I am trying to create an array which will have two key/value pairs for each user. I would like to add their user ID as well as their name.
Currently I have this:
<?php
$userArray = array();
foreach ($users as $user) {
array_push($userArray, $user->ID, $user->name);
}
print_r($userArray);
?>
This gives me the following:
Array ([0] => 167 [1] => Bill [2] => 686 [3] => Jim [4] => 279 [5] => Tom)
However, to make it easier to read and work with, I would prefer that it shows user_id
and user_name
as the keys, rather than just the index. I believe this is what's called a multidimensional array and would look more like this:
Array (
0 => array(
'user_id' => 167,
'user_name' => 'Bill'
),
1 => array(
'user_id' => 686,
'user_name' => 'Jim'
),
2 => array(
'user_id' => 279,
'user_name' => 'Tom'
)
)
My question is how would I build an array like this within my foreach
loop?
您只需要创建新数组并将其添加到$userArray
,但我使用[]
而不是array_push()
......
$userArray[] = [ 'user_id' => $user->ID, 'user_name' => $user->name];
you should be pushing a new array, like this :
<?php
$userArray = array();
foreach ($users as $user) {
array_push($userArray, ['user_id' => $user->ID, 'user_id' => $user->name]);
}
print_r($userArray);
?>
