Hi,
I have the following problem. I want to import data into my site via PHP
XML Parser, but I also want to include php string variables into
the .xml file and when the xml file is parsed the variables are replaced
whit the corresponding string.
So far all my attempts have been unsuccessful.
Here is the parser i have used
<?php
class XMLParser {
var $filename;
var $xml;
var $data;
function XMLParser($xml_file)
{
$this->filename = $xml_file;
$this->xml = xml_parser_create();
xml_set_object($this->xml, $this);
xml_set_element_handler($this->xml, 'startHandler',
'endHandler');
xml_set_character_data_handler($this->xml, 'dataHandler');
$this->parse($xml_file);
}
function parse($xml_file)
{
if (!($fp = fopen($xml_file, 'r'))) {
die('Cannot open XML data file: '.$xml_file);
return false;
}
$bytes_to_parse = 512;
while ($data = fread($fp, $bytes_to_parse)) {
$parse = xml_parse($this->xml, $data, feof($fp));
if (!$parse) {
die(sprintf("XML error: %s at line %d",
xml_error_string(xml_get_error_code($this->xml)),
xml_get_current_line_number($this->xml)));
xml_parser_free($this->xml
);
}
}
return true;
}
function startHandler($parser, $name, $attributes)
{
$data['name'] = $name;
if ($attributes) { $data['attributes'] = $attributes; }
$this->data[] = $data;
}
function dataHandler($parser, $data)
{
if ($data = trim($data)) {
$index = count($this->data) - 1;
// begin multi-line bug fix (use the .= operator)
$this->data[$index]['content'] .= $data;
// end multi-line bug fix
}
}
function endHandler($parser, $name)
{
if (count($this->data) > 1) {
$data = array_pop($this->data);
$index = count($this->data) - 1;
$this->data[$index]['child'][] = $data;
}
}
}
$url = 'data.xml';
$myFile = new XMLParser($url);
echo "<PRE>";
print_r($myFile->data);
echo "</PRE>";
$foo3 = "foo3";
?>
here is a sample XML file
<?xml version='1.0'?>
<!DOCTYPE chapter SYSTEM "/just/a/test.dtd" [
<!ENTITY plainEntity "FOO entity">
<!ENTITY systemEntity SYSTEM "xmltest2.xml">
]>
<document>
<data>
foo1
</data>
<data>
foo2
</data>
<data>
<?php echo $foo3; ?>
</data>
<data>
foo4
</data>
<data>
foo5
</data>
</document>
and what I get is:
Array
(
[0] => Array
(
[name] => DOCUMENT
[child] => Array
(
[0] => Array
(
[name] => DATA
[content] => foo1
)
[1] => Array
(
[name] => DATA
[content] => foo2
)
[2] => Array
(
[name] => DATA
)
[3] => Array
(
[name] => DATA
[content] => foo4
)
[4] => Array
(
[name] => DATA
[content] => foo5
)
)
)
)
So I want $myFile->data[0][child][2][content] to be equal to $foo3

Hi Ivan,
You might be able to use output buffering in conjunction with
including your xml file. Something like:
ob_start();
include $xml_file;
$content = ob_end_flush();
and then parse the $content string. If you are doing this from within
a function and you want access to global variables, you should import
all global variables first, via extract($GLOBALS);
Btw, this is just an idea, and untested - use at your own risk :)

Hmmm, come to think of it, it would only work if short_open_tags ini
directive is turned OFF, which in most cases it won't be :(

You can turn it off with a htaccess file.

I think you misunderstand the situation.

I've got a database of images (image data) and their exif data, I'm not
uploading any files. I want to make new entries in that DB, new images that
are thumbnails of the present images. I can do that without creating files,
but I can't get exif data of these thumbnails, because there are no files.
The exif data for the thumbnails isn't the same as for the full images.
In PHP its not easy to keep EXIF data of JPEG or TIF files as it is if
you use PHP functions to recreate the temporary files in some dir.
Basically when you use tempnam() it creates a temporary file. To get the
thumbnails you must rewrite the resized file to some place (if you want
real thumbnail image). You cannot preserve exif data with any of PHP
functions available. You probably have to use some specially developed
code to write exif data. I tried this class
http://www.zonageek.com/software/php/jpeg/
I tried to use it but either it could not write all the exif data or I
was not calling required functions properly.. It requires pear..
Other you can try is http://pel.sourceforge.net/
But both of these will require you to write a resized image and then
write exif data (common for both, original and resized) retrieved from
the original image to the new thumbnail you generated with additional
image specific exif info.
Best is to maintain thumbnails.. with exif data written in it too.

No, that's not correct. You can take an image from a db, create a
thumbnail while it is in memory and display it. You don't need to
make it a file first.

That *is* correct. You must rewrite the resized file to some place and
that place can be /dev/foo (memory or disk). I did not say you must
write it to /disk/.

Hi Chris,
Goal was to get postgre to execute/import an sql dump file, ie not to
write import-export functionality myself. In the end, I used piping,
something like this:
system("type $filename | \"C:\Program
Files\PostgreSQL\8.1\bin\psql.exe\" -h localhost -p 5432 X6tmp
\"postgres\"");
But thanx anyway :)

You might be better of not doing this with php.
Create the dump on the first machine.
Copy the dump (scp, rsync, copy via samba-mounted drive, whatever)
import it
It depends what your end goal is.

Hello,
Most sites today seems to be based on this style:
include(top);
include(current_page);
include(bottom);
If one wants to set cookies from current_page, how should that be handled with
as clean source as possible?
Before I had the top and bottom output as functions that are called from each
page, so I can call header stuff before it's executed. But it's not a very good
looking approach.
I did it like this in every page:
include(top_bottom_lib);
// cookie stuff
echo getTopPage();
// page stuff
echo getBottomPage();
I hope you understand my problem.
Thanks
Best regards Emil

>From the php manual:
Like other headers, cookies must be sent before any output from your
script (this is a protocol restriction). This requires that you place
calls to this function prior to any output, including <html> and
<head> tags as well as any whitespace. If output exists prior to
calling this function, setcookie() will fail and return FALSE.
So it has to go before ALL output otherwise it will fail. You're stuck
with putting it in the 'top' file or at least before you echo any
output.

You can also use output buffering, write cookies from anywhere, and at
the end of execution buffers will auto-flush.

Just for editing php files under linux I found the eclipse plugin

Very nice screenshot:

I am a linux newbie but just compiled freetds on my fedora box. I used the
basic options:
./configure
make
make install
make clean
According to the docs it should install to /usr/local/freetds
After all this I don't have a freetds folder in /local/. If I go into
/usr/local/bin, I do have a tsql which I believe are part of freetds so I
think it installed. Where do I set the directory when I recompile php
--with-mssql?
Thanks!

If the message goes to an address with a POP3 mailbox, you can always
get the message body using a POP3 client script using for instance a
class like this:

Hi there!
I've found out that I can use expat XML, but I can't figure out HOW to
use... it seems simple, but I tried and can't figure it out...
I'd like to get retrieve info from
http://www.frisim.com/frisim/servlet/rss?searchString=google
and convert it to html...
I've read a lot a of text for Expat, but found no really good example (I
found one at phpbuilder.com but with links that went to xml-files that
didn't exists ):
Someone who have used expat.. ..and can give me a hint...
