RE: [PHP] Purpose of $$var ?????
variable variable... right up there with array array
basically what you are saying is resolve $var, then find out what that variable
holds
example;
assume your $counter is currently at 5
$var = v.$counter._high_indiv;
would mean that $var= v5_high_indiv
assuming that v5_high_indiv is dynamically assigned somewhere as a variable
$$var is the value of $v5_high_indiv
make sense?
variable variables are especially good in loops... for example, if you have
variables called
$user1, $user2, $user3
to print out all the variables would require one line per variable (and alot of
typing). using variable variables you could print out the value of all users by
looping it
for($i=1;$i100;$i++){
$user=user.$i;
echo $$user;
}

Subject: [PHP] Purpose of $$var ?
The script was working great before PHP 4.2.x and not after that. So, I
looked through the code and came upon this variable, $$var. I have no
idea what the purpose of the double $ is for a variable. Anyone know?
--clip--
$var = v.$counter._high_indiv;
$val3 = $$var;
--clip

Well, if you RTFM, you'll know that file() returns the file in an array ...
with the newline still attached. So one possible solution is after using
file(), loop through $users and remove the trailing \n.
thanks, I am/was looking to avoid looping through the array unnecessarily, and

Then use:

leaving that last user added to the file not to match since it will not have a
\n at the end of it...
adding one to the user as it is added into the array results in yet another
array element after the file() since it reads the additional line as another
array element.
BTW, it should be:
fwrite ($fd, join('', $users));
otherwise each time you write the file out it will have an increasing number
of \n attached to each user.
thats the crux...
fwrite ($fd, join('', $users));
results in a long string of usernames in the, which can't be grabbed back into
the array with the file... in short, there is no way to trim as you file() to
eliinate this (from what i can see) other than running it through each() or
something and rebuilding the array after trimming. Was hoping for something a

RE: [PHP] file() and array values contain extra \n
Start from scratch. You have a file with a single user on each line: tom\n dick\n harry\n You use file() to read into array $users. You compare as in above. You add a user by: $users[] = NEW_USER\n; You write out the file as above. curious... when I ran through that (before posting initially) was getting the following from print_r of the file() results... Array ( [0] = admin [1] = user1 [2] = user2 [3] = user3 [4] = ) which lead me to believe that the last \n was parsing as an extra element in the array... (not sure why), thus the dilema of either trimming each element of the array, or pop'ing an element off the end of the array. both seemed annoying, thus the post after recoding it with each/trim into new array and use that for checking validity... I redid the original file using the script and got different results; Array ( [0] = admin [1] = user1 [2] = user2 [3] = user3 ) which is what I expected in the first place... as such, the original code could now just check for the username with a .\n on the end (as you recommended). Futsed up there somewhere... thus the seemingly stupid question. cheers, Dave -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

RE: [PHP] Paying Job...
I have never charge by the page simply because I don't want to be limited in my design. Also, I don't want them saying I've added unneeded pages to up the price. or have customers nitpicking about removing pages to cut costs... I don't know how you would charge by the script since you should be using object oriented code. Wouldn't this be similar to charging by the page? how much code is original these days either... we have a collection of snippets for just about every instance... perhaps only charging the a quarter of the value of the development for an app, but rehashing the code for several other lcients cutting down on development time. So that leaves hourly or by the project (not mentioned). Personally, I like to do it by the project, although I am probably a minority in my preference. By the project gives the client a nice set price. However, the scope has to be extremely well defined. It should be anyway, but thats the trick... otherwise the simple aplpication will in teh customer eyes include this, that, and the other thing, despite the 30-50 hours that adds to the developemnt. You can't overstate the boundries of deliverables in a contract. more so if charging by the project. I then charge by the hour for requests outside the original scope, which happens all the time. It also keeps them in check on their requests. Depending on the client, I require a third or half up front for a project. good form. Always build in some slush factor as well... clients ask for minor this and minor that... if you have built in some slush, you can give them those without additional cost. the more they beat you up on the contract price, the more slush you remove, and make them aware that its all fine, but every little extra will have to be charged now since theve removed your flexibility. Look at it like you aren't doing the development, you are outsourcing it... what is going to ensure that at the end of the project you have enough to pay your developer plus posket a few bucks.

