Definitely interesting. We probably would want to make it flexible
enough to handle any number constants on the same line. (your code
makes us *more* flexible than we are, but that next step would "finish
out" the problem). Feel free to modify it as necessary, or