PHP - How to combine arrays into one array in while loop?

问题

I have this code which gives me post_permalink in a while loop.

<?php 
  $value[] = array();
    while ($the_query->have_posts()) : $the_query->the_post()
                $value[] =array(
                    'post_permalink' => get_permalink()
                );

 endwhile; ?>

Now the thing is that I'm getting the links as

    Array ( [0] => Array ( [post_permalink] => link ) 
            [1] => Array ( [post_permalink] => link ) 
            [2] => Array ( [post_permalink] => link ) 
            [3] => Array ( [post_permalink] => link ) )

The way I want it to be:

        Array ( [post_permalink] => link  
                [post_permalink] => link 
                [post_permalink] => link 
                [post_permalink] => link  )

i.e: All of the links in one array instead of four subarrays. Please help!

The example of what you want is not possible as array keys are unique.

You probably want something like:

$value['post_permalink'][] = get_permalink();

回答2:

You can't have an array the way you want it because each array key must be unique. This will work:

$values = array();
while($the_query->have_posts()) : $the_query->the_post();
    $values[] = get_permalink();
endwhile;

foreach($value[0] as $k=>$v)
   $result[$k]=$v
