[PHP] When to call mysqli::close
Hi good people,
When should i call mysqli::close ? Should I call $stmt-close() at the end
of the method(below) . Or should I call it after every condition ensuring
that I close the database connection even if the process fails at some
stage e.g bind param
public function function_name($id,$new_id ){
$query = UPDATE TABLE SET name = ? WHERE field = ? ;
if($stmt=$this-prepare($query)){
if($stmt-bind_param(is, $id, $new_id)){
if($stmt-execute()){
}else{//Could not execute the prepared statement
$message = Could not execute the prepared statement;
}
}else{//Could not bind the parameters
$message = Could not bind the parameters;
}
}else{
$message = Could not prepare the statement;
}
return $message
}
Kind regards
Albert Kamau

Dan [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] You really need to filter your input more, have a list of what is acceptable not what is unacceptable. That being, make it a requirement that the url input has a TDL(.com, .net, .org, etc.) or is a valid IP(ping it), only allow alphanumerics for the name, etc. When you don't validate your site can get hacked, I know it's not really insecure but it's just an example of input you may not expect, if you try to validate http://localhost it goes ahead and validates your server's html. I make sure it starts with http: or https: and change spaces to %20 so it will work. I also check for some possible recursion issues. I think I'm fairly secure just doing that. What could happen security wise? What else do you think I need to do? I don't want to check for a TLD as there are many and I don't think it is necessary... and pinging doesn't seem like a good idea either as some servers probably won't respond to pings. The localhost issue is interesting, but I don't see it as a security issue. I would like to know if there are any serious secirity issues I may be overlooking though.

You could always make it a function...ie:
function drawTableRow($sqlRow) {
return tr\ntd class=\tabletext\. $sqlRow['time'] ./td
\ntd class=\tabletext\.$row['field']./td; // Simplified
for time purposes.
}
// Execute the query
foreach ($row = mysql_fetch_array($query)) {
echo drawTableRow($row);
}
That's perfect. I should of thought of using a function.

Good suggestion. I like heredoc's clean presentation:
__
function drawTableRow($sqlrow)
{
return _
tr
td class=tabletext{$sqlrow['time']}/td
td class=tabletext{$sqlrow['field']}/td
td class=tabletext{$sqlrow['division']}/td
/tr
_;
}
__
By the way, if every cell in every row is class tabletext why
have a class at all? You could simply apply the desired styles to
the td element.
Regards,
Paul
I'm using heredoc elsewhere on the page so that's a good idea.
As far as the CSS on the td, other cells in the table have
different styling.

BTW - for what I'm trying to do at the moment, if I change the first

$myFilter = new InputFilter();
it takes care of the Notice problem.

This works for me, simple and easy.
// Grabs current Year

for($year=$year; $year = $yearEnd; $year++) {

Thanks. This was close, but it didn't account for the first option
being last year. I edited and ended up with this which works.
// Grabs current Year
$year=date(Y);
$yearFirst = $year-1;
// Number of years you want total
$yearEnd=$year+2;
// Generate Drop Down
echo select\n;
for($year=$yearFirst; $year = $yearEnd; $year++) {
print option value=\$year\$year/option;

If you really want to keep the p?name syntax, I would suggest
throwing
them in an array with keys.
$arr[p1name]
$arr[p2name]
Then that way you can create the key dynamically:
$arr[p.$i.name]
Not pretty, but it works.
Thanks,
I haven't checked this, but couldn't you reference it as $arr[p
$iname]
? Is there a reason why variable expansion wouldn't work in this
circumstance?
If it does, you could make it easier to read by doing $arr[p{$i}
name]
even though the {} aren't required. It'd be a lot easier to read than
concatenations :)
Regards, Adam.
Both of those ways work. I think there's a question on the PHP
Certification
Exam about the different ways to work with strings.

RE: [PHP] this line throws up an undefined index.
Ross wrote: ? $filename = basename($_SERVER['SCRIPT_FILENAME']); $link= ../text_only/$filename; ? any ideas how to prevent this error? From the PHP Documentation: $_SERVER is an array containing information such as headers, paths, and script locations. The entries in this array are created by the webserver. There is no guarantee that every webserver will provide any of these; servers may omit some, or provide others not listed here. That said, a large number of these variables are accounted for in the » CGI 1.1 specification, so you should be able to expect those. If you are executing a script on the command line it will not exist. Try using argc and argv for that. The filename is typically argv[0]. isset($_SERVER['SCRIPT_FILENAME']) will return true if the index exist. Albert -- No virus found in this outgoing message. Checked by AVG Free Edition.

