Hi, Have a look at the "Received:" headers of each email. They are in reverse order. I.e. the one at the top is the most recently added. Take into account timezone differences too. 12 hours seems like a very long time for a delay. I suspect one of the receiving hosts in the chain employs greylisting, and the sending network employs many different sending servers (ie like Google) in a round-robin fashion. The greylisting server may not be configured to recognise the many different servers as one 'set'. All speculation of course ;) Feel free to send the headers off list and I'll take a look.

Hi,
Try adding some error checking before and after the curl_exec() call:
// Check for an error
if(curl_errno($ch)>0){
print "Error creating curl object: Err Number:".
curl_errno($ch). " ,Description:" . curl_error($ch);
}
// Execute request
$result = curl_exec($ch);
// Check for an error again
if(curl_errno($ch)>0){
print "Error executing query: Err Number:". curl_errno($ch).
", Description:" . curl_error($ch));
}
It may also be wise to increase your time out whilst testing, just in case.

Ian

Hi Curtis,
I am suffering from sleep deprivation due to a new family addition and I
fail to see how your code will prevent a malicious user from binding to
an IP that I do not want him to. It appears to be an example of how to
bind to an IP, not how to prevent it.
Could you please explain?

I am learning and using the CodeIgniter (CI) framework for my current project and, not wanting to leave myself vulnerable, I read posts on the CI forum on this topic, to find out if I could (or needed) to use prepared statements in CI.. and I read one forum thread where one dev shows how to hack the core system of CI so that it can use PDO (for prepared statements) instead of the built-in ActiveRecord (or "Query Bindings") which apparently rely on mysql-real-escape-string. In that thread, the debate goes back and forth, as it does in other threads.. and while the sentiment that prepared statements are better because they remove the need to keep being ahead of the char-escaping chase... I never did see any example of *how* mysql-real-escape-string fails. The only thing I ever read that does show mysql-real-escape-string possibly failing is in the example in this article: http://shiflett.org/blog/2006/jan/addslashes-versus-mysql-real-escape-string or rather an article referred to there, here: http://ilia.ws/archives/103-mysql_real_escape_string-versus-Prepared-Statements.html Hi, Please bare in mind that the above example uses the mysql object, not mysqli (the improved mysql extenstion). The above attack doesn't work in mysqli (at least not in my setup!). There is also the issue of which character set is used by mysqli_real_escape_string. To be sure issue the mysqli_set_charset() call after connecting to the db. With regards to procedure in MySQL, there is one gotcha that caught me out. There is no way to ALTER a procedure, you must DROP and reCREATE it again. This is fine in most GUIs such as Heidi SQL, as all the work is done for you, but you must realize that when you issue the DROP command it also DROPS any permissions you have on that procedure. So to alter a procedure you must DROP, CREATE and then re-create the permissions. If you have a replicated setup with multiple servers and multiple web sites accessing them, this can be allot of permissions to re-apply. In web programming (or any other sort) you must ALWAYS assume that any input is malicious. Using this principle you can then build secure applications. For example, the above article takes the $_POST input without any validation. In this case it is a username. On my sites I tell users when registering that their username can only contain certain characters. If any other characters are supplied I strip them out. I can then pass data to mysqli_real_escape_string knowing that there will be no multi-byte characters in there to trip it up. The same goes for other input, validate it all. There are built in functions to do this for you [1], or you can build your own. It is not just input to watch out for, you must also Escape your output to mitigate Cross Site Scripting (XSS)[2] and other attacks. There are many automated tools out there to help you test your applications. You wont know its breakable unless you try to break it! And if you don't, others will. I suggest you go to the OWASP site [3] (The Open Web Application Security Project) and have a look around.

Hi,
Found the problem:
Unix timestamps are a moment in time and so timezones have no influences
on them. They count the number of seconds since 1970-01-01 00:00 *UTC*
See: http://en.wikipedia.org/wiki/Unix_time
So the timestamp will always be the same no matter which timezone.
I will use by workaround to get the expected timestamp for use in
comparisons.

