限制多维数组响应

Question

Having 3 multidimensional arrays, to whom I do a foreach how can I limit the multidimensional response inside foreach from X items to lets say 20.

Code:

$i = 0;
foreach ($value->channel->item as $item)
{
    $data['data'][$keySection]['item1'][$i]['url']   = $item->url;
    $data['data'][$keySection]['item1'][$i]['title'] = $item->title;
    $data['data'][$keySection]['item1'][$i]['img']   = $item->thumb;
    $i++;
}

where $value is contained within

foreach ($homeData as $keySection => $valueSection)
{
    foreach($valueSection as $key => $value)
    {
        switch ($key)
        {

I've tried aplying some fors both within foreach ($value->channel->item as $item) as outside but I just can't get it to work properly, I get either doubled results or not working at all.

How can I make this work??

Edit: $i has nothing to do with it... I need to limit $value->channel->item where item contains X results

Edit2: $i is for $homeData where $homeData contains three values and each and one of those will later contain 3 different values of $value->channel->item so if item contains 20 results, will be 3x20 = 60 and $i is ment to separate each 20 results...

Edit3: ok, now I get it... sorry for the misunderstanding

Answer 1

After you start the foreach, add:

if($i > 19) {
    break;
}

This checks if $i is greater than 19 (which means 20 iterations) and then breaks this foreach loop. More information about break, here.