Yes you are correct.
Why don't you include the file? PHP will parse the PHP inside it and output
the HTML...
If you want to get the contents into a variable then do something like:

include(file.html);

It also has an information page displaying information about the three images which also updates every time the image changes. Maybe you shouldn't do that... Stretch it out to 10 seconds and see where your load goes. At 10 seconds all the problems disappear. Unfortunately the customer requires this to update at least every 5 seconds. Find out which of the 5 sessions is most expensive (slowest). Can you cache the results of that one? How about the second slowest? Can you cache ANYTHING to make the application faster? I am now busy converting the three images and info page to use a cached copy if they have not changed. Does anyone have an idea of what I can do (short of recoding)? #1. Buy more hardware, and build a server farm. On the lowest end of the spectrum (up to 5 simultaneous users) I have to make it work on a Celeron 400 with 512MB RAM. At the highest end (up to 100 simultaneous users) I have a Dual Xeon 3.4GHZ with 2GB RAM and SCSI drives. #2. Buy the Zend Cache Will probably to that for the top end machines. The Zend Cache costs more than my lowest end machine after assembly. #3. Install some other Cache product (most of which aren't as good/fast/solid as Zend Cache, imho) I tend to trust Zend a bit more than the other developers (maybe because PHP is based on the Zend engine).

We have made some changes to our PHP application and now the machine is having trouble serving the pages. Apache is occupying almost 90% CPU usage. I have resolved this issue by removing a piece of code which reads a set of parameters from a database. It seems that the hard disk on the machine is quite slow, slowing down all database access with it... I now check if the parameters are set in the session, if it is I use them otherwise I read them from the database and save it as session variables. When it changes I simply remove it from the session so it forces an update. So far it is working quite well. I now want to go and take all the static stuff that the user will configure once in a life time and put it in the session and only update it when it changes instead of reading it from the database every five seconds or so. For this I don't want to use a disk based session handler. I want the session variables to remain in memory (about 20KB per user) as to speed up the whole process. I also want an opcode cache to cache the compiled pages on the server in an attempt to speed up the HTTP server. For this I wanted to use mmCache (actually I want to use Zend Performance Suite but first I need to prove that it is worth $ 1000 per CPU and from the stats on the mmCache site mmCache is faster...) but it seems that the mmCache project has been abandoned as there have been no work done on it since 2003.

An alternate method, which I found to be more reliable, would be to put the database files in a tarball, transfer it to the new server and then extract the tarball into the database directory. I am running MySQL on a Linux server. The databases are in /var/lib/mysql. If your database is called db then there will be a db directory in /var/lib/mysql. Before making the backup you either need to stop MySQL (preferred) or flush all data to tables and make sure nothing is writing/reading to/from the database. To put it in a tarball: origin# cd /var/lib/mysql origin# tar cvf db_backup_20060112.tar db You then copy that db_backup_20060112.tar file to the MySQL data directory of your destination server and once it's there extract it again: origin# scp db_backup_20060112.tar [EMAIL PROTECTED] destination# cd /var/lib/mysql destination# tar xvf db_backup_20060112.tar You then might need to set permissions if the UID of your origin server MySQL user and destination server MySQL user is not the same. After starting MySQL server on your destination server you should have the database exactly like it was on the original. BTW you can transfer MySQL data files from a Windows machine to a Linux machine and vice versa without any issues. There is a note in the MySQL documentation of the formatting your Windows server should use (to do with case sensitivity) HTH Albert -- No virus found in this outgoing message.

Convert your timestamp to a unix timestamp (see mktime() function).
Use the value returned by time() to calculate the difference in seconds.
$age = time() - $tableTimestamp;
Divide by 3600 to get hours
I would also like to exicute a mysql stament that pasess the tables and
removes fields older than say 72 hours. how would i go about this . ?
Get a timestamp of 72 hours ago:
$olderThan72Hours = time() - (72 * 3600);
Convert to the same format as your timestamp column:
$timestamp = date('Y-m-d H:i:s', $olderThan72Hours);
Delete the records from the table:
mysql_query(DELETE FROM table WHERE timestamp = '$timestamp') or
die('Could not delete from table');

RE: [PHP] Setting cookie for two domains.
Shafiq Rehman wrote: How can I register a session or cookie for two domains. I want to maintain logged user's state when he goes from one domain to other domain. My Sat TV provider uses something like what you want to allow me to navigate through their website and the websites of different channels without having to login on each website. Basically how I think they do it: - They have a database with the subscriber information which is shared by all the sites. - When you login, a popup window open (if popups are disabled it happens in your main window) which jumps from domain to domain and set the cookie with your session id. - When you logout the database does no longer contain the session id. The cookie is still set but the site checks the validity of the session id and if it is not valid anymore then you have to login again. So basically: After login you set the session cookie then open a page on the other domain passing the session id to it with GET / POST. That page sets the cookie for that domain and sends the user on in the process. When you logout you can then unset the cookie on the domain and open a page on the other domain to unset the cookie or simply invalidate the session id in a database. If you do this you need to check if the session id is still valid when you open a page. The actual session data should then be in a database (or similar) accessible by both domains.

