I don't see your code so I am trying to make own code.
$arr = array(
array(
'fname' => 'jone',
'lname' => 'jani',
'gender' => 'm',
'rname' => 'N'
),
array(
'fname' => 'jani',
'lname' => 'jone',
'gender' => 'm',
'rname' => 'N'
),
array(
'fname' => 'sara',
'lname' => 'bulbula',
'gender' => 'w',
'rname' => 'D'
),
array(
'fname' => 'hani',
'lname' => 'hanu',
'gender' => 'w',
'rname' => 'P'
),
array(
'fname' => 'ttttttt',
'lname' => 'sssssss',
'gender' => 'm',
'rname' => 'C'
),
);
$matrix = array();
foreach (array('N', 'D', 'P', 'C', 'total') as $name) {
foreach (array('m', 'w') as $gender) {
$matrix[$name][$gender] = 0;
}
}
foreach ($arr as $el) {
$matrix[$el['rname']][$el['gender']] += 1;
$matrix['total'][$el['gender']] += 1;
}
echo '<pre>';
print_r($matrix);
echo '</pre>';
// OR dynamicaly keys
$matrix = array();
foreach ($arr as $el) {
if (!isset($matrix[$el['rname']][$el['gender']]))
$matrix[$el['rname']][$el['gender']] = 0;
if (!isset($matrix['total'][$el['gender']]))
$matrix['total'][$el['gender']] = 0;
$matrix[$el['rname']][$el['gender']] += 1;
$matrix['total'][$el['gender']] += 1;
}
echo '<pre>';
print_r($matrix);
echo '</pre>';

I have a similar function which I have used to do something similar to your request.. So this is just a copy and paste, because you have shown a lack of code.. This returns an array as your expecting.. Just iterating over this returned array, is something you will need to research into yourself
function Array_Counter($Array){
$Return_Arr = array(
"M" => array(),
"F" => array()
);
foreach ($Array AS $Arr){
if ($Arr['gender'] === "m"){
//Is Male
#$Return_Arr['M'][$Arr['rname']] ++; // Message supressed due to returning undefined index warnings... Which because of not using isset().. Will still work
}elseif ($Arr['gender'] === "f"){
// Is Female
#$Return_Arr['F'][$Arr['rname']] ++; // Message supressed due to returning undefined index warnings... Which because of not using isset().. Will still work
}
}
return $Return_Arr;
}
$Array = array (
array(
"gender" => "m",
"rname" => "c"
),
array(
"gender"=> "f",
"rname" => "d"
),
array (
"gender" => "f",
"rname" => "a"
),
array (
"gender" => "f",
"rname" => "x"
),
/* Array shortened for exampling purposes */
);
$Array_Count = Array_Counter($Array);
Using the function as followed
echo "<pre>";
print_r($Array_Count);
echo "</pre>";
Returns:
Array
(
[M] => Array
(
[c] => 1
[j] => 1
[g] => 1
[d] => 1
)
[F] => Array
(
[d] => 3
[a] => 1
[x] => 1
)
)
