what is the third array?
can it be simplyfied? it's really confused me.

ASKER
and what this means: projGroup[$i][1] = explode("XX", $rw['LOCATIONS']);
The third array is the actual value of the field so it goes like this:
$projGroup[recordnum][fiel
It could be simplified, assumming you only have one location, one time and one limit per each record in the database.
I would do something like this:
$projGroup[recordnum][fiel
It could be simplified, assumming you only have one location, one time and one limit per each record in the database.
I would do something like this:
while ($rw = mssql_fetch_assoc($rslt))
{
$projGroup[] = array("PROJTIME" => $rw['PROJTime'],
"LOCATIONS" => $rw['LOCATIONS'],
"LIMIT" => $rw['LIMIT']);
}
#get values like this:
foreach($projGroup as $key => $val) {
echo $key . ": " . $val . '<br />';
}
#or to get a specific field of a record:
$recnum = 1;
echo $projGroup[$recnum]["LOCATIONS"];SOLUTION