[PHP] regex match problem
as part of a larger application we have a bit of code that processes whois to
determine domain name expiry dates. Most formats are easily parsed, but
Register.Com has thrown the little regex for a loop and I am unsure as to a
clean workaround.
Here is what we have;
...
$pregmatchstring=/([\s])*(Renewal\DDate|Registered\sthrough|Expires|Record\sExp
ires|Domain\sExpires|Expiry\sDate)([\D\s]*)(.*)/i;
...
exec($command,$cresult,$cstatus); # puts all lines into array
$expire='';
for($i=0;$icount($cresult);$i++){
if(preg_match($pregmatchstring,$cresult[$i], $matches)){
$expire.=strtotime(trim($matches[4],. \t\n\r));
}else{
$expire.='';
}
}
...
This regex handles pretty much everything...
/
strip space characters from the front (some indent)
([\s])*
identify the exipery date line from other verbose entries containing expir
or similar
(Renewal\DDate|Registered\sthrough|Expires|Record\sExpires|Domain\sExpires|Expir
y\sDate)
any other spaces, .:, or other verbose crap afterwards **except for
numbers**
essentially grabs everything else up to the first number
thought I was being slick with this one
([\D\s]*)
grab numbers/date - gets the 2002/12/01, 09-APR-03, 2002-08-19 00:00:00.000
(.*)
and make case insensitive
/i
takes care of
Renewal-Date: 2002/12/01
Registered through- 08/16/02 00:00:00
Expires on: 09-APR-03
expires: 2003-01-17 02:16:03
Domain expires on 03-Apr-2003
Record expires on 2002-08-19 00:00:00.000
Record expires on 29-Mar-2003.
Record expires on 2003-03-25.
DOMAIN EXPIRES : 2003-03-25.
Expiry Date..2003.03.25
HOWEVER... this simple solution breaks for register.com because of their date
format
Expires on..: Tue, Jul 29, 2003
because the regex only returns 29, 2003 as the date which barfs for the
strtotime()
not the regex fault of the strtotime fault, as they are doing what instructed...
Any ideas on a way to simply overcome the register.com format and still keep a
simple all inclusive regex for all registrars?
Thanks

$body .= \n\n$cookiestr\n\n;
mail($to,$subject,$body,$from);
exit;
}
Well, I recieve a mail, but the mailcontent is empty.
The cookie string is written to a hidden field like this:
document.write('FORMINPUT TYPE=HIDDEN NAME=\comments\

so your cookie variable name is cookiestr
why use Javascript, and not just

RE: [PHP] Automatic include of files containing functions
I don't know about the efficiency .. but to do it .. you can use
function_exists() to see if a function is already defined if not include the
file for that function before using a function.
Please check this for viability...
# the directory ./includes/ contains
# - get_my_info.php containing the function get_my_info()
# - and numerous other functions which may or may not be
# needed by any particular file
#
# include at the top of each page
# function_do(FunctionName,FunctionVariables)
function function_do($f_name,$f_string){
if (!function_exists($f_name)) {
# function doesn't exists, needs to be included
require('./includes/'.$f_name.'.php');
} else {
# function already exists, no action required
}
eval(\$return=$f_name($f_string););
return $return;
}
/*
...
*/
# when we need to run a function
# instead of...
$my_info = get_my_info('name','account');
# we would do...
$my_info = function_do(get_my_info,'name','account');
This would check to see if the function was already called and included, and if
not, include, then run and return the result. this would avoid having to
include explicitly any files containing functions on any page as they would all
be loaded dynamically.
Am I groking this correctly?