In Mozilla it takes 5 seconds to display test3.php. When I put that frame at the top it displays immediately. If I put it in the middle it displays immediately. What I do remember is that when I download multiple files (using IE or Mozilla on WinXP) from the same server I can only do two downloads at a time. I don't know if this is an OS setting. I did found a setting for IE and changed that value to 5 so now I can download up to 5 files from the same server at the same time. Don't know where to change it in Mozilla. It therefore seems that the browser makes a connection to the server for the first page and starts downloading it. At the same time it makes a connection to the server for the second page and starts downloading it. After one of these two have downloaded it start downloading the third page. If you change the setting in the browser (like I did with IE) you can download up to that number of pages at the same time. It is therefore not an issue with PHP but with the browser.

If I do not set imagealphablending ($im, true) then the transparency in the top image is ignored and I do not see the satellite image.

Notes: 1. When using imagecreatetruecolor the images turn black 2. When using imagealphablending = true or imagealphablending = false with imagecopy the result is the same. The top image is shown but it is almost transparent. Some images are also discoloured. 3. When using imagecopymerge to copy with a pct value of 99, and commenting out the imagealphablending line the top image does not appear at all 4. When using imagecopymerge to copy with a pct value of 99, and imagealphablending=true, it has the same result as 2. above. 5. When using imagecopymerge to copy with a pct value of 50, and Imagealphablending=true, it has the same result as 2. above. What is the effect of the pct value of imagecopymerge? Should I be using different values for the pct value of imagecopymerge or is there an alternative method which will do what I want to be done?

Does anyone have any idea as to why this is happening?
You didn't specify but I guess all your databases are on the same server.
When accessing multiple databases on the same server using multiple
instances of a class, you need to make multiple connections to the server.
By default PHP creates only ONE connection to a server and the database you
select is linked to the connection. So instantiating another instance will
use the previous established connection and change the database.
To force a new connection, you need to use mysql_connect() instead of
mysql_pconnect(). When using mysql_connect() you can specify:
$this-dbh = @mysql_connect($db_host, $db_user, $db_pass, true);
[quote from=PHP manual]
resource mysql_connect ( [string server [, string username [, string
password [, bool new_link [, int client_flags ] )
[/quote]
Which will force a new connection. By default PHP will use a connection
which have already been established.
Take care when doing this as each time you instantiate a class a new
connection to the database will be created adding additional load on your
database which can cause a denial of service.
I normally store a list of connections to servers and databases in a
variable which can be accessed by the script. Every time I instantiate a new
instance of my database class I first make sure that a connection to that
server and database does not already exist. If it does exist then I call
mysql_connect() without the true for new_link otherwise I call
mysql_connect() with the true for new_link.
The downside of this is that you do not have persistent connections which
last beyond the end of the script.
Hope it helps

[PHP] Nested IFs Problem
I have the following nested ifs:
if ($row['date'] '2005-10-02') {
if ($row['time'] '12:00') {
if ($row['field'] == 'P5' ) {
echo td class=\tabletextbluebg\Success;
}
}
}
else {
echo td class=\tabletextred\Failed;
}
/td
Whenever the 3 if statements are true, I always get the correct
Success to echo. However, if any or all of the if statements are
false, I never get Failed to echo.
I know it's something simple, but I just can't see it at the moment.

Once the first if statement is evaluated as true, the else
statement will never be executed -- regardless of the outcome of
the two nested ifs. I am not sure what you are trying to accomplish
here, but perhaps all three of your if conditions should be
combined into one if condition ANDed () together? Or maybe the
if...elseif...else structure is what you need.
Hope this helps.

