Question

i want to write a function that prints multi-dimensional objects which are text (or integers, etc.) into <span></span> tags and arrays into unordered lists.

how do you make the function work recursively so that it prints everything regardless of what level it’s at in the object?

thanks!

Objects can be treated as arrays – try using foreach….

 function dump($obj, $prefix='')
 {
     foreach ($obj as $key=>$val) {
         print "$prefix attribute $key is a " . gettype($val) . "=";
         switch (gettype($val)) {
            case 'string':
            case 'boolean':
            case 'resource':
            case 'double':
            case 'NULL':
                var_export($val,true) . "\n";
                break;
            case 'object':
                print "(class=" . get_class($val) . ")";
            case 'array':
                print "(";
                dump($val, $prefix . '  ');
                print ")\n";
            default:
                print "????\n";
         }
     }
 }