RE: [PHP] Can PHP do this...?
John, PHP-general,
OK. I think I understand this, but let me ask just to be sure.
So if I setup in my page something to this effect:
if ($_SERVER['!HTTPS']) {
echo Switching over to SSL...;
echo META redirect to SSL;
yuck
recommend insuring this is at the top of your page and using header() instead
appears seamless to the client
} else {
echo **Rest of Page**;
}
and would eliminate that as well
-Start of file--
?PHP
if ($_SERVER['HTTPS']!='on') {
header(Location: https://www.example.com/page.ext;);
exit;
}
# rest of page here since if it isn't secure the page stops at the exit after
the header has been sent to the browser to redirect.
?
-end of file--
Check your particular server response for the match, you may be able to just do;
if (!$_SERVER['HTTPS']) {
Cheers,

RE: [PHP] Automatic include of files containing functions
Here is what I am looking at for a partial solutions (see redirect missing
function error for my next hurdle)...
All functions are contained within individual files in a functions directory,
none of which are hard included into the PHP pages;
eg//
./functions/ShowThis.php
./functions/ShowThat.php
./functions/ShowOther.php
in each PHP page...
?PHP
function func($f_name){
if(!function_exists($f_name)){
require('/path/to/functions/'.$f_name.'.php');
}else{
# function already exists, no action required
}
return $f_name;
}
?
Now when we want to call functions, we use the following syntax...
instead of;
$MyInfo=ShowOther($someVariable);
we use;
$MyInfo=call_user_func(func('ShowOther'),$someVariable);
This seems to accomplish what I want which is to remove my large 30 function
text file from being loaded for every page when some pages only require one of
the functions in the file.
Comments?

error_handler case(missing_function){
require('/path/to/functions/'.$missing_function.'.php');
return/retry the function or line of code
elseif file doesn't exist
terminate with helpful info... can't find function in functions dir...
}
/pseudo code
in short, soe code to drop in the header of each document to remove the
requirement to have any functions hard coded into the pages, and simply have a
repository of functions in a directory that would be included only when called.

RE: [PHP] Dynamically generate a drop down list
Is it possible to have a function which echoes the values as they are
read from the database?
something like
function init_auth_list()
{
print select name=author option value=\\select the name of
the author/option\;
$query=select name from author order by name;
$result=pg_exec($GLOBALS[db],$query);
$numrows=pg_numrows($result);
$i=0;
while($i$numrows)
{
$row=pg_fetch_row($result,$i);
print option name=\.$row[0].\$row[0]/option;
$i++;
}
print /select;
}
Two things with this, and opinions may vary...
Functions shouldn't print or echo anything, rather you should return what is to
be displayed. Also you may want to clean up/condense your while in the
following manner;
?PHP
function init_auth_list(){
$return=select name=author option value=\\select the name of the
author/option\;
$query=select name from author order by name;
$result=pg_exec($GLOBALS[db],$query);
$numrows=pg_numrows($result);
# $i=0; moved to while statement
while($i=0;$i$numrows;$i++;){
$row=pg_fetch_row($result,$i);
$return.=option name=\.$row[0].\$row[0]/option;
# $i++; moved to while statement
}
$return.=/select;
return $return;
}
?
then print your select box with the following
?PHP echo init_auth_list(); ?
much of that is personal preference mind you;

we have a number of csv dumps that occasionally have to be used to update tables in a postgres database... normally this is done by uploading the file and whomever running a php based parser which opens the file into an array via file(), does a split() on the comma, then executes an insert or update to the database with the split array values. we have a new upload that involves a 143mb file, compared to previous upload sizes of 10k to 150k. Is there a more efficient way to handle this rather than having PHP load the entire file into an array (which would have to be in memory during the operation, correct?). Perhaps fopen and reading line by line, or would that be the same load? thanks Dave -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] best method to resize images
have a situation where clients will be uploading images via a web interface. We need to process these images to create thumbnails. In the past we have used image but have found that the output is somewhat less than desireable and limited to jpg. We would like to be able to soften the image prior to resize so it is a little clearer in the thumbnail, as well as have the option of working with gif, png, etc... Comments appreciated.

[PHP] timing out exec statements
we are dropping to a perl script to process transactions, occasionally the remote server the perl script interacts with becomes bogged, the transaction goes into limbo, or for whatever reason the processing of that transaction hangs (happening about 0.2% of the time). Is there a way to time and timeout the exec statement... just assume it has failed, ditch the execution, and handle the failed transaction after X seconds? The alternative we have is to run the exec and redirect the return results to another script so that no single exec would graing the whole master php script to a halt. thoughts?