Ian

The format command returns different result if the 'U' for timestamp is specified. It also returns the same (wrong) result for DateTime::getTimestamp() as well. The clients are booking entry into a place at a specific time, for example 7am in Singapore on the 12 April. Clients can book right up to the entry time (if there is space available). I want to make sure they are not trying to book in the past. The booking system is in the UK but clients can book from anywhere. I cannot rely on them having the right time on their systems (or being in the right place). Plus this would mean relying on client supplied data, which is a no-no ;) I have previously used a gmt offset, which was good enough as there are not that many people who book close to the entry time. But now its time to improve this and use proper time zone info which can change without my input. If no-one can find a problem with my code I will submit it as a bug.

[PHP] DateTime using DateTimeZone Timestamp problem
Hi,
I have a problem using the php built in classes DateTime and DateTimeZone.
The idea behind the following code is to return the timestamp for the
current time in Singapore (or other places). What it actually returns
is the timestamp for the local system. Other formatted dates appear to
return correctly, which is why I am puzzled.
I am using the latest php 5.3.6 compiled from source on a OpenVZ CentOS
container. All packages are up to date.
Am I doing something wrong or is this a bug?
I can workaround this problem my parsing the correctly formatted date
using strtotime() but I would like to know what's going on.
This is the output of the script:
Current time in Asia/Singapore is 2011-04-04 23:32:36
Timestamp for Asia/Singapore is 1301931156
Date created from previous timestamp is 2011-04-04 16:32:36
The code is :
format("Y-m-d H:i:s")}";
# Print the timestamp
print "Timestamp for {$timezone} ";
print "is {$remote_time->format("U")}";
# Get the timestamp and create a date from it
$timestamp = (int)$remote_time->format("U");
# Show the formatted date created from timestamp
print "Date created from previous timestamp is ";
print date("Y-m-d H:i:s",$timestamp)."";

Hi,
I regularly use PHPMailer to send out a mailshot to two batches of 5
and had no problems at all.
I would not use BCC. Just set the recipient, send the email, then use
the ClearAllRecipients() function and start again.
We do other things like set a custom MessageID for tracking bounces and
auto unsubscribing during this process as well.
I also do this from the command line so I don't have to worry about
timeouts / apache memory issues etc. But as long as you're aware of
these problems then you can set the values appropriately.
Regards
Ian

You could have a php daemon running as root which periodically checks if the share needs mounting. The trigger could be many things, like the existence of a file or database record. You can then have the web site create the file or database record when it needs the share mounting and then wait for the mount to appear.

[PHP] Doing dynamic routing for an office
Hi, I have had a weird request as a project and that is to build a system where the clients can put down their office plans into a system and based on where you are in the buliding (either via defined kiosks or mobile dropdown filters) it will print out directions on how to get somewhere within that building. Now, to do it from a fixed location is okay - that could just be a manual input for each building, but for the variable start point I have no idea how to do it. To explain in another way: * You enter one of the clients offices - you walk up to the touch screen kiosk and say you are looking to go to Mr Awesomes office. The system then says, okay - head to the elevators on your right, go to the eighth floor, turn right walk to the end of the passage and the office is on your left. This part is easy - the following isnt. * You are new to the company. You are having a smoke break in a smoking room and remember you have a meeting. You logon to a mobile site from your phone (or from your workstation) and you are presented with some filtering options to pin point where you are (since we cant use GPS here), you then again say you need to go to Mr Awesomes offices and the system works out that you need to exit the smoking room left, second passage way right, first left, into the elevators, up 2 floors, right out the elevators and walk to the end of the passage and office is on your left. Any ideas how I could do this easily? The front end isnt a problem, its the processing behind it actually working out the route. Hope my description is clear enough and sorry if this has been discussed before - I have no idea what to search for :) Thanks Ian

Hi,
I have used this code to feed data to gpg and read back the encrypted
result, Im sure you can adapt it to your needs.
function Encrypt($data){
# http://www.theoslogic.com/scripts/php-gpg/
$gpg_command="/usr/bin/gpg $parameters";
$errLog = "/tmp/errors.log";
$dspecs = array(
0=>array("pipe", "r"),
1=>array("pipe", "w"),
2=>array("file", $errLog, "a")
);
$encrypted="";
$procdata="";
$gpgproc = proc_open($gpg_command, $dspecs, $pipes);
if (is_resource($gpgproc)) {
fwrite($pipes[0], $data);
fclose($pipes[0]);
while($procdata = fgets($pipes[1], 1024)) {
$encrypted .= $procdata;
}
fclose($pipes[1]);
}
return $encrypted;
}
It works really well.

