I'm not sure how it looks etc with with soapui but I noticed you
mentioning you don't want to mess with nusoap. I've used nusoap for
both client and server uses for years and I'm really impressed with how
easily it works. Using $soapInstance-request and
$soapInstance-response the xml is displayed where you can see how it
was created based on the array you fed the instance before sending for
your message. It makes troubleshooting much easier for me.
That being said I don't send attachments. However just doing a quick
google on nusoap attachments (without the quotes) has mention of
people sending MIME attachments and one listing an issue with DIME
encoded attachments yet another explaining that he solved the DIME
encoded issue and referred to wrox book open source webservices page
315 which is an on-line book.
Sorry no quick silver bullet, but I would highly recommend looking at
nusoap if only as a test.

you tried hitting the service w/ soap ui?
http://www.soapui.org/
although its written in java, its an indispensable testing tool, imho,
and i
always give it a shot when im having soap troubles. i might try to see
if
you can get a successful response from the service w/ it.

Hi Nathan!
Thanks for the reply. I'm download it as we speak. Hopefully it'll
give me some sort of answer as to what is going on. I really haven't
found out enough about the SOAP standard enough to know what is
expected behavior, etc. I know I can see all of the raw data there,
just ext/soap doesn't seem to like the multi-part. Maybe soapUI will
give me some sort of answer for this.
After using soapUI I've determined that the SOAP response gives back
an envelope and has one attachment. Does anyone know if the SOAP
extension can handle attachments? I'd really rather not mess around
with nusoap or the pear soap package. I don't see anywhere on the
manual where it is possible to download attachments. Hopefully
someone else has dealt with this before.

I'm using a php script which performs three xml queries to other three

Although I'm sure the connection to the database is ok, I sometimes get
an error of this kind:
*Warning*: mysql_fetch_object(): supplied argument is not a valid MySQL
result resource in ...
This does not happen every time i run the script, only sometimes.
If I echo the query, copy and paste in phpmyadmin, or if I perform the
same query in a script that does only the query without the rest it works!
After troubleshooting this issue I noticed that it usually failed when I
had a big set of ids (positive response from more than one server). This
means that the script used a bigger amount of memory and probably more
resources, but I did not get an out of memory error, I got the one
described bfore.

That's new. :) Well, to give you a good measure: keep the cardinality between 30 to 70-80 percent of your total records in a column. But sometimes your field is NULL or empty, so it really depends. You can't just put it into a standard configuration. And it also really depends on how many records a table contains etc. Besides that, benchmarking your development environment (you do have one do you?) can gives you a good idea on how your hardware and setup performs. I think I missed that part. For I am concerning query, index, and entity design most of the time. Aschwin Wesselius -- Regards, Shelley

That's new. :) To explain that further the idea is that if you have something like a 'status' field which can only hold 5 values, there's no point indexing it if there's a reasonably even spread. If you could only ever have a handful of fields with a status code of '1', then it's worth indexing if you have to find those particular records quickly. I don't think mysql supports partial indexes, but some databases do so you only index the fields that match a certain criteria. I'd suggest a more thorough approach to working out what to index rather than just trying to guess what's going on. Another piece of low-hanging-fruit is to index a field that you will be joining on frequently. The fact is, we seldom use join. Because we think it very slow to make it working on two tables with millions of records. Though we did not try it. :( Point above about spread still applies, but if you can join index to index, the join goes a lot faster. (A primary key in MySQL is always indexed.) How much is the *a lot*? Thanks. :) Having too many indexes rarely if ever costs on read (as far as I am aware), but it does cost on write to update the index.

Re[2]: [PHP] equivalent to perl shift function
Hi Chris, In perl ther is the concept of @_ which is the list of incoming parameter to a subroutine. It is possible to have something like my $sock = shift; As I understand this the first parameter of the @_ list would be shifted. I see for array_shift there must be an argument, the array name to shift, while in perl if the array name is omitted the @_ function list is used. Is ther a php equivalent to the @_ list or how might I use array_shift to achieve the same result as in perl?