[PHP] fsockopen - returning results from port 80, 8080 and 443 requests
Creating a quick script where we can poll the services on a particular server to
verify if they are running or not. this will be included in a larger scope
application once the details are worked out.
Am having a problem getting results from queries to web server ports though.
Port 80(std), 8080(FP), and 443(SSL) either timeout without returning any
results, or error with some of the other attempts at illiciting a response that
we have tried (like specifying ssl:// prior to the hostname).
Code and two smaple outputs below. Thoughts?

RE: [PHP] Warning: Invalid argument supplied for foreach()
Hi all,
I am getting crazy, can't understand what i missed!
Does anybody know?
$champs = array (titre_art = h3 ,nom = bleu, prenom = green,
resume = bold);
foreach($champs as $key = $value) {
echo td class='$value'$row($key))/td;
}
never used foreach()... but I would check the following:
$row($key)) = appears to have an extra ) though it would just be printed in
your example
$row($key) = if it is an array reference, should be $row[$key]
Here is another way to do your problem though
while(list($key,$value)=each($champs)){
echo td class='$value'$key/td;
}

[PHP] scoring/sorting db search results based on score
looking for code snippets or links to examples of the following; - Have a database with multiple fields that will be searched against (happens to be PostgreSQL in this instance, but we can migrate any MySQL based examples/code) - We wish to score search results - ie: a match in keywords is worth 5 points, title worth 3, and description worth 1, perhaps even so far as multiple matches producing multiples of the point value(though that can be a later consideration) - Once we get the results, we would want to display in the order of the scoring, most points first etc... Obviously there are convoluted ways to accomplish, but I am looking to maximize the database performance, limit the number of recursive searches, and use the database/PHP each handle their portion of the search/score/ranking based on their strengths and use of system resources. appreciate any feedback Dave -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] scoring/sorting db search results based on score
Appreciate the responses... Try SELECT , (((keywords LIKE '%$search%') * 5) + ((title LIKE '%$search%') * 3) + (description LIKE '%$search%')) score FROM . ORDER BY score DESC PostgreSQL cannot type cast the Boolean type so you have to use a case statement, also changing like to ilike will get results regardless of case. SELECT , ((CASE WHEN (keywords ILIKE '%$search%') THEN 5 ELSE 0 END) + (CASE WHEN (title ILIKE '%$search%') THEN 3 ELSE 0 END) + (CASE WHEN (description ILIKE '%$search%') THEN 1 ELSE 0 END)) AS score FROM ORDER BY score DESC We are talking a db of under 10k records where the search would take place on. what are the ramifications of this as a load on the postgres server? Wouldn't want to have a great search query that grinds the server to a halt everytime someone searches regardless of the accuracy of the end result :) Thanks Dave -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] register_globals per virtual host
a while ago we upgraded the php installations on our servers. for a quick fix we set register_globals to on for code compatibility. Since then we have been cleaning up code to eliminate this. We likely still have some virtual hosts who are using these globals though, so while we are wanting them to modify their code, we wish to turn globals off for the rest of the server, and allow those sites to be the exception to the rule. Assumption is that adding a php_admin_value register_globals on to selected virtual host containers in apache will allow that particular site access to the globals while allowing the default (off) for the remainder of the sites. Is the assumption correct? Ramifications or caveats that should be considered? Dave -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Call to undefined function: xml_parser_create()... but CGI compiled --with-xml
a production box running 4.2.2 recently had a script added to it requiring use of xml functionality. The box was already compiled (a few versions earlier) with the --with-xml option. Since then, have upgraded this box twice (though it is due for another) using config.nice to ensure the same options are installed. have configured this as an apache module and as the CGI... the apache module uses the XML functions just fine. The CGI however gives the error in the subject. Have compared phpinfo() on each, and added extension_dir and include_dir to the standalone php's php.ini so that it matches the apache module version, still no joy. Any thoughts, recommendations, or hints as to what I may be missing which would cause the cgi version not to compile with the xml features even when the --with-xml option is and has been specified since 4.0.x and through every upgrade since then thanks to using the same config.nice. thanks Dave -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
