内部数组foreach循环 [英] Foreach loop inside array

问题描述

我试图创建一个数组里的数组，使用for循环 - 这里是我的code：

I'm trying to create an array inside an array, using a for loop - here's my code:

    array(
    'label' => 'Assign to user',
    'desc' => 'Choose a user',
    'id' => $prefix.'client',
    'type' => 'radio'
    'options' => array( 
        foreach ($clients as $user) {
         $user->user_login => array (  
            'label' => $user->user_login,  
            'value' => $user->user_login,
            ), 
        }
        )
    )

不幸的是这给了我一个

Unfortunately this gives me a

解析错误：语法错误，意想不到的T_CONSTANT_ENCAPSED_STRING，
  预计'）'。

"Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING, expecting ')'"

有关该行：

'options' => array( 

我在一个有点损失，以什么错误 - 任何帮助是非常AP preciated。 $客户在其他地方定义，所以这是没有问题的。

I'm at a bit of a loss as to what has gone wrong - any help is much appreciated. $clients is defined elsewhere, so that is not the problem.

推荐答案

这是无效的语法。你必须首先构建阵列的父部分。然后在子阵列的东西与foreach循环添加：

That's invalid syntax. You'd have to build the "parent" portions of the array first. THEN add in the sub-array stuff with the foreach loop:

$foo = array(
    'label' => 'Assign to user',
    'desc' => 'Choose a user',
    'id' => $prefix.'client',
    'type' => 'radio',
    'options' => array()
);

foreach ($clients as $user) {
    $foo['options'][] = array (  
        'label' => $user->user_login,  
        'value' => $user->user_login,
    );
}