I''ve no idea why you want to handle arguments in the same way as perl does - but func_get_args() returns the array of arguments to the function and you can shift that with array_shift() if you like. http://www.php.net/manual/en/function.func-get-args.php -robin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

i dont really see how that gets him the answer without at least checking the
number of elements in the array after filtering it w/ array_filter;
Because an empty array evaluates to false when cast to bool (which is
implicit in a conditional).
So this should work fine:

Hi, I'm having a strange problem with fopen
For clearence, here is the phpinfo page:
http://www.grondengoed.nl/phpinfo.php
I will shortly explain the problem I'm having:
$imagenamesmall = $foldersystem . '/' . $id . $imgstr . '-s' .
$i . '.jpg';
echo $imagenamesmall; // For debugging purposses -- returns
exactly what I want.
//attempt to create folder
@mkdir($foldersystem);
@chmod($foldersystem, 0777);
//save picture
if(!($handle = fopen($imagenamesmall, 'w'))){
echo Cannot open file (31);
exit;
}
//$imagesmall, contains the image resource
if(fwrite($handle, $imagesmall) === FALSE) {
echo Cannot write to file (32);
exit;
}
fclose($handle);
Erverything works perfectly fine.But one thing, it doesn't give the
file the name that it should get. A name for instance has to be:
54961tdtdtdtd-s0.jpg
The number is the id of the database row, the 8 characters are random.
-s stands for small and 0 is the picture index.
When I echo the value, I get what I want. But when I save it, the
random 8 character string had become a totally different 8 character
string :S.
I have googled and checked things over and over again, cost me hours
and I still haven't found the reason. What is noticeable is that when
I leave one character away from the name, the value IS what it schould
be:S.
I really hope you can help me, if you need further info yust ask.
Thanks in advance.

Re: [PHP] Re: Question regarding fopen
This problem is getting stranger by the minute.
I will explain in a little more detail what the script is actually for..
It is an advert site and per advert, you can add 5 photo's..
Now you set the $i = 2; When I set the $i (which indictates the index
of the photo, so $i = 5; is the last photo) myself, it works..
But normally I get the $i from the database, because there is stored
how many photo's the already are in the advert.. When I use that value
it doesn't work at all.
When i set $i = 2.. It works :S,, but when the value it gets from the
db also is 2 than it doesn't work (it is like it just doesn't want me
to get it working :P)...
Reproduction would be very difficult, because it is in this very
specific situation...
Maybe I am able to give you access to the FTP but that is a bit risky
for me, not that I don't trust you, but the website is not mine..

$imagenamesmall = $foldersystem . '/' . $id . $imgstr . '-s'
.
$i . '.jpg';
echo $imagenamesmall; // For debugging purposses -- returns
exactly what I want.
//attempt to create folder
@mkdir($foldersystem);
@chmod($foldersystem, 0777);
//save picture
if(!($handle = fopen($imagenamesmall, 'w'))){
echo Cannot open file (31);
exit;
}
//$imagesmall, contains the image resource
if(fwrite($handle, $imagesmall) === FALSE) {
echo Cannot write to file (32);
exit;
}
fclose($handle);
Erverything works perfectly fine.But one thing, it doesn't give the
file the name that it should get. A name for instance has to be:
54961tdtdtdtd-s0.jpg
The number is the id of the database row, the 8 characters are
random.
-s stands for small and 0 is the picture index.
When I echo the value, I get what I want. But when I save it, the
random 8 character string had become a totally different 8
character
string :S.
I have googled and checked things over and over again, cost me
hours
and I still haven't found the reason. What is noticeable is that
when
I leave one character away from the name, the value IS what it
schould
be:S.
I really hope you can help me, if you need further info yust ask.
Thanks in advance.

[PHP] mysql query and maximum characters in sql statement
Hi,
I have written a program which imports the tab delimited file and insert all
the line from file to the mysql line by line.
I am succeding in the above case. but problem with the above method is its
taking to too much time while inserting into the database.
The file's size will be more than 5000 lines.
Then i tried to build a string of ; seperated queries. as follows
for($i=1; $isizeof($array); $i++){
$insert_string .= insert into tablename (v1, v2. v6)
values('$array[$i][1]', '$array[$i][2]'. '$array[$i][6]');;
}
if(!empty($insert_string)){
mysql_query($insert_string, $conn) or die(query failed : .mysql_errror());
}
Its throwing error saying check the manual for right syntax.
After investigating in some sites i come to know that its problem of
limitations in query size.
I also tried with SET GLOBAL max_allowed_packet=3000;
Then also its throwing the same error.
Can anybody tell me how to fix this error and reduce the inserting time with
a single statement instead of writing more insert statements

Re: [PHP] Re: Question regarding fopen
Small correction $i = 4, means the last photo not 5..
Not so important but still.:P
2008/5/1 Joep Roebroek [EMAIL PROTECTED]:
This problem is getting stranger by the minute.
I will explain in a little more detail what the script is actually for..
It is an advert site and per advert, you can add 5 photo's..
Now you set the $i = 2; When I set the $i (which indictates the index
of the photo, so $i = 5; is the last photo) myself, it works..
But normally I get the $i from the database, because there is stored
how many photo's the already are in the advert.. When I use that value
it doesn't work at all.
When i set $i = 2.. It works :S,, but when the value it gets from the
db also is 2 than it doesn't work (it is like it just doesn't want me
to get it working :P)...
Reproduction would be very difficult, because it is in this very
specific situation...
Maybe I am able to give you access to the FTP but that is a bit risky
for me, not that I don't trust you, but the website is not mine..

