test.php.
You can also me what I am doing wrong?
Thanks

Besides the minor fact that the code has syntax errors, the problem with
it is your if is backwrads. The facts are: today is less than end date,
so your if should show "The show has ended" since you are asking if
today IS GREATER than the end date.

That's a strange way of writing a switch, IMO. You should be using the if

Maybe I'm way out of touch, but when I look at php.net for the syntax of
the switch statement I see:
switch($var){
case (value):
(do something)
case (other value):
(do something else)
}
IN your example, you are using a switch syntax that is nothing like
that. I think that your "case " statements are not actually evaluating
the value of $count, but are themselves evaluating to a true value that
has nothing to do with $count.

That `switch` is evaluating to true each case. It's an alternative of using

My point was that the OP is using a widely different syntax for a Switch
statement, one that I don't understand at all. According to the Manual
his statement should be:
>>>> //switch ($count) {
>>>> //case (> 14):
>>>> //$boxes = 3;
>>>> //break;
>>>> //case (> 7):
>>>> //$boxes = 2;
>>>> //break;
>>>> //default :
>>>> //$boxes = 1;
>>>> //break;
>>>> //}
To answer Iñigo's comment - the OP's version is very much like an
If-ElseIF structure, and nothing like a Switch.

I actually do not allow the user in the connection string to connect locally
which makes me think it is not accepting the host parameter and defaulting to
the localhost.
I would expect this if connecting localhost but the IP is not the local host IP.
My question is WHY is it changing the host parameter?
Like I said just a WAG, but are you sure about my other questions? My
point is perhaps the error message itself is a little confusing and the
response from the sql server is using the term localhost to refer to
itself, but that message is getting passed back to your server and then
to you, causing perhaps(?) some confusion.

In reading your question again, I get what you are saying. Let me explain.
It is not actually saying 'localhost' it is saying 'server1.mydomain.com' of the
server I am connecting from.
not the server2.mydomain.com.
I have ensured the path is correct, PING, NSLOOKUP from the server trying to
make the connection.
It changes the domain
would have been nice if you had specified the message exactly the first
