I think I already know the answer to this question, but I just
want to make certain.
Is there a way that a class can know the name of the variable
used to instantiate it?
So if you do:
$joeBob = new myClass();
"myClass" can somehow know that "joeBob" is the name of
it's instance?
I'm
Good idea, I agree, this would be nice. It would allow
posters to better categorize their question, and would
give responders a good place to hangout depending on
their skill set.
This has been suggested before. What you will invariably
find is that all users (beginner and advanced) will
Besides, sometimes I think that PHP is so easy to learn
that we should be considered unskilled labor ;-)
The skill is in the shaping. Any joe off the street can make an
ugly sculpture. It takes talent and skill to make art...

What is the way to exit a function? For example:
function FooBar() {
if ($foo = $bar)
Exit_this_Function;
## otherwise execute the rest of this function
}
function FooBar() {
if ($foo = $bar)
return 0;
}
## otherwise execute the rest of this function
}

Academic curiosity -
You can do the following:
echo "3 - 2 = " . ( bcsub( 3, 2 ));
and PHP evaluates the expression in parenthesis (in this
case a function) before it evaluates the echo statement
and what gets printed out is:
3 - 2 = 1
Now, say I have a function where one of the arguments
What about using normal pass-by-value and returning the result?
function MyFunc ($SomeVal) {
$SomeVal += 42;
return $SomeVal;
}
echo MyFunc ($StrangeVal);
I'm already using the return value for something else.
Anyway - functions that get their parameters by reference and
modify
Anybody knows if this sourcecode is correct to calculate the
numbers of days in certain date ?
Why are you going through all that effort?
$janOne = mktime( 0, 0, 0, 1, 1, date( "Y" ));
$myDate = mktime( 0, 0, 0, $m, $d, $y );
$daysInYear = ( $myDate - $janOne ) / 86400;
That should do it

We need something to where we can poll a service and
pull the exchange rates for various currencies against
the dollar to our database for later use. Is there a PHP
library/class that does something like this already? Just
so I'm not reinventing the wheel? :p

When you are using mysql_insert_id, you don't want to pass it
the result of your previous SQL statement as in:
$result = mysql"mydb", "My SQL statement", $my_connect) ;
$last_id = mysql_insert_id($result)
This is what it sounds like it's looking for in the documentation. It
could be just
Instead of checking if(!$id), perhaps you would be better off to check the
result of your query (which in this example was successful, since you got
a return from mysql() ).

I've been charged with trying to find out how something
like this can be done if it is at all in fact possible. The info
I'm hoping to get is what would be involved and where I
can find information on it. I'm not asking for code or
examples unless you really want to provide them. :P
Anyways,
Have the user log in to/authenticate against the first server.
That server generates a key, based on combining the username
and a private key known to the authenticating server and your
servers.
Pass that back to your servers in a URL - cookie wouldn't
work, but the key in the URL should
Does anyone know a function to give me the mySql field types?
I saw the function mysql_field_type, but that returns php types not
mysql. What I wanna do is if the type of the field is "Text" then I
wanna make a "textarea" to edit and add stuff. Thanks.
If you have phpMySql, take a look
If you have phpMySql, take a look at the file:
/mysqladmin/tbl_properties.php
That code is doing something to return the type of the field. It's a
little hard to follow so I don't know exactly how he's doing it and
unfortunately, didn't have the time to decipher. :p However, I'm
sure if
What is the syntax for dividing 7 by 2 and getting 3; not 3.5?
you can use:

Yeah, I didn't think so. But I knew that '' behaves differently
than "". I just wasn't sure of the exact details of the differences.

Try looking at register_shutdown_function at
http://www.php.net/manual/en/function.register-shutdown-function.php
From the documentation:
"int register_shutdown_function (string func)
Registers the function named by func to be executed when script processing
is complete."
What qualifies as
Ive gotto format a date such as 30/12/1956 to format 30-Dec-1956,
I can not use mktime cause that only provides the timestamp from 1970.
Is there any other method of getting this right.
mktime() can be used for this. 0 is from 1970. Negative values are used
for dates prior.

"allow per session cookies(not stored)" will enable cookies,
IE just does some garbage collection when its closed thats all.
so php realizes that IE is accepting cookies in this case and
uses cookies vs trans-sid.
Ok. Makes sense.
However, when this option is enabled, I see PHPSESSID
make sure of course too that session_start() is called from
in your code too. else your not using sessions :)
These are the 3 files I'm using; they all reside in the same dir:
"index.php"
script language="php"
session_start();
header( "location: page1.php?" . SID );
exit();