Re: [PHP] Fun with SOAP.
On Wed, Apr 30, 2008 at 3:53 PM, Larry Brown [EMAIL PROTECTED] wrote: I'm not sure how it looks etc with with soapui but I noticed you mentioning you don't want to mess with nusoap. I've used nusoap for both client and server uses for years and I'm really impressed with how easily it works. Using $soapInstance-request and $soapInstance-response the xml is displayed where you can see how it was created based on the array you fed the instance before sending for your message. It makes troubleshooting much easier for me. That being said I don't send attachments. However just doing a quick google on nusoap attachments (without the quotes) has mention of people sending MIME attachments and one listing an issue with DIME encoded attachments yet another explaining that he solved the DIME encoded issue and referred to wrox book open source webservices page 315 which is an on-line book. Sorry no quick silver bullet, but I would highly recommend looking at nusoap if only as a test. Hi Larry, I am receiving a multipart mime attachment from Amazon. The idea is we request a report and get a response. This response differs from any other response I have seen in that it is multipart. I searched all over the place for a way to get it to work correctly. The soapUI program is the only one so far that has been able to show me that I get a proper return value that can be parsed. soapUI shows me the envelope XML and then has a button on the bottom that says there is an attachment that I can save to a file. So from this I know that it is possible to handle this type of request correctly. I just haven't been able to find any real examples on how to use it. I wanted to keep everything using ext/soap since it is c code and very fast. Plus there are other parts of this program already utilizing it. So far I have my backup plan working using curl, a regex, and simplexml. ;) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] extending Xpath
Hi,
I was wondering if it was possible to extend the DOMXpath object in a
similar fashion to the DomDocument.
I was hoping to write a wrapper to provide an interface similar to
prepared statements in the db libraries for the xpath processor.
$xpath = new myxpath();
$stmt = $xpath-prepare(/foo/[EMAIL PROTECTED] = '?' ]);
$stmt-bindParam( '?', $potentiallynastystring );
$x = $stmt-execute();
I have tried :
final class timber_utils_domxpath extends DomXpath
{
public function __construct( DOMDocument $dom )
{
echo in here;
parent::_construct( $dom );
}
}
but I get the following error
Fatal error: Call to undefined method DOMXPath::_construct()

Sure, check with a MySQL list via http://www.mysql.com
Otherwise, split it up into multiple inserts.
I currently have a script which reads a 550,000 CSV file and uses
?php
// read file
// for each line, do the following
while ($in != EOF)
{
$line=explode (',',$in);
$out=insert into table values('','$line[0]', .);
fwrite ($outf, $out);
}
then I have another file that
?php
//read the file line by line
//connect to db
$sql = $inLine;
mysql_query($sql) or die();
?
which all in all takes about 10 seconds to run the conversion and then the
inserts.

Re: [PHP] Categories like wordpress
Is this how its done or am I barking up the wrong tree? You have multiple options: 1. Fully normalised, where you have three tables - one for your articles, one for your categories and a link table. 2. A SET MySQL datatype which will allow upto 32 predefined categories. 3. A simple CHAR type with the category names, (or if you use numeric IDs, you could have many more categories). The former is, IIRC, faster, but more work to implement. Whereas the latter two are very fast to implement but somewhat slower to query. For the last two cases the MySQL function FIND_IN_SET() will be very useful. -- Richard Heyes ++ | Access SSH with a Windows mapped drive | |http://www.phpguru.org/sftpdrive| ++ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Categories like wordpress
it's the most flexible and fastest to query. Mmm, that's debateable. Not knowing the ins and outs of MySQL I'd hazard a guess that reading an extra 255 bytes from the table file might be faster in some circumstances than opening two extra table files. And I don't see why it's more flexible...? The latter two solutions I suggested are certainly easier to work with and (with todays hardware), speed isn't always a factor. -- Richard Heyes ++ | Access SSH with a Windows mapped drive | |http://www.phpguru.org/sftpdrive| ++ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

