将数组的所有元素传递给单个数组

Question

我在获取此输出时遇到问题。我有一个像这样声明的数组：

$category = array(1,2,4,5,10); //category_ids

现在，我想将它传递给另一个参数：

$parameter = array(
         array('category_id' => 1),
         array('category_id' => 2),
         array('category_id' => 4),
         .
         .
         . 
);

怎么做？

喜欢这个：

<?php
$category = array(1,2,4,5,10); //category_ids

foreach($category as $c){
    $parameter[] = array('category_id' => $c);
}

print_r($parameter);

// Output:
//Array ( [0] => Array ( [category_id] => 1 ) 
//[1] => Array ( [category_id] => 2 ) 
//[2] => Array ( [category_id] => 4 ) 
//[3] => Array ( [category_id] => 5 ) 
//[4] => Array ( [category_id] => 10 ) )
