Does anybody know how to remove an item from an array?
Let's say
$array('banna', 'apple','cherry')
foreach ($array as $value) {
if ($value=='chery') DELETE $value FROM $array
...
Thanks
Hiya,
Just wondering what is the rough idea of speed of a server like this is
holding a database with millions of records. I know its difficult, depends
on the data stored etc.
Its basically storing an index int and about 5 or so char field (50
long). In total I want to store 500 million
Hi
The following will print the variables ($tim1 and $tim2) correctly but the
IF statement using the same vars will not work, it will only work as below
which seems to work by comparing the text values of the 2 variables $tim1
$tim2.
while($myrow = mysql_fetch_array($result))
{
$tim1=timea;
Hi

Hi
I've written a guestbook in php
user writes a message in a texarea and
SELECT * FROM user_tables;
will give you the list of tables and properties.
I think the table name's columns is called: 'table_name' so this should
be:
SELECT table_name FROM user_tables;

Hello All!
i am new to the list to PHP..
So i have a recordset that displays my contacts in a table.
the headers of the columns look like this.
tda href=default2.php?orderBy=priLastNameLast Name/a/td
so when a user clicks on it
It will Re-Sort the rs by priLastName Asc.
what i want to do is
Let's see:
?
$dir = ((isset ($_GET['dir'])) ? (int) $_GET['dir'] : 1);
if (!$dir)
$direction = 'desc';
$dir = ($dir ? 0 : 1);
?
tda href=default2.php?orderBy=?=$colname?dir=?= $dir?Last
Name/a/td
This is the general idea. $dir will toggle between 1 and 0. There are
more compact ways

you would...)

It would seem that your IF statement, as it is written below, evaluates to
true every time because I'm guessing that the hexadecimal value of the
string timeb is larger than the hexadecimal value of timea. Like I said,
just a guess.
I'm also guessing that you actually want to compare two values
Index is always re-indexing itself on INSERT/UPDATE. Roughly, I don't
think there is any difference in when you create an index before or
after table is populated.

well i tried that..

but it is not taking that var to switch ACS or DESC...

I think you might be missing a = sign in your if statement.

The biggest table was a log table of about 2.5+ million rows. Ran reports

I am trying to do a search and replace into a text file that will then

So I have been able to do this with simple ..['name'] variable replace.
But how do I get it to save the results into a text file.

The problem is, I need to make a page that shows all of the polls, and
one query per poll would kill the server.

Leif,
off the wall...what if you have a table for question, identified with an
unique ID, and another where you store the results? BTW: how are the
questions? Yes/No, or multiple choices, or combination of these two
styles?

Hi,
I've dealt with databases with about 100 million records
(100Gb of data/indexes), using Oracle, and i'm glad we did.
If you database is 5 times larger than our largest one, you definitely
you need Oracle or something high end.

Red Hat Advanced Server is better - it has Oracle patches for better
asynch i/o performance.
If for Oracle, I'd then recommend SuSe.

But, remember - you don't rebuild completely an index - you rather add

So, there are three scenarios:
1. Q: You create the table to then send into it lots of data row per row
A: create the table first, then build an idex on it once.
2. Q: You have to constantly be adding the data
