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

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);

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);
?>

Just to save you too much typos:

foreach($group_membership as $username){
        $username->items = array(additional array to add);
    }
    print_r($group_membership);

Try

$items = array_values ( $group_membership );

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. :)

$items=array(); 
$j=0; 

foreach($group_membership as $i => $username){ 
    $items[$j++]=$username; 
}

Just try the above in your code .

Use

$items[] = $username;

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