Re: [PHP] Validating Dynamic Checkboxes
Jason,
You lost me on this go around. I don't understand how we got from the
following function to your new verson:
//loop through records
$id = $row['id'];
$counter++;
if ($counter 1) {
$jscondition .= || document.getElementById('ed . $id .
').checked;
} else {
$jscondition .= document.getElementById('ed . $id .
').checked;
}
}
?
SCRIPT language=JavaScript
function validate() {
if (!(?php print $jscondition; ?)) {
alert('Please check at least one edit checkbox before submitting this
form.');
return false;
}
}
/SCRIPT
Remember that the above works insofar as it throws up the javascript
alert, but then submits the form anyway. I don't see how your new
function incorporates the loop to build $jscondition.
Thanks for any further input. I think I need to get some sleep.

It can't be done that way because the brackets have a different
meaning in Javascript syntax. You need to quote the whole name.
You may want to take a look at the example that comes with this forms
generation and validation class that supports the exact same type of
validation that you want:
http://www.phpclasses.org/formsgeneration
Hi Manuel,
I'm not certain I understand what you mean by quote the whole name.
Also, there are a lot of files in the formsgeneration class. Which one
has the example you are referring to?

[PHP] Regex (Phone Number)
I have been struggling with a javascript regex validation for U.S.
phone numbers all afternoon. This is part of Manuel Lemos' Formsgen
class. This is limited to the 7 digit number sans 3 digit area code. To
be complete, the regex should disallow a phone number that begins with
0 or 1, 555 or any digit followed by 11. Here is the regex I'm using:
^(?!\d[1]{2}|[5]{3})([2-9]\d{2})([-])\d{4}$
Manual Lemos indicated to me in an offline post that this should throw
a javascript runtime error because of the (? at the beginning of the
regex. I have tested it in over a dozen different browsers (Windows and
Mac) and the only one that throws the runtime error is IE on the Mac.
All others catch the errors I am trying to trap for with no runtime
errors. Can this regex be improved on or do I have to live with the
idiosyncratic behavior of Mac IE?
Thanks.

I'd make two tweaks, actually. First and most obviously, you're not
selecting *which* fname field to pass to your update query, so this
needs to be:
$query = UPDATE ref_events_reg
SET fname = '{$fname[$id]}'
WHERE id = '{$id}';
(By putting just $fname there, you are telling PHP to insert the
string representation of the whole array -- and the string
representation of any array is, er, exactly Array! ;)
This change may give you a clue to my other tweak -- I'd explicitly
set the indexes of all the fname[] fields to be sure they sync
correctly to the related check box, thus:
input type=\checkbox\ name=\ed[{$row['id']}]\ value=\Y\
input type=\text\ name=\fname[{$row['id']}]\
value=\{$row['fname']}\
Cheers!

Mike,
Thanks for the tweaks. That solved the problem.

for ($i=0;$icount($del);$i++){
$query = DELETE FROM ref_events_reg WHERE id = '$del[$i]';

Echoing the query produces:
DELETE FROM ref_events_reg WHERE id = A
I've also tried the following:
$query = DELETE FROM ref_events_reg WHERE id IN (' . implode(',',
addslashes($del)) . ');
This one produces a warning:

and the following query:
DELETE FROM ref_events_reg WHERE id IN ('')
Both attempts fail to delete any records even though several records
are checked.

Sorry, same result. No records deleted. Echoing the query returns:
DELETE FROM ref_events_reg WHERE id = 'A'
However, the id should be an integer. A var_dump() returns:
array(2) { [del]= array(2) { [0]= string(2) 15 [1]=
string(2) 16 } [submit]= string(6) Delete }
Further, when I echo $del[0], it returns -- 'A' while $del[1] returns
'r'. Just $del returns 'Array'.
Still working on it.

change it to

//do query

Hello, I have some problems sending a form via POST. When I submit the form, I get the error of 'Page Not Found'. This happens in some Internet Explorer (all are v5.5, I think). The action form is ok (FORM action=http://www.domain.com/formprocess.html; method=post). It happens randomly. I've the type .html associated with the php engine. And I need to use the url of action in long format (http://.) Anybody with the same problem??

[PHP] Problem with gettext support - Solaris 2.7
Hi! When I try to compile PHP 4.0.4 as Apache module with gettext support, the gettext support doesn't function. But when I compile PHP as CGI, the gettext support works fine. Where is the the problem (other functions works fine in both case)? I use Apache 1.3.14 with DSO support, GNU gettext 0.10.35, Solaris 5.7 and I have compiled PHP 4.0.4 with gcc 2.95.2 and these options: ./configure --with-apxs=/usr/local/apache/bin/apxs \ --with-config-file-path=/usr/local/apache/config \ --with-low-memory --with-gettext=/usr/local Does anyone have faced with similar problem or have solution for it?
