问题描述

需要将foreach循环中的值存储到数组中,需要帮助。下面的代码不起作用,只存储最后一个值,尝试$ items。= ...,但是这不是伎俩,任何帮助将不胜感激。

<$ ($ group_membership as $ i => $ username){
$ items = array($ username); $ p $ <?php
foreach
}

print_r($ items);
?>


解决方案

声明 $ items 数组,并使用 $ items [] 将项添加到数组中:

  $ items = array(); 
foreach($ group_membership as $ username){
$ items [] = $ username;
}

print_r($ items);


Need to store values from foreach loop into an array, need help doing that. 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.

<?php
foreach($group_membership as $i => $username) {
 $items = array($username);
}

print_r($items);
?>

解决方案

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);
