array_slice但是对于图像php

Question

i have written this code

  <?php
        $a = Meme::all();
        $b = count($a);
        for($i=$b;$i<$b-3;$i--)  {
    ?>      <div class="col-sm-6"><img class="lazy" data-src="<?php echo $a[$i]->path; ?>" /> </div>
    <?php
    }?> 

i want to output the last 3 memes(images) but this for loop doesn't work. So i found something that is called array_slice and i wanted to use it but everyone was using print_r but in this case i don't need it. So any suggestions?

Answer 1

Store those 3 elements of array $a in a new array $b by using array_slice:

<?php    
    $a = Meme::all();
    $b = array_slice($a, 3);

    for ($i = 0; $i < 3; $i++){
?>
    <div class="col-sm-6"><img class="lazy" data-src="<?php echo $b[$i]->path; ?>" /> </div>
<?php
    }
?>