taking to too much time while inserting into the database.
The file's size will be more than 5000 lines.
Then i tried to build a string of ; seperated queries. as follows
for($i=1; $isizeof($array); $i++){
$insert_string .= insert into tablename (v1, v2. v6)
values('$array[$i][1]', '$array[$i][2]'. '$array[$i][6]');;
}
if(!empty($insert_string)){
mysql_query($insert_string, $conn) or die(query failed : .mysql_errror());
}
Its throwing error saying check the manual for right syntax.
After investigating in some sites i come to know that its problem of
limitations in query size.
I also tried with SET GLOBAL max_allowed_packet=3000;
Then also its throwing the same error.
Can anybody tell me how to fix this error and reduce the inserting time with
a single statement instead of writing more insert statements
You are probably looking for something like this.
?php
if ( count($array) ) {
$insert_string = INSERT INTO tablename (v1, v2. v6) VALUES ;
$data = array();
foreach ( $array AS $row ){
$row_clean = array_map('mysql_real_escape_string', $row);
$data[] = ('{$row_clean[1]}', '{$row_clean[2]}',.'{$row_clean[6]}');
}
$insert_string = join(', ', $data);
mysql_query($insert_string, $conn) or die(query failed : .mysql_errror());
} else {
echo Nothing to insert;
}
?

Not knowing the ins and outs of MySQL I'd hazard a guess that reading an extra 255 bytes from the table file might be faster in some circumstances than opening two extra table files. And I don't see why it's more flexible...? Good point, I should have said can be more flexible and faster to query. I've found that every time I try to do something like this without having a mapping table that I eventually end up wanting to move to the mapping table setup. Of course that might just be because I'm so used to doing it that way. Certainly that doesn't mean that other solutions are wrong or bad in any way. I need to learn to not speak in absolutes. :) The latter two solutions I suggested are certainly easier to work with and (with todays hardware), speed isn't always a factor. Yes, another great point.

That would work, but will probably result in a query string that is too long.
I'll redo the above to fix that.
?php

$break_at = 100;
# Initialize the counter
$cnt = 0;
# Initial insert string
$insert_string = INSERT INTO tablename (v1, v2. v6) VALUES ;
# if there is data, then process, otherwise skip it.
if ( count($array) ) {
$data = array();
# Loop through data
foreach ( $array AS $row ) {
$cnt++;
# Clean the result data
$row_clean = array_map('mysql_real_escape_string', $row);
# Build data string and push it onto the data array.
$data[] = ('{$row_clean[1]}', '{$row_clean[2]}',.'{$row_clean[6]}');
# Break and insert if we are at the break point
if ( $cnt === $break_at ) {
# Reset Counter
$cnt = 0;
# Run insert
mysql_query($insert_string . join(', ', $data), $conn) or
die(query failed : .mysql_error());
# Reset data array
$data = array();
} //if
} //foreach
# This should take care of any extra that didn't get processed in the foreach
if ( count($data) ) {

Wouldn't using LOAD DATA INFILE be better than writing your own script?

Re: [PHP] check if any element of an array is not empty

hi,
as a result of one calculation I'm receiving an array where elements
could be 0 or date (as string -mm-dd hh:ii:ss).
I have to check if any of elements of the array is date or if all

If I try array_sum($result) I'll get 0 no matter what (0 + $string = 0).
I know I can do something like:
foreach($result as $value)
{
if ($value !=0)
{
$alert = true;
}
}
or
if (in_array($result, '-'))
{
$alert = true;
}
but I was thinking if there is the function does that.
thanks for any help.

You can create an empty array and check to see if the difference via
array_diff.
Cheers,

Ryan S wrote: Hey, Am not really used to using the JOIN in SQL so am a bit confused as to what kind of data I need to enter into this table: image_category_mapping table: - image_id - category_id It comes down to database normalization (http://en.wikipedia.org/wiki/Database_normalization). The idea behind database normalization is you only ever have one copy of the data, you don't have to update multiple tables to reflect a change. So you only store the image in the 'images' table: create table images ( image_id int auto_increment primary key, image_name text, .. ); For multiple categories to share a particular image, there needs to be a link between a category and an image. If you only ever want one image per category, you could put the image_id in the categories table: create table categories ( category_id int auto_increment primary key, category_name text, image_id int, . ); However the problem with that is if you want more than one image, instead of adding another field to the categories table: create table categories ( category_id int auto_increment primary key, category_name text, image_id int, image_id_two int, . ); which means if you want a category to have 3 images, you need another field and so on, so instead you create a separate table: create table category_images ( category_id int, image_id int ); which means you could have 10 images for that category and no db changes are necessary. So you create the image as normal (insert into images ...). Then when you link it to a particular category, you insert into the separate table: insert into category_images (category_id, image_id) values (.); This also means if you update the image (eg change the name or alt-value or whatever), it's automatically reflected for all categories. How do you get an image for the particular category? SELECT i.* from images i INNER JOIN category_images ci ON (image_id) WHERE category_id='X'; That will give you (multiple if necessary) images for that category. -- Postgresql php tutorials http://www.designmagick.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
