Using while and foreach

[Marco]

Hi there ;)

Im building a MySQL table for a menssaging system, its a table that has 3
fields de UserID, MTime and Mess.
My problem is that i cant find a way that using only a mysql query i get the
time and the message, and that for each row.

Basicly the code would look like this, to give an idea...

<?php
$News=mysql_que ry("SELECT MTime,Mess FROM Star_Mess WHERE UserID = '$UID'
ORDER BY MTime DESC");
while ($line = mysql_fetch_arr ay($News, MYSQL_ASSOC)) {
foreach ($line AS $Date) {
print "\t\t<p><b>$Dat e</b></p><p>$Mess</p>\n";
}
}
?>

Any ideas how to do it ?

The main look of the thing is to have the Time in bold followed by the
message, and that for each row.

Thx

Marco

(slightly edited)

<?php
$News=mysql_que ry("SELECT MTime,Mess FROM Star_Mess WHERE UserID = '$UID'
ORDER BY MTime DESC");
while ($line = mysql_fetch_arr ay($News, MYSQL_ASSOC)) {
# foreach ($line AS $Date) {
print "\t\t<p><b>{$li ne['MTime']}</b></p><p>{$line['Mess']}</p>\n";
# }
}
?>

mysql_fetch_arr ay() [as the name suggests] returns an array; so your
$line variable will be something like

$line['MTime'] = '2004-02-03';
$line['Mess'] = 'Message text';

When you do the foreach() to this array, it will loop twice. The first
time $Date will have '2004-02-03' and the second time it will have
'Message text'. Doing it with the foreach gives you no control over each
of the isolated elements; use them directly from the $line array.


Hope this helps.

I think this should work:

while ($line = mysql_fetch_arr ay($News, MYSQL_ASSOC)) {
print "\t\t<p><b>".$l ine['MTime']."</b></p><p>".$line['Mess']."</p>\n";
}

You might want to use htmlentities(), at least on the Mess.

Indeed i noticed it did 2 times the loop ,when i tryed to use it the first
time.

Thanks for your insights.

It works great even with out using the htmlentities(), im going to see what
htmlentities do in the manual, just in case i need it or if its better to
use it.

Thanks
