Smarty/PHP repeat printing of String x times

Hello,

we have got an array of items, each of them having an attribute "depth". We would like to repeat printing a string, e.g. "--" depth-times in the template.

Consider the following example
root
-- node: depth 1 (-> repeated 1 time)
-- node: depth 1 (-> repeated 1 time)
---- node: depth 2 (-> repeated 2 times)
------ node: depth 3 (-> repeated 3 times)

.. etc.

Any suggestions?

Something like this?
$temp = array(array(1,"-"),array(2,"--"),array(3,"---"));

foreach ($temp as $v ) {
	for ( $i = 0; $i < $v[0]; $i++) {
		print $v[1];
	}
}

Hi, sorry for now being specification enough. We were looking for a Smarty way of doing this. First we'd like to Know whether there is à built in Smarty way to do this,  or à performant modifier.

Thanks!

You could use str_repeat.

Suppose you have an array $node that looks like this:
Array(2):
  'value' => "some value"
  'depth' => 2
echo str_repeat($node['value'], $node['depth']);

For only printing '--' characters you can use string_format as well. But it is a bit hack not a normal usage. If a $depth variable exists and assuming you want to print '--' for each depth level. You can write as the following :
{assign var=depth_str value='%\'-'|cat:$depth*2|cat:'s'}
{''|string_format:$depth_str}
