I have an array $people
. When I do print_r($people)
, I get the following results:
[people] => Array
(
[500] => Array
(
[firstName] => Fred
[age] => 19
)
[501] => Array
(
[firstName] => Bob
[age] => 12
)
[502] => Array
(
[firstName] => Steve
[age] => 52
)
)
I want to change all the keys to look more "normal", starting at 0, then 1, 2 etc. How can I achieve this? To clarify, I want the resulting array to look like this:
[people] => Array
(
[0] => Array
(
[firstName] => Fred
[age] => 19
)
[1] => Array
(
[firstName] => Bob
[age] => 12
)
[2] => Array
(
[firstName] => Steve
[age] => 52
)
)
内置函数array_values()将仅从数组中获取值,而忽略键,而是返回从零开始重新编号的数组。
$people = array_values($people);
Simply like this:
foreach ($people as $value) {
$people_new[] = $value;
}
Try this
$people['people'] = array_values($people['people']);
print_r($people);
