what is meaning of below code
$depart_time=$res[0][‘BRD_TM’];
set the value of the variable depart_time to the value of the BRD_TM column in the first row of the multi-level array in the res variable
$res looks something like this
[php] $res = array(
0 => array(
‘ID’ => 1,
‘BRD_TM’ => 1016
),
1 => array(
‘ID’ => 2,
‘BRD_TM’ => 1551
)
);[/php]
in this case $res[0][‘BRD_TM’] / $depart_time would equal 1016
