如何在数组中添加新项目 [英] How to add a new item inside an array

问题描述

这是我在PHP中打印出的数组

This is a array that i printed out in PHP

Array ( [0] => Array ( [friend_id] => 1 [name] => parker[email] => [e-mail])[1] => Array ( [friend_id] => 2 [name] => peter [email] => [e-mail]) )

我能知道如何在php中使用循环在像这样的数组内添加新项/参数吗?

Can i know how to use loop in php to add a new item/param inside the array like this

Array ( [0] => Array ( [friend_id] => 1 [name] => parker[email] => [e-mail] [NEWOBJECT] => newvalue)[1] => Array ( [friend_id] => 2 [name] => peter [email] => [e-mail] [NEWOBJECT] => newvalue) )

推荐答案

无需循环，您只需添加以下内容即可:

No need for loop you can just add by this:

<?
 $arr =  Array ( [0] => Array ( [friend_id] => 1 [name] => parker[email] => [e-mail])[1] => Array ( [friend_id] => 2 [name] => peter [email] => [e-mail]) );

 $arr[0]['NEWOBJECT'] = 'blablabla';
 $arr[1]['NEWOBJECT'] = 'blablabla';
?>

但是当您必须这样做两次以上时，这将有所帮助:

But when you have to do this more than 2 times of course this would help:

<?

$arr =  Array ( [0] => Array ( [friend_id] => 1 [name] => parker[email] => [e-mail])[1] => Array ( [friend_id] => 2 [name] => peter [email] => [e-mail]) );

 foreach($arr as $key => $value){
    $arr[$key]['NEWOBJECT'] = 'blablabla';
 }

?>