Ian

Hi,
Instead of using php to work out the 30 days part you could just let the
database do it:
$sql = "SELECT DISTINCT restaurants.ID, name, address, inDate
FROM restaurants, inspections
WHERE restaurants.name != '' AND
CAST(inspections.inDate AS DATE)<=
DATE_SUB(NOW(),INTERVAL 30 DAYS)
GROUP BY restaurants.ID ORDER BY 'name' ";
You will have to check that the CAST function is working properly on your
varchar'ed date
fields before testing this query. It should point you in the right direction
though.

Ian

[PHP] require/include fails with APC enabled
I have one server that is acting up whenever I try to enable APC. PHP scripts execute normally as long as there are no calls to include(), include_once(), require(), or require_once(). Any file (no matter the size) that can be included while APC is disabled will cause the script to silently fail at the point of include when APC is enabled. There is no output in the PHP error_log, even when logging all message types. This feels like it's probably a really simple fix, but we're stumped. Any help you can provide would be greatly appreciated.

[PHP] Mastercard Securecode
Hi, A search of google has been unsuccessfull so I am posting here in the hope someone can help. We have recently been told that we must implement the Mastercard Securecode 'feature' for all our Maesto transactions or face fines of up $25000 per month. Our merchant has provided a SDK which has APIs in C, COM or Java (specifically the "Arcot Transfort Merchant Software"). We previously moved away from a Java API into our merchant in favour of a pure PHP implementation using XML and would rather not take a step back again. Is anyone aware of a pure PHP implementation of the Mastercard Securecode 'feature'? I am aware I can link into COM & Java from PHP, and even take the C API and make my own extension but I would rather not pursue these options unless I really have to!

Hi,
This is a quick function that works using unix time stamps. Its a bit quick
and messy but
works ok. Take a look at the manual page for the strtotime() function to get a
better idea
of what it can handle.
0,
"Hours" => 0,
"Minutes" => 0,
"Seconds" => 0
);
$amounts= Array(
"Days" => 60*60*24,
"Hours" => 60*60,
"Minutes" => 60
);
$difference = $Date2_UnixTimeStamp - $Date1_UnixTimeStamp;
if($difference >= $amounts["Days"]){
$return_difference["Days"] = floor($difference /
$amounts["Days"]);
$difference -= $return_difference["Days"] * $amounts["Days"];
}
if($difference >= $amounts["Hours"]){
$return_difference["Hours"] = floor($difference /
$amounts["Hours"]);
$difference -= $return_difference["Hours"] *
$amounts["Hours"];
}
if($difference >= $amounts["Minutes"]){
$return_difference["Minutes"] = floor($difference /
$amounts["Minutes"]);
$difference -= $return_difference["Minutes"] *
$amounts["Minutes"];
}
$return_difference["Seconds"] = $difference;
return $return_difference;
}
?>

Hi, Sounds like you need to use the GROUP BY functions of MySQL This SQL is probably wrong because I don't remember seeing your schema (and am too busy here to go looking!) SELECT LEFT(last_name, 1 ) as Letter, Count(bookID) as NumberOfBooks FROM books INNER JOIN GROUP BY Letter ORDER BY Letter ASC You will have to play around with that to get the right results.

Looks like there is a double quote ( " ) missing from the end of the $SQL
variable.
When building complex SQL queries for use in PHP I usually test them in the
mysql
command line client or a gui such as HeidiSQL first to make sure I am getting
the
expected results.
Also you could try printing the SQL statement to the web page to make sure it
looks as
expected.
You can try checking for a MySQL error within PHP by using these functions:
mysql_errno()
mysql_error()

Re: [PHP] Unique User Hashes
We dont have registration - its a once off vote anonymously using the hash in the original email. We dont want registration otherwise it would be much easier - but this was the best way I could think of without user registration :/ On Wed, Feb 18, 2009 at 9:05 AM, Chris wrote: > Ian wrote: > >> Hi, >> >> Yep it is backed by DB and i do record when they vote - but its still >> flawed in how to track unique users :) Thanks though - will continue to look >> further. >> > > Do you have to log in to vote? > > How are you stopping people from signing up multiple times? > > > -- > Postgresql & php tutorials > http://www.designmagick.com/ > >
Re: [PHP] Unique User Hashes
Hi, Yep it is backed by DB and i do record when they vote - but its still flawed in how to track unique users :) Thanks though - will continue to look further.

