How to get a data in a PHP cell

So, I need to get the cell value of the time in foreach, but since the vector was re-organized with asort () , I do not know how to get this value. If I put $ vector_Distance [0] , it would take the first cell (after it is organized), but cell 0 (Note: I can not re-organize by changing the key of each cell, this key is related to another vector that has cpf related that distance). (Note: It is very urgent).

// foreach com um vetor
 foreach ($tecnicos[2] as $tecnico):
     // $tecnicos[0] é o vetor onde estão as distâncias, elas estão em ordem crescente
     $vetorComDistancia = $tecnicos[0];
     //no caso aqui eu pegaria a distância da vez,
     $distanciaDaVez = $vetorComDistancia[];
