Hi @bart-gopnik

The easiest way would be checking if the current key is a number or not like this:

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

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;
    
}

I hope this makes sense 🙂