[PHP] Unique User Hashes
Hi, I am busy building an application that requires one time voting and to get around the user deleting a cookie that I set im keeping a hash on my side which I then try match before allowing anything. This is how I currently generate my hash: /* Get vars */ $browser = $_SERVER['HTTP_USER_AGENT']; $ip = $_SERVER['REMOTE_ADDR']; $real_client_ip = $_SERVER['HTTP_X_FORWARDED_FOR']; if(!empty($real_client_ip)) $name = gethostbyaddr($real_client_ip); else $name = gethostbyaddr($ip); /* Return generated hash */ return md5($browser.$ip.$real_client_ip.$name); Now thats not ideal because you can just change your user agent and vote again - but IP isnt good enough either because in South Africa due to the poor internet we all connect to international sites via a series of Transparent proxies which makes everyone seem to come from one IP. Anyone had to deal with this in the past and does anyone have any suggestions/ideas as to how I could better this setup? Many thanks in advance, Ian

Hi,
The MySQL syntax to alter a column is:
ALTER TABLE `table` MODIFY `column` BIGINT NOT NULL;
[ http://dev.mysql.com/doc/refman/5.1/en/alter-table.html ]
The sql statement
SHOW COLUMNSFROM `table`;
[ http://dev.mysql.com/doc/refman/5.1/en/show-columns.html ]
will give you a list of all the fields with there type, default values, null
etc...
You can then use this in the loop to find all the fields where null=NO.
Warning from the manual:
When you change a data type using CHANGE or MODIFY, MySQL tries to
convert existing column values to the new type as well as possible.
Warning
This conversion may result in alteration of data. For example, if you
shorten a
string column, values may be truncated. To prevent the operation from
succeeding if conversions to the new data type would result in loss of
data, enable
strict SQL mode before using ALTER TABLE (see Section 5.1.6, “SQL Modes”).
I don't think this will affect you but bare it in mind.
Regards
Ian

[PHP] new xampp server problem w/mail
hi I have been searching for a way to get the php mail function to work and have had no luck. I was hoping you could address my situation: I have a fairly new xampp install and I need to know how to get mail() to work. I would like to know tha simplest way possible to get the mail function to work. I guess the major problem is that my xampp install doesn't have an email server. please advise my what I need to do to get one for a linux box. Please keep in mind that I am a newbie and need detailed instructions for installing any software and configuring any files that may need altered in the server's configuration files such as php.ini etc... email me at linia...@yahoo.com if you can help. Thanks, Ian

Hi, Disclaimer: Without seeing the actual blog entry this is all guess work! Your code above seems to find the half way point in the raw text. This is all very well if you do not have paragraphs or other formatting code that can move text around once displayed. To overcome this you will have to try and detect the number of paragraphs (or formatting code) before the half way point and after it and try and move the Google Ad entry to accommodate this. This will involve trial and error to determine an algorithm that best matches your blog entries. Or you could go down the easy route and add some sort of marker (database entry or a tag of some sort) to each blog which indicates were the Google ads should go. Personally I prefer the later options as its probably easier ;) Regards Ian -- -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hi,
It may help to run the command 'dir' to see where the web server considers its
path to be:
The response will include the current path as well as a directory listing.

