Question

PHP

There is such a device, how to get only 3 first out of it

<?php foreach ($elements as $element): ?>
    
    <?php foreach ($element as $images): ?>
        
        <?php foreach ($images as $image): ?>
        	<?=$image['thumb_src']?>
        <?php endforeach; ?>
        
        
        
    <?php endforeach; ?>
    
<?php endforeach; ?>

Answer 1

foreach (array_slice($images, 0, 3) as $image) {
   $image['thumb_src']
}

Answer 2

First, the array you are interested in iterating can be accessed without nested loops, like this: $element[0][0][0]
If you need to output three elements anyway and there are always these three elements, then the easiest way is to print them without iterating:

echo $element[0][0][0]['thumb_src'].$element[0][0][1]['thumb_src'].$element[0][0][2]['thumb_src'];

If with minimal changes it is your code, then like this:

<?php
foreach ($elements as $element)
{
   foreach ($element as $images)
   {
      $i = 1;
      foreach ($images as $image)
      {
         echo $image['thumb_src'];
         if($i++ >= 3)
         {
            break;
         }
      }
   }
}
?>

But there are big questions about what else lies in this array, otherwise your cycles can output something else. Read something on the basic syntax of the language.
