You can try to do this way :
<?php
$firstArray = array();
foreach($bigArray as $key => $array) {
$value = $array[4]; //fetch the 4th indice
if(! isset($firstArray[$value])) {
$firstArray[$value] = array();
}
$firstArray[$value][$key] = $value;
}
$secondArray = array();
foreach($firstArray as $name => $array) {
foreach($array as $key => $info) {
$value = $bigArray[$key][2]; //fetch the 2nd indice
if(! isset($secondArray[$value])) {
$secondArray[$value] = array();
}
$secondArray[$value][$key] = $value;
}
}