[PHP] returning array from commandline
Hi, I am busy developing a commandline tool that will, in certain cirumstances, return an array of information when called and im having a problem with this. The last part of my code looks like this: if(is_array($rslt)) return $rslt; else echo $rslt; I.e. if its an array dont echo it, return it rather and im have huge problems even using that $rslt variable. I have tried various exec queries including exec() (with var before function call and as a parameter), passthru, backtick operators and none of them allow me to use the array after the commandline tool has been run. I also dont know how many levels the array may have as im referencing other functions that change them based on the query given to the commandline tool so I cant even put it into a string before returning it as i dont know how many levels are involved and are returned from the function call inside the commandline app. Does anyone have any suggestions as to how I could achieve this or any better ways of doing it? Quick summary: Im accessing a web interface that calls a php file to parse some info. That php file may get an array back that I need to use in the web interface - but I cant pass it back to the web interface from the commandline tool.

[PHP] Using Googles SSO for GApps
Hi, I was wondering if anyone has set up SSO using googles api for apps. http://code.google.com/apis/apps/sso/saml_reference_implementation.html is their implementation guide but I was wondering if anyone has done it, and if I could have a peak at the code you used, mainly for the encrypting of the information being sent, also for the generation of the xml. I have done some googling and can find a few java implementaions, but no php ones - maybe I cant search so if there are some examples around please excuse my ignorance.

[PHP] path_info in fastcgi setting
Greetings all. Making the transition to PHP 5.2.5 operating as FastCGI through Nginx. Seem to be having a bit o' weirdness with path_info. Under Apache and the PHP module: a) test.php path_info is blank b) test.php/ppp path_info=/ppp Under PHP FastCGI: c) test.php path_info is test.php d) test.php/ppp path_info=/ppp Not sure why it's not blank in 'c' and instead equals the filename.

Hi,
We recently upgraded our primary webserver to php 5 from php4 and we are now
getting the following errors on the site:
*Catchable fatal error*: Object of class stdClass could not be converted to
string in /home/www/somesite/somfile.php on line *199
*Around that area in the code is some code something like:

{

}
Any ideas what it means or how I can fix it ?

[PHP] Database Class Help
Hi,
We have a database class that we want to use to connect to multiple
databases at the same time using different variables.
Here is part of the db class:
class db {
var $dbh = "";
var $q = "";
function db($db_host, $db_user, $db_pass, $db_name) {
$this->dbh = @mysql_pconnect($db_host, $db_user, $db_pass);
$this->select_db($db_name);
}
function select_db($db) {
if ([EMAIL PROTECTED]($db, $this->dbh)) {
die("Cannot select database because:\n" .
mysql_error() . "");
}
}
function num_rows($_q) {
if (!$this->q = mysql_query($_q, $this->dbh)) {
die("Invalid query \"" . $_q . "\"\n" .
mysql_error() . "");
} else {
return mysql_num_rows($this->q);
}
@mysql_free_result($this->q);
}
}
In my php file I say something like
num_rows('select * from table1');
Echo $db_2->num_rows('select * from table2');
?>
Now that happens is when I try and do the query for db1, I get told that
db2.table1 doesn't exist. I can swop anything around and it doesn't seem to
work for one of the classes.
Does anyone have any idea as to why this is happening?
Thanks a lot,
Ian

RE: [PHP] Help with Class
Hi Ryan,
I am including a different class.inc.php file each time the foreach loops.
Each one sits in a different dir. Yes, I do get that error.
My understanding of OOP is that I could null the $sdk variable and re-init
it when the loop starts again..

What is the above line doing? It looks like you are trying to redeclare
the ipbsdk class each time around the loop which is illegal in php. You
can't do :
class ipbsdk {
...
}
and then (in the same request)
class ipbsdk {
...
}
because the names will clash. This should cause a "Fatal error: Cannot
redeclare class ipbsdk ..." message though. Are you seeing any errors?

Sorry for not explaining ... [code]$SDK =& new ipbsdk;[/code] initializes
the $SDK variable as a reference of the class ipbsdk. The '&' operator is
called the reference operator. So by leaving it out you copy (the default
initialization) the resulting class object.
Maybe that does the trick.

Hmm, that is strange because OO tells us that by nulling an object you
destroy it. I don't see what the other person could have done to avoid the
destruction of his class ... (that would be above my head)
One more thing I would try (which you have not done yet) is to initialize
the class as a copy and not a reference. That should not impair your code
much because you are creating a new one ever time anyway.
> think it cant be done
That would somehow go against my understanding of OO programming ;-) ...
Good luck.

