构造包含许多数组的数组[关闭]

Inside a foreach loop, I am returning an array ($followerPosts).

foreach($myfollowers['entities'] as $myfollower)
{
     $followerPosts=$this->displayPostsAction($myfollower->getFollower());
}

I need to have at the end one one big array containing all the $followerPosts arrays.

$bigArray = array();
foreach($myfollowers['entities'] as $myfollower)
{
     $followerPosts=$this->displayPostsAction($myfollower->getFollower());
     $bigArray[] =  $followerPosts;
}

OR

 $bigArray = array();
    foreach($myfollowers['entities'] as $myfollower)
    {
         $bigArray[] =$this->displayPostsAction($myfollower->getFollower());

    }

You can declare an array before the loop, then use array_merge on each iteration

or array_push, it depends on what you want to do

Use array_merge to put all of them into one array like this:

$big = array();
foreach($myfollowers['entities'] as $myfollower)
{
     $big = array_merge($big, $this->displayPostsAction($myfollower->getFollower()));
}

You have to add them to the array.

$followerPosts = array()

foreach($myfollowers['entities'] as $myfollower)
{
     //$followerPosts=$this->displayPostsAction($myfollower->getFollower());
     $followerPosts[]=$this->displayPostsAction($myfollower->getFollower());

}

print_r(followerPosts)

For the purpose the best tool, I think, is the array_map function:

$followerPosts = array_map(function($f) {
    return $this->displayPostsAction($f->getFollower());    
}, $myFollowers['entities']);

var_dump($followerPosts);
