PHP Language - While Loop Question...

While Loop Question...

2006-01-23, 3:55 am

Hi All

I'm trying to create a loop in PHP which will do the following for me :-

1. Get a count of rows from a table where the current time is greater than
the expired_time.
2. Based on that, we need to get the customercode from that table, to be
able to get an e-mail address from another table where the customercode
matches.
3. Send a notification to the email address to inform the client that the
time has expired.

For now, I have left out the e-mail address part as well as the actual
e-mail sending part. I guess that will happen in the same loop. For now, I
am just trying to get a list of the customercodes. Don't know if i'm on the
right track here...

<?
include "../includes/mysqlcon.php";
echo "hello...";

$current_time = date("Y-m-d H:i:s");

$count = mysql_query("SELECT count(nid) FROM nack_ack where '$current_time'
> date_expired");
$numrows = mysql_num_rows($count);

$i = 1;

while ($i <= $numrows) {

$querycustomercode = mysql_fetch_row(mysql_query("SELECT * from nack_ack
WHERE nid = '$i'"));
$customercode = $querycustomercode[1];

echo $customercode;

}
?>

You are not incrementing $i in the loop anywhere, so it will run forever.

<?
include "../includes/mysqlcon.php";
echo "hello...";

$current_time = date("Y-m-d H:i:s");

$count = mysql_query("SELECT count(nid) FROM nack_ack where '$current_time' >
date_expired");
$numrows = mysql_num_rows($count);

$querycustomercode = mysql_query("SELECT * from nack_ack WHERE nid <
'$numrows' ORDER BY nid ASC");

while($row=mysql_fetch_row($querycustome
rcode)) {
$customercode = $row[1];
echo $customercode;
}
?>