Hi,
I put the db object in there temporarily because the SDK class resets it and
I haven't gotten round to changing it yet.
I tried initing $SDK to null at the start but that hasn't worked either.
The class that I initing isn't mine, it was written by someone else and they
don't allow for multiple directories. The first run in the foreach loop runs
perfectly, I get all the info back I need, so its just when the loop runs
again.
Here is my current code with all options I have tried:
foreach ( $forums as $num=>$val )
{
$SDK=null;
$sdk = null;
$db = new db ( 'localhost' , 'user' , 'pass' , 'db' );
$sql = 'SELECT * FROM vaults WHERE id = "'.$val.'"';
$result = $db->get($sql);
$fetchd = mysql_fetch_array ( $result );
$forumid = $fetchd['forumid'];
$posterid = $fetchd['posterid'];
$title = $_POST['title'];
$desc = $_POST['desc'];
$post = $_POST['post'];
require_once ( $fetchd['path'].'sdk/ipbsdk_class.inc.php' );
$SDK =& new ipbsdk;
$info = $SDK -> get_info ( $posterid );
$postername = $info['name'];
echo "Forum ID:".$forumid;
echo "Title:".$title;
echo "Desc:".$desc;
echo "Post:".$post;
echo "PosterID:".$posterid;
echo "PosterName:".$postername;
echo "";
// if ($SDK -> new_topic($forumid, $title, $desc, $post, $posterid,
$postername)) {
// echo 'Topic Created!';
// } else {
// echo $SDK->sdk_error();
// }
unset ( $sdk );
$SDK = null;
unset ( $SDK );
$sdk = null;
unset ( $GLOBALS['SDK']);
unset ( $GLOBALS['sdk'] ) ;
$GLOBALS['SDK'] = null;
$GLOBALS['sdk'] = null;
$_SESSION['sdk'] = null;
$_SESSION['SDK'] = null;
unset ( $_SESSION['SDK'] );
unset ( $_SESSION['sdk'] );
register_shutdown_function($SDK);
register_shutdown_function($sdk);
}
So as you can see, I have tried a lot of things and im starting to think it
cant be done, in which case ill just have to take the other persons class
and either modify it (which is against his terms) or take what he does and
do it manually myself.
Thanks for the help.

First up, I am not sure if you need to create a new db object every single
loop, as far as I can see you can easily leave that outside the loop (unless
you connect to a different db on each loop).
Maybe you could initialize the $SDK variable on top of your loop with null
($SDK=null;) that way ever loop will serve you up with a 'nulled' $SDK
variable.
Does your current code not initialize the correct classes?

[PHP] PHP Security
I have been studying PHP all summer because I wanted to put some PHP code on my schools web site. I got to school and went to the web design teacher. I asked him if they had installed PHP on their server.

wow you php bunch are a vocal lot.. ;-) no other mailing list had a peep. ok. let me try to answer the questions.. and apologies if I offend, it isn't the intention. the answers your have given me are great (I wish u stuck them in the survey form, but no matter) you've just given me 2 different reasons on 'why apache' then the previous poster. you said: stability & 'leanness' he said: performance & price. Others have also mentioned other reasons like ease of configuration, modularity and so on. The point is each of you are unique individuals with different reasons and experiences. If no one asks, we wouldn't know, we could just make a gut choice .. which would most likely be wrong. now.. why demographics.. have a look at http://www.biznix.org/surveys/ for a different picture of apache's server usage stats. people in america in fortune 500 companies use IIS more than people in 'the world' in global 500 companies... so where you live does make a difference. who knew? as for how we could use this information. I put the demographic in there to see what kind of person you are, and to see if there was any correlation between where you live and how you answered. ie.. people in Europe think documentation is a big issue, while the people in the USA are more concerned about performance. (this might be because the French documentation is really bad.. which would be interesting in itself no?). BTW.. your IP# would have given me a whole lot of this information as well. I was just being polite (and lazy.. I didn't want to implement the same thing the php website does for it's download mirroring) and to address your other concern.. why 'PHP'.. easy.. you guys use apache and IIS. PHP is so great it can run on both.. you guys have a *choice*.. If we didn't listen to what you guys say.. you wouldn't choose us next time. mod_perl or .NET users don't have that choice. if you do know a IIS mailing list, please feel free to mail me.. I really couldn't find any. Kind regards Ian Holsman.

