Answer 1

I would recommend when defining your first array to set the keys to the reg_id.
For example if you were creating this array from query results:
$results = array();
while($row = mysql_fetch_assoc($blah)){
$id = $row['reg_id'];
$results[$id] = $row;
}
Then when you loop through your second array you can easily update the first.
foreach($secondArray as $key => $row){
$id = $row['reg_id'];
$val = $row['TotalInv'];
$first[$id]['TotalInv'] = $val;
}
Arrays are a beautiful thing! Hope that helps!

Do you mean:
foreach($yourArr["RX Housing"] as $key => $val) {
if($val["reg_id"] == 10) {
$yourArr["RX Housing"][$key]["TotalInv"] = 2;
}
else {
$yourArr["RX Housing"][$key]["TotalInv"] = 20;
}
}
Hope it helps

try this
$a = Array
(
'RX Housing' => Array
(
Array
(
'reg_id' => 63,
'vRegionName' => 'Boston',
'Forwarded' => 1,
'Accepted' => 0,
'Rejected' => 0,
'Dupe' => 0,
'PotentialLease' => 0,
'Lcpc' => 0,
'CloseLead' => 0,
'TotalInvamt' => 0.00
),
Array
(
'reg_id' => 41,
'vRegionName' => 'Chicago',
'Forwarded' => 1,
'Accepted' => 0,
'Rejected' => 0,
'Dupe' => 0,
'PotentialLease' => 0,
'Lcpc' => 0,
'CloseLead' => 1,
'TotalInvamt' => 954.00
)
)
);
$b = Array
(
'RX Housing' => Array
(
Array
(
'reg_id' => 63,
'TotalInv' => 2
),
Array
(
'reg_id' => 41,
'TotalInv' => 8
)
)
);
foreach ($a['RX Housing'] as $value) {
foreach ($b['RX Housing'] as $value1) {
foreach ($value as $key => $result) {
if (array_key_exists($key, $value1)) {
if ($result == $value1[$key]) {
$value = array_merge($value, $value1);
$c['RX Housing'][] = $value;
}
}
}
}
}
var_dump($c);
out put is
