text betwen slashes into radio buttons

Hi,

I need to analyze a string and get the text between, before, and after the forward slashes..

The string will always look something like this, but will vary:

$str = "I will go to the store with <# one/two/three #> people."

Then I need to create a form with radio buttons for each choice. In this case (one, two, or three).

The text between the <# ... #> could be different every time, and with uknown amount of forward slashes.

Here is what I have so far but it doesn't work.

Code to find if there are slashes:

Code: Select all

preg_match_all( '/([/]+)/',$str,$matches);
Code to create html form ..

Code: Select all


$i = 0;
$html  = '<form>';

foreach ($matches[0] as $match){

     if ($pos = strpos( $str,$match ) ) === false )
          continue;
     }

     $html .= '<input type="radio" name="place-' . $i . '" value=". $match . '" />&nbsp;&nbsp;';

} 

$html .= '</form>';

Its not working as needed. I'm not sure how to create radio button choices for the words (one, two, three).

Thanks