[PHP] Apache Webserver User Survey
Hi. I am conducting a survey about what users want out of a webserver and how the Apache webserver ranks as far as fulfilling those needs. In order to get a better understanding of it, I thought I would ask you guys what was important to you. The survey should take about 10-15 minutes to complete. http://survey.zilbo.com/php.survey I wish I could say there was a prize being given away if you fill it out, but there isn't.. This is 'opensource' research.. I don't have a marketing budget ;-) Thanks Ian Holsman [EMAIL PROTECTED] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Bug in look-behind assertions in PCRE patterns ?
Dear All
Is this a bug ?
I'm using look-behind assertions within preg_match()
to ignore certain combinations of patterns. E.g. from
ref. manual is: (?
Here's my test script:
$line = '$res = foobar("ddd", "dfdf");';
if (preg_match("/(?
$line = '$res = $bar("ddd", "dfdf");';
if (preg_match("/(?
In the first preg_match() is correctly ignores the foobar
function name. However the second preg_match() does NOT
ignore the $bar as I expected.
I converted this to Perl and it correctly ignores both!
Is this a bug, or am I missing something ?
using PHP-4.3.10 + apache 1.3.33 + fc 1
Many thanks
Ian

Re: [PHP] unexplainable - page generation time class
I think the problem is how, when and where you're calling things.
Basically, your code is fine. I modified it slightly and get the correct
output. This could still be cleaned up and optimised significantly;
however, I think you can take it from here:
Your Class:
cls_start_time = $microstart[0] + $microstart[1];
return $this->cls_start_time;
}
//
// FIGURE OUT THE TIME AT THE END OF THE PAGE
//
function stop() {
$microstop = explode(' ',microtime());
$this->cls_stop_time = $microstop[0] + $microstop[1];
return $this->cls_stop_time;
}
//
// CALCULATE THE DIFFERENCE BETWEEN THE BEGINNNG AND THE END AND
COLOR CODE THE RESULT
//
function gen($start, $stop) {
$this->cls_gen_time = $stop - $start;
return $this->cls_gen_time;
}
}
?>
index php that calls it:
start();
sleep(2);
$stop=$page_gen->stop();
echo("start/stop: $start $stop");
$gentime=$page_gen->gen($start, $stop);
echo "generation time: ". $gentime;
?>
Output:
start/stop: 1110096261.12 1110096263.13
generation time: 2.00168681145
All the best,
Ian

cannot find the mysql version ?
Any advice ?

[PHP] Problems displaying images with PHP-GD
Hello
I am trying to use GD to create and manipulate images but the
statement:
header ("Content-type: image/jpg");
generates the error message:
The image "http://localhost/gdtst2.php"; cannot be displayed, because
it contains errors.
There is no error message in the ../httpd/error_log file.
I am using PHP 5.0.3 with GD 2.0.28. The report from phpinfo()
indicates gd present and enabled. Other nongraphics content-types do not
gererate errors.
Code used was "First Program" from tutorial at
http://www.phpfreaks.com/tutorials/105/1.php. Similar code from php
manual generates the same error.
I suspect the solution is simple but I'm just not seeing it!

Re: [PHP] Writing new code vs. re-writing someone else's code
Good question. Personally, I think I tend to write more new code than reworking old code. However, I have taken on numerous projects where I've been required to port ASP to PHP and MSSQL dbs to Postgre or MySQL... but these projects also require a fair bit of new code. There are *so* many legacy COBOL applications though that, yeah, I think a COBOL programmer will very rarely get to write anything new. The people who I know who work with COBOL generally either patch problems or, if there's new functionality required, will code in Java or C.

[PHP] mixed strings
Hi All, I'm wondering if anyone knows if there's a way of sending strings of mixed type to a UDP socket. I'm storing the data I need to send in an array. Parsing the array with a foreach, I'm sending out the various pieces to the socket with fwrite. Unfortunately, it seems that UDP terminates each message and the client is expecting everything in one chunk with each byte of a specific type (ie. ASCII, INTEGER, BCD) Is there any way I can write a string of mixed types to an open UDP socket as a single message?

