Unset first element of array that don't know first item's key value

Question

I'm getting list of image using foreach, but I don't want to display first image of array, but I don't know how to make it works. Here my code:

$portfolio_gallery_image = get_post_meta( get_the_ID(), "portfolio_gallery_image", true );

<div class="folio-gallery grid-masonry clearfix">
    <?php
    foreach ( $portfolio_gallery_image as $key => $image ){
    ?>
        <a class="folio-item col-3 ndSvgFill grid-item" href="<?php echo esc_url($image) ?>">
            <img src="<?php echo esc_attr($image) ?>" alt="portfolio">
        </a>
    <?php } ?>
</div>

This is array

Array

You can do like this,

<?php

function custom_function(&$arr)
{
    list($k) = array_keys($arr);
    $r = array($k => $arr[$k]);
    unset($arr[$k]);
    return $r;
}
custom_function($portfolio_gallery_image);
foreach ($portfolio_gallery_image as $key => $image) {

    ?>
    <a class="folio-item col-3 ndSvgFill grid-item" href="<?php echo esc_url($image) ?>">
        <img src="<?php echo esc_attr($image) ?>" alt="portfolio">
    </a>
<?php } ?>

array_shift Shift an element off the beginning of array.

Thank you. I got this error: `Warning: Invalid argument supplied for foreach()` – The Hung Apr 19 '17 at 05:07
if your array is like e.g. [a,b,c,d] then array_shift will skip a and then array will have [b,c,d] this is how it works. May I know how your array looks like, until n unless I wont get idea regarding manipulation of your array – Rahul Apr 19 '17 at 05:11

Try below code to remove first key/value from array before for each in your code.

$new_image_array = array_shift($portfolio_gallery_image);
