Thanks, Ryan One of the things to think about with this is, although you may have a few hundred users signed up how many are online at once.

Another idea that goes with what Chris had said is to use a join on your online table.

[PHP] Passing by reference, assigning by reference?
Hi sports fans!
I have a quick references related question.
Ok, I'm passing a Page object by reference to another object:
myClass-myFunction($objPage);
What I want to do is store that Page object as part of the myClass
object (see definition code below).
My question is this: When assigning the Page object to be a variable of
the myClass object do I store a reference to it or a copy of the reference?
class myClass()
{
var $objPage;
function myFunction($objPage) {
// this way (a reference to the reference?):
$this-objPage = $objPage;
// or this way (a copy of the reference?):
$this-objPage = $objPage;
// code, code, code...
}
}
Is there much difference? Does it really matter? I'm unsure if this is
efficient or not.
Can someone please shed some light on this.
Thanks!

[PHP] Ticket Number
Hello, We're in the midst of creating a high volume transaction platform with PHP and MySQL. Each transaction ties to a transaction ID that is in turn an auto_increment, unsigned BIGINT(12). The problem now is I do not want users to see this running transaction ID when using the system (such that we can roll out surprises for the customer of, say, the 10th million transaction). We plan to convert the id to something like [A-Z0-9]-[checksums], (e.g. 1X2Z0HTDEKS93-C8P), for simple input-error detection, and we can use it to lookup the relevant id from the database. Which algorithm(s) in your opinion is the best for the encrypted transaction ID and checksum such that: - Transaction ID should always be unique - Running sequence is not predictable (when you have 2 transactions, you don't know how many transactions are between them) - Contains only alphanumeric and case insensitive letters of not more than 15 characters, excluding checksum We've thought of using the first 15 characters of a MD5 hash, so we can kind of SELECT substring(MD5(t_id)... during lookup, and CRC16 for the checksum. Someone also suggests scrapping the auto_increment field from db and generate our own using the below method while (t_id exists in db) randomize but i see the 2nd method being quite taxing to the server as you have to query at least one time per transaction. I appreciate all inputs. Thanks! Sincerely, Kenny -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

John
I think you have a slightly more complex situation than just replacing text
between what I assume is a LIKE or multiple WHERE situation and a fulltext
search. Perhaps if you can give an idea of the type of string you are
likely to get in $searchenquiry, and to what you wish to convert it, we
might be better placed to give advice.
I can envisage that you might get 'bananas NOT pears AND apples' in the
variable; I guess you would currently manipulate that to a query such as
WHERE x = 'bananas' AND x 'pears' AND x = 'apples'
(OK that's not a good example) but if you were to feed that to a fulltext
search you might want
WHERE MATCH (x) AGAINST ('+bananas -pears -apples' IN BOOLEAN MODE)
or maybe something else depending on the version of Mysql and exactly what
you are trying to do with your fulltext search.

I think you have a slightly more complex situation than just replacing
text
between what I assume is a LIKE or multiple WHERE situation and a fulltext
search. Perhaps if you can give an idea of the type of string you are
likely to get in $searchenquiry, and to what you wish to convert it, we
might be better placed to give advice.
I can envisage that you might get 'bananas NOT pears AND apples' in the
variable; I guess you would currently manipulate that to a query such as
WHERE x = 'bananas' AND x 'pears' AND x = 'apples'
(OK that's not a good example) but if you were to feed that to a fulltext
search you might want
WHERE MATCH (x) AGAINST ('+bananas -pears -apples' IN BOOLEAN MODE)
or maybe something else depending on the version of Mysql and exactly what
you are trying to do with your fulltext search.

[PHP] Re: AND OR NOT
David,
I'm under pressure to permit AND, OR NOT. My research group insists
that MySQL 4 syntax is not good enough.
An idea of what one might enter is here (on the bottom):
http://compcanlit.usherbrooke.ca/advanced.html
I was hoping to get away with replacing AND with +, NOT with
- and OR with .
I use this as SQL:
SELECT *,MATCH (YR,AU,ST,SD,SC,BT,BD,BC,AT,AD,AC,JR,KW,AUS,TUS,GEO,AN,SA,RB)
AGAINST ('$mydata-searchenquiry' IN BOOLEAN MODE)
AS relevancy FROM ccl_main
WHERE MATCH (YR,AU,ST,SD,SC,BT,BD,BC,AT,AD,AC,JR,KW,AUS,TUS,GEO,AN,SA,RB)
AGAINST ('$mydata-searchenquiry' IN BOOLEAN MODE)
ORDER BY relevancy DESC;--

Please don't top-post [1]. Nice cryptic column names, by the way :)
Your research group obviously haven't researched very carefully, as
+term is exactly equal to AND term, -term to NOT term and
simply term to OR term. So there's no point in complicating the syntax.
Not only that, but MySQL's boolean mode fulltext search offers many more
great possibilities like truncation (app* will match apple,
application...) and in-query relevance altering. Take a look at the
BOOLEAN MODE section of the MySQL manual [2]; maybe print it and give it
to your research group :)
