Does the xmlString print out?
Cuz my first guess is they turned off RAW_POST_DATA in the upgrade, so
it's just blank...

You also could make an array of checkboxes instead of hand-typing all
that...
$facilities = array(5=>'Credit Cards Accepted', 6=>'Towels',
7=>'Luggage Storage');
foreach($facilities as $f_id => $f_name){
$checked = isset($_POST['facilitiies'][$f_id]) ? 'checked="checked"

It's really up to YOU to choose the thumbnail constant size
and to decide what to do about the aspect ratio
You could crop or fill with black, or transparent or...
But making the thumbnail be 1/10th the original is your problem.
Here is one possibility:
$thumb_width = 50;
$thumb_height = ($height/$width) * 50;
You now have an image 50 wide and proportional height to the original.
Here is another:
$thumb_height = 50;
$thumb_width = ($width/$height) * 50;
That one is 50 tall and proptional width to original.

Hello,
mostly dealing with XML through the Perl-module XML::Simple I'm looking
for a simple solution within PHP. PHP4 and PHP5 is available but the DOM
XML-stuff seems to be bloated.
What I'm looking is a function that receives an XML-document as a
string, which parses the document which all its tags and attributes and
which then returns an associative array.
Is there anything available which comes close to my expectations?

simpleXML, which although it actually returns objects allows array like
access by virtue of the fact that the objects implement the necessary array
overload
interfaces available in SPL.

I have upgraded my development area to PHP 4.4.7 and I can no longer use the
LDAP extension. I only have 4-5 extensions enabled (GD2, PDF, ZIP, IMAP,
LDAP) but I get the following error from LDAP:
PHP Warning: Unknown(): Unable to load dynamic library
'./extensions\php_ldap.dll' - The specified module could not be found. in
Unknown on line 0
All of the other extensions are loaded just fine. Anyone know what is
causing this? The extension is where it is supposed to be.

Hi
I worked alittle with gd
It is my code for y(x)=sin(x)+cos(x):
function Graph($rangeLow, $rangeHigh, $step)
{
$img = ImageCreate($this->width, $this->height);
$background_color = imagecolorallocate($img, 0, 0, 0);
$white = ImageColorAllocate($img, 255, 255, 255);
imageline($img, $this->width/2, 0,$this->width/2 , $this->height,
$white);
imageline($img, 0, $this->height/2, $this->width, $this->height/2,
$white);
for ($x=rangeLow;$x<=$rangeHigh,$x+=$step)
{
y=sin(x)*cos(x);//custom function
//i dont know what should write here but i know that I should
write imageline() function
}
header("Content-type: image/jpeg");
ImageJpeg($img);
imagedestroy($img);
}
could anyone write a simple code that complete this code
I want to learn it
I dont want to use any software package
Thanks

Start working with GD would be my first answer...
If you can't use GD, then I would guess that somewhere "out there"
there may exist a software package that you can pass "sin(x)" to it,
and it will create a graph for you... No idea what it's called,
though...

That's exactly correct. Except I /think/ you should use "\n" instead of '\n'.

Thank you for the reply... =)
I'll check this... BTW:
array explode ( string $delimiter, string $string [, int $limit] )
So, I was wrong...
The right way, probaly, is:
$str=explode("\n",$_POST["my_text"]);
Thank you very much.

If it's coming from a <textarea> you'll want to use "\r\n" because a
textarea uses both a carriage return (\r) and newline (\n) to separate.
Otherwise each element of the array will have a \r on the end which may
end up causing you some issues later on.

I was wondering about this, I seem to recall that window/mac/*nix all do
it differently.
With a little Google'ing I came across this.
http://www.sitepoint.com/forums/printthread.php?t=54074
This was written in 2002, so I am not sure about the Mac = "\r".
Since they are using *nix now, it could be "\n" not sure
But the article had this to say:
Line breaks
People want to know how they can retain textarea line breaks in HTML.
You should store text in the database in its original format (e.g. with
just newlines) and then use nl2br() to convert newlines to HTML <br />
tags on display (thanks to the people here for teaching me that :)).
That's all good, except for one problem with nl2br(): it doesn't seem to
convert \r newlines (edit: this has now been fixed in PHP 4.2.0).
Windows uses \r\n newlines; *nix uses \n; Mac uses \r.
nl2br() works correctly on text from Windows/*nix because they contain
\n. However, if you get text from a Mac, nl2br() will not convert its
newlines (again, fixed in PHP 4.2.0). To remedy this, I use the
following bit of code to convert \r\n or \r to \n before inserting it
into the database. It won't hurt anything and ensures that nl2br() will
work on the \n only newlines on display. Also, it has the side effect of
saving 1 byte in the database per newline from Windows (by storing only
\n instead of \r\n). :)
PHP Code:
$txt = preg_replace('/\r\n|\r/', "\n", $txt);
Hope this helps

Another way to write that PCRE pattern is /\r\n?/ (one carriage
return followed by zero or one linefeed).
I recall also running into \n\r although I can't recall which system uses it.
As an alternative to PCRE, we can pass arrays to PHP's replace functions, e.g.:
$txt = str_replace(array("\r\n", "\n\r", "\r"), "\n", $txt);

Hi everyone, I have a small problem when exporting mysql into csv format.
The export works fine. The problem is, if the mysql table has a carriage
return, opening the csv file in excel will display a square box where the
carriage return is.
Displaying the table on a web page is fine.
Thanks for any help.
Haig
<?php
$csv_output = 'column1';
$csv_output .= "\015\012";
$result = mysql_query("select * from table");

In a more recent post, the op asked a question that is related to this,
in a way.
Here is what I think your solution would look like
$data = preg_replace("!\r\n|\n|\r!", "\r\n", $row['column1']);
$csv_output .= '"' . $data . '"';
Reason being is that Windows uses "\r\n" for line endings. More than
likely you are outputting "\n" This would cause windows to display one
of those funky boxes that you are talking about.
PS. be sure and use quotes around your array key names, otherwise you
might cause a PHP Notice on different systems.
$csv_output .= "\015\012";
}
header("Content-type: application/vnd.ms-excel");
header("Content-disposition: attachment; filename=" .
date("Y-m-d")."_my_report".".csv");
print $csv_output;
exit;
mysql_close();

I have a [gentoo] server with 2 apache installations ...
the std distro apache runs with php4 which includes an installation
of PEAR and PECL.
the second apache is compiled by hand and runs with php5 (also compiled
by hand) - obviously both of these are installed somewhere other than
the default. the [custom] php5 installation does not include PEAR/PECL
(when I built/installed it I skipped that because I was worried I'd get a
conflict
with the existing PEAR/PECL install and break something).
I would like to add the APC extension to the php5 setup, normally this is
as involved as doing the following:
> pecl install apc
only in this case that would install APC in the php4 setup.
the question is how do I go about getting a second/custom PEAR/PECL setup
running
which I can use with/for the php5 setup. is this even possible? or
am I stuck with a manual download, compile and install of APC for the
php5 setup as described here for instance:
http://carroll.org.uk/archives/2006/02/02/alternative-php-cache-apc-on-debian)?
tia,
Jochem
PS - STWF is giving me no joy, everything I find assumes the pecl/pear commands
are setup and running.

This is my code so far.
