Expectations
array( 'name' => 'SUB CAT 1',
'details' => 'AAAAAAAAA',
'image_name'=>'2.jpg'
);
array( 'name' => 'SUB CAT 2',
'details' => 'BBBBBBB',
'image_name'=>'2.jpg'
);

This can be done with a simple foreach() loop -
$newArray = [];
foreach($_POST["subcatagory"] as $key => $value) {
$newArray[] = array("name" => $_POST["subcatagory"][$key],
"details" => $_POST["subCat_Detais"][$key]);
}
As #CharlotteDunois mentioned, you could also use an for() loop, as long as you have sequential keys, with no keys missing -
$newArray = [];
for($i=0;$i<count($_POST["subcatagory"]);$i++) {
$newArray[] = array("name" => $_POST["subcatagory"][$i],
"details" => $_POST["subCat_Detais"][$i]);
}
