comment changer l'index d'un array
Bonjour à tous,
Je contruit une array de cette manière
Code:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15

while($row = $sql_result->fetch_assoc()){
//print_r($row);
$id_colect = (int)$row['id_collection'];
$collections[$id_colect]['field'] = $row['field_name'];
$collections[$id_colect]['station'] = $row['station_name'];
$collections[$id_colect]['id_station'] = $row['id_station'];
$collections[$id_colect]['time'] = $row['collection_date'];
$collections[$id_colect]['collection'] = $row['id_collection'];
if(!array_key_exists($row['sensor_type_longname'], $collections[$id_colect])){
$collections[$id_colect][$row['sensor_type_longname']] = $row['value'];
}
} |
Ca fonctionne très bien.
Le problème est l'index de l'array comment par 1. Vu qu'elle dépend de l' id_collect, il peux commencer par 1 comme par 50. Cette manière de procéder me permets de faire un tableau multidimentionnel par id des collection de mesure et je ne souhaite pas changer ceci.
Par contre, j'aimerais que mes index change et commence de 0.
Si je loop $collection
Code:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17

echo "<ul>";
foreach($collections as $t => $tt){
echo "<li>collection id: ".$t.": ";
echo "<ul>";
foreach($tt as $u => $uu){
echo "<li>";
echo $u." => ".$uu;
echo "</li>";
}
echo "</ul>";
echo "</li>";
}
echo "</ul>";
echo "<ul>"; |
Il m'affiche ceci

et faire e sorte que mon nouveau array "rafraichi" commence toujours par 0
Est-ce qu'il y a une fonction que peut réinitier mes index pour partir de 0?
Merciiii
