How to store values from foreach loop into an array? - php

Question

Need to store values from foreach loop into an array, need help doing that.
The code below does not work, only stores the last value, tried $items .= ..., but that is not doing the trick either, any help will be appreciated.
foreach($group_membership as $i => $username) {
$items = array($username);
}
print_r($items);

Answer 1

Declare the $items array outside the loop and use $items[] to add items to the array:
$items = array();
foreach($group_membership as $username) {
$items[] = $username;
}
print_r($items);

Answer 2

Use
$items[] = $username;

Answer 3

Try
$items = array_values ( $group_membership );

Answer 4

<?php
$items = array();
$count = 0;
foreach($group_membership as $i => $username) {
$items[$count++] = $username;
}
print_r($items);
?>

Answer 5

You can try to do my answer,
you wrote this:
<?php
foreach($group_membership as $i => $username) {
$items = array($username);
}
print_r($items);
?>
And in your case I would do this:
<?php
$items = array();
foreach ($group_membership as $username) { // If you need the pointer (but I don't think) you have to add '$i => ' before $username
$items[] = $username;
} ?>
As you show in your question it seems that you need an array of usernames that are in a particular group :) In this case I prefer a good sql query with a simple while loop ;)
<?php
$query = "SELECT `username` FROM group_membership AS gm LEFT JOIN users AS u ON gm.`idUser` = u.`idUser`";
$result = mysql_query($query);
while ($record = mysql_fetch_array($result)) { \
$items[] = $username;
}
?>
while is faster, but the last example is only a result of an observation. :)

Answer 6

This is how you do it:
foreach($orders as $item){
$transactionIds[] = $item->generated_order_id;
}
dump($transactionIds);
This is assuming $orders collection has a field called 'generated_order_id'.

Answer 7

$items=array();
$j=0;
foreach($group_membership as $i => $username){
$items[$j++]=$username;
}
Just try the above in your code .

Answer 8

Just to save you too much typos:
foreach($group_membership as $username){
$username->items = array(additional array to add);
}
print_r($group_membership);

Answer 9

this question seem quite old but incase you come pass it, you can use the PHP inbuilt function array_push() to push data in an array using the example below.
<?php
$item = array();
foreach($group_membership as $i => $username) {
array_push($item, $username);
}
print_r($items);
?>
