Pixmeister on "[Plugin: Polylang] include/exclude sync of AFC Repeater Fields"

I found that code in Advanced Custom Fields Repeater to access the rows.

<?php

$rows = get_field('repeater_field_name' ); // get all the rows
$first_row = $rows[0]; // get the first row
$first_row_image = $first_row['sub_field_name' ]; // get the sub field value

// Note
// $first_row_image = 123 (image ID)

$image = wp_get_attachment_image_src( $first_row_image, 'full' );
// url = $image[0];
// width = $image[1];
// height = $image[2];
?>
<img src="<?php echo $image[0]; ?>" />

But i didn't found out how to use it for the array merging.
