Hi @bart-gopnik

In this case, you need to create a function to loop through the returned fields and its values. Here’s an example how to do it:

// Create function that will loop through the array
function print_array_value($value){
    if( is_array($value) ){
        foreach( $value as $k => $the_value ){
            echo '<' . $k . '>' . PHP_EOL;
            print_array_value($the_value);
            echo '</' . $k . '>' . PHP_EOL;
        }
    } else {
        echo $value . PHP_EOL;
    }
}

// Loop through the fields here
foreach($fields as $field){
    
    echo '<' . $field['name'] . '>' . PHP_EOL;
    
    // Check if this is a repeater or not
    print_array_value($field['value']);
    
    echo '</' . $field['name'] . '>' . PHP_EOL;
}

Because this is more related to PHP than ACF, kindly get in touch with PHP community for more support.

I hope this helps 🙂
