Re: [PHP-DB] Expiry Date ($date function)
The strtotime function should work the best.
$add_twentyone = strtotime(+21 days);
I dont know if that will work or not. I just found that method in the
php doc and it looked interesting. Hopefully it will work for you.

I figured out that the syntax below creates the date in the way it may be
stored in a mySQL table:
$todays_date=DATE('Y-m-d');
Is there any way to add 21 days to this as an expiry date? For example if
the date was March 20th 2005 21 days would be in April --- is there any way
of dealing with this?

Re: [PHP-DB] mysql_num_rows
That means that you dont have any rows to work with. It could mean that you are not connected to the database, or the query you performed did not return any rows.

Re: [PHP-DB] Queries close session
Because the session you are using probably uses a cookie to remember
the session, it is required that you call session_start before you
output anything to the screen(aka: send any headers). So if you place
the session start at the very top of your page before you include any
files or output anything, the session should work. Beware of any
whitespace before the ?php tags because that will also send headers.

I am using the following script to maintain a login session on some

session_start();

or that your session has expired.

}
?
The sessions are stable and work fine EXCEPT when I run another PHP
script on the web page such as:
?php
// Make a MySQL Connection
require db_connect.inc;
// Retrieve all the data from the example table
$result = mysql_query(SELECT * FROM members WHERE Status='Inactive')
or die(mysql_error());
echo table border='1' cellpadding='0' cellspacing='1'
align='center';
echo tr thCertificate #/ththDan rank/ththFirst Name/th
thLast Name/th /tr;
// keeps getting the next row until there are no more to get
while($row = mysql_fetch_array( $result )) {
// Print out the contents of each row into a table
echo trtd;
echo $row['Cert_number'];
echo /tdtd;
echo $row['Dan_rank'];
echo /tdtd;
echo $row['First'];
echo /tdtd;
echo $row['Last'];
echo /td/tr;
}
echo /table;
?
I'm assuming that I am either not maintaining the session properly or
not linking the scripts to the session.
Any pointers on how to accomplish what I'm trying to do?
Thanks,
- Ken

Re: [PHP-DB] File retrieval
The methods suggested above would all work but if you would like to do in one step you could use file_get_contents(). This method does not require you to open/close the file and will automatically read the entire file into your array. ?php $contents = file_get_contents(data.txt); ?
