Changing a template with an array

[dougmcc1]

This array takes input from a form and inserts it in a template:

$fields_to_parse=array("string1","string2","string3"); 

while (list($null,$field)=each($fields_to_parse)) { 
  $template=str_replace("[[".$field."]]",strip_tags($_POST[$field]),$template); 
}

So if I enter 'Foo' into <input name="string1">, then in the template [[string1]] is replaced with 'Foo'.

How do I acheive the same effect with variables instead of form input?

I want to be able to replace [[string1]] with $string1.
Thanks.

$template=str_replace("[[".$field."]]", $string1 );