Ciao Tomas, I'm not sure if I followed your question completely but do you mean to test a variable or an array element and unset it if it matches a certain type? If so, then maybe: http://it.php.net/is_int is_bool(), is_float(), is_numeric(), is_string(), is_array(), and is_object() will be of help?

Try opening the file "rw". At the moment, you're opening it read only.

Thanks Richard.
I thought of that too and have since expanded my debugging. The types
are correct when passed to fwrite. They come out the other end as
strings:
16:39:54 SENT 'K' of type string
16:39:54 SENT '0' of type integer
16:39:54 SENT '0' of type integer
16:39:54 SENT '65' of type integer
16:39:54 SENT '31' of type integer
15:46:10 192.168.0.101:32778 --> 192.168.0.84:32896 | UDP |
: 4b K
15:46:10 192.168.0.101:32778 --> 192.168.0.84:32896 | UDP |
: 30 0
15:46:10 192.168.0.101:32778 --> 192.168.0.84:32896 | UDP |
: 30 0
15:46:10 192.168.0.101:32778 --> 192.168.0.84:32896 | UDP |
: 3635 65
15:46:10 192.168.0.101:32778 --> 192.168.0.84:32896 | UDP |
: 3331 31
As you can see, the last two elements "65" and "31" have arrived as
strings of two bytes rather than integers of one.

Re: [PHP] "Byte Array"
Just a follow-up to myself... I decided to try packet sniffing to see
what was going on and ettercap confirms that I'm sending out strings
rather than data of the type stored in my array:
16:12:26 192.168.0.101:32779 --> 192.168.0.88:32896 | UDP |
: 3331 31
That "31" should be an integer of only one byte, not two.
The function that's doing the sending looks like this:
function send_back($sock, $msg, $ip, $port) {
$fp = fsockopen("udp://$ip", $port, $errno, $errstr);
foreach ($msg as $msg_to_send) {
fwrite($fp, $msg_to_send);
echo date("H:i:s")." SENT '$msg_to_send'\n"; //seen server
side
}
fclose($fp);
}
Can anyone see where I might be going wrong? Why am I not sending the
integers as integers and the binary bits as binary bits?

I have removed some details such as passwords and swapped that with question marks. Many thanks, Ian Gray Here is the code? http://www.w3.org/1999/xhtml";> Customer Login
Re: [PHP] How do I su to another account??
Do you really need to switch users or do you need to run something as another user? Try looking into setting up and using sudo.

Re: [PHP] passing resources from one script to another
Thanks Greg. That is what I'm doing. The problem remains passing a resource to the script executed by exec.

Re: [PHP] passing resources from one script to another
I should have specified that this is a shell script, not a web application. I have a listening process running. The listening process calls another script once a connection is established. This is done via exec. It works; however, I can't pass a resource directly to the other script. Therefore, I've passed the resource to "serialize()" and pass the resulting string to the other script as an argument. My idea was to "unserialize" the string in that script. I expected to get a resource back; unfortunately, I get an integer. My question is: is there any way to pass a Resource between scripts?

[PHP] passing resources from one script to another
Hi All, I'm developing a small server application that accepts connections on a socket and then launches an interactive session with the client. The server needs to be able to accept N connections. This part is working famously thanks to code I've borrowed and modified from: http://www.zend.com/lists/php-dev/200205/msg00286.html The problem is the dialogue with the client. If I enter into a while loop then the whole script remains occupied and cannot accept new connections. If I try to open a new background process with exec, then I need to pass a resource from the listening script to the dialogue script. However, it seems that I cannot pass a resource between scripts. If I serialize the resource, passing it as a string to the dialogue shell script, then unserialize it in the dialogue script, it's no longer a resource but an integer... Any ideas on how to get around this problem? Can it be done with PHP? Ian -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Most efficient way of fetching 1,000 records from MySQL ?
I think you'll find that your first approach is not only more correct,
it's the only manageable one.

Re: [PHP] PHP App User Permissions Tecnique
Definitely store them in a session. A db lookup will mean a much heavier and process intensive procedure.
