Array from query results php inside while - php

Question

I have this code, which is parcially working... I'm trying to do this:
Array
(
[servicio_id 1] => Array
(
[peticion_id 1] => Array
(...)
[peticion_id 2] => Array
(...)
[peticion_id 3] => Array
(...)
)
[servicio_id 2] => Array
(
[peticion_id 1] => Array
(...)
[peticion_id 2] => Array
(...)
[peticion_id 3] => Array
(...)
)
)
So each [servicio_id] has it's [peticion_id] with its own values... the problem is that my code actually set the same values inside every [peticion_id] array, increasing it's size as long as the loop is running... Any advice on how to clear and start again the [peticion_id] array once the [servicio_id] is finished?
Thank you in advice
while($row = sqlsrv_fetch_array($sqlQuery)) {
if($row['peticion_id'] == 0) {
$ok[] = round($row['valor'], 3);
if($row['media_ok'] == null) {
$medias_ok = array("0", "0", "0", "0");
} else {
$medias_ok = Umbrales::getValues($row['media_ok'], $row['media']);
}
$max_ok[] = $medias_ok[1];
$min_ok[] = $medias_ok[0];
}
if($row['peticion_id'] == 1) {
$ko[] = round($row['valor'], 3);
if($row['media_ok'] == null) {
$medias_ko = array("0", "0", "0", "0");
} else {
$medias_ko = Umbrales::getValues($row['media_ok'], $row['media']);
}
$max_ko[] = $medias_ko[2];
}
if($row['peticion_id'] == 2) {
$rt[] = round($row['valor'], 3);
if($row['media_ok'] == null) {
$medias_rt = array("0", "0", "0", "0");
} else {
$medias_rt = Umbrales::getValues($row['media_ok'], $row['media']);
}
$max_rt[] = $medias_rt[3];
}
$datos[$servicios[$row['servicio_id']]] = array(
"OK" => $ok,
"KO" => $ko,
"RT" => $rt,
"UMBRAL_MIN_OK" => $min_ok,
"UMBRAL_MAX_OK" => $max_ok,
"UMBRAL_MAX_KO" => $max_ko,
"UMBRAL_MAX_RT" => $max_rt
);
}

You need to clear the array on each loop.
After you while it should read:
while($row = sqlsrv_fetch_array($sqlQuery)) {
$ok = array();
$ko = array();
$rt = array();
$min_ok = array();
$max_ok = array();
$max_ko = array();
$max_rt = array();
if($row['peticion_id'] == 0) {
