Ok, I sent it to everyone and you. Now can you answer my question please?
I type in
1
2
into my form in the program that i made, then when I view it, it shows
1 2
BUT if I check it in PHP My Admin it displays
1
2
So why is my program not showing those spaces?

In your email program hit "Reply ALL" instead of "Reply".
Until you work out how to do that, I'm going to ignore your emails.

The answer is to change this:
<? echo "".$row['post']."
to this:
<? echo "".nl2br($row['post'])."
like I said before...

Hello everyone, I am programming a blog, and most of it is done, except I

click the neter key to make a space, the MySQL database does not recognize
that space. How do I make it recognize it?
Unless you're stripping it out, it will recognise it. View HTML Source
and you'll see the newline is actually in there. A "\n" is not a html
newline so you need to convert it.
What you want is http://php.net/nl2br
Uhhh .... did you try this -- nl2br?

Stuff like this is a bug in your code. It has nothing to do with purism:
function inc_arg(&$arg) {
$arg++;
}
inc_arg(3);
You have specifically defined your function to modify the argument yet
you pass it something that has no storage and thus there is no way to
use that modification. For the most part I agree that we need to keep
the language as flexible and forgiving as possible, but where we are
able to detect code that obviously doesn't do what the programmer
intended, it is tremendously helpful to get a descriptive error.
As far as functions returning references, you are right that returning a
literal there sometimes makes sense, but this can also hide a bug which
is why this only throws a notice.
You could argue that we could try to look ahead and see what is actually
done with the passed argument to see if it is modified, or that we could
try to figure out whether the returned reference is actually used as
such, but that is technically extremely difficult given the way things
work internally. So given the choice between ignoring extremely
suspicious code like this and throwing an error/warning, I'd rather be
told about it and in the edge cases where I really do want the
equivalent of a NOP in my code, it isn't that hard to force it by adding
a dummy storage variable along with a comment explaining why you need to
do that.

hi Rasmus,
I understand the point you made below - you have made this argument before
and I, for one, accepted it as valid when I first read the discussion
on internals - which is why I avoided ranting about that (and changes like it)
But I am wondering what if any your views might be on the original rant (mine)
regarding purism/strictness that [I feel] is creeping into php for no good
(read 'pragmatic') reason?
as an example - I have in the past argued that discontinuing the ability to
define static methods in interfaces was against the grain and was given the
reply 'you don't understand OO fix your code' - in the last couple of weeks
static interface methods were reintroduced to help in a situation highlighted
by Derick R. I have had pretty much the same experience regarding late static
binding - to which (though nothing to do with my pleas) has finally been
capitulated
for inclusion in php6.... not inducive to an optimal uptake of php5 which given
the length of time it's been out is rather dismal when compared to the speed at
which php4 was taken up.
if you agree at all with my postulation then maybe you also see some need
to address the issue?
kind regards,
Jochem

Hi all,
Working on a PHP script at the moment where I want to be able to
extract a file (PDF file) from a mysql database and force the popup
of the File Download dialog, to allow the user to either save or open
the document (ie. and bypass loading the file using the browser's plugin)
I've found solutions on the net for doing this with a file using readfile()
but if I can get away with it, I don't want to create temporary files...
Here's what I've got so far (truncated...):
<?
..
// db query string extract the PDF file
$result = mysql_query("select file_data from brochure where
id=1",$connection);
$row = mysql_fetch_array($result);
$lengths = mysql_fetch_lengths($result);
// Grab the file contents as returned from the db
$pdf_brochure = $row["file_data"];
// setup headers to force download of $pdf_brochure into crap.pdf
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false); // required for certain browsers
header("Content-Type: application/force-download");
header("Content-Disposition: attachment; filename=\"crap.pdf\";" );
header("Content-Transfer-Encoding: binary");
header("Content-Length: " . $lengths[0]);
// send the file to stdout
print $pdf_brochure; // <---- problem might be here....
exit();
?>
This almost works but the problem is that this code still spawns a new empty
browser window, and I don't know how to prevent this.... Can anyone help ?
regards,
Matt.

not having temporary files and even the code you use have nothing to do with
the extra window problem - that is a client side issue over which php has no
control .. it's down to the browser settings (possibly) or (more likely) the
target attribute of the link in question.

don't open a new window to download it then ... i.e. don't use
'target="_blank"' in
the html defintion of the relevant link.

JSFileExtArray isn't an array, it's something else.
Use var_dump to see what it is and go from there.

I showed where the problem is and after var_dump all I get is NULL. I just
sent the code cause I thought it would be easier to see it in context, not
to make somebody trawl trough it. If its not an array how to find out what
it is? What can I do about it?

Put debug lines throughout your code and see where it breaks.
eg:
echo "at line " . __LINE__ . ", var is " . gettype($JSFileExtArray) .
"<br/>";
do that every 20 lines and then narrow the problem down from there.

What I need to know is that if when I fopen() or the other function you gave
me I get the variables that are assigned on the html, such as the option for
example, if its name is "test", could I access it retrieving the value $test
???
cause I really need to do it and I cant seem to know where to begin.

No. Those functions will retrieve the webpage exactly the same as your
browser does.
What would "test" be? Provide an example of what you see and what you
are trying to end up with.

Here it goes: in a certain page there is a dinamicaly generated Option ( one
of those boxes from wich you can select a certain thing in a list) I want to
retrieve the content of these options and the values assigned to each of
them.

So if you have:
<option value="test1">Test 1</option>
<option value="test2">Test 2</option>
You want:
$test1 = "Test 1";
$test2 = "Test 2";
??
preg_match_all('%<option
value=["\']*([^"\'>]+?)["\']*\s*>(.*)</option>%isU', $text, $matches);
That will give you an array that looks like this:
Array
(
[0] => Array
(
[0] => <option value="test1">Test 1</option>
[1] => <option value="test2">Test 2</option>
)
[1] => Array
(
[0] => test1
[1] => test2
)
[2] => Array
(
[0] => Test 1
[1] => Test 2
)
)
From there you should be able to work out what to do..

Yep, use the modulo operator like so:

the modulos operator:
read about what it does here:
http://php.net/manual/en/language.operators.arithmetic.php
here is a simple example of how to check if something
is odd or not (odd number that is ;-):
$x = 1;
$y = 2;
$z = 3;
var_dump(($x % 2), ($y % 2), ($z % 2));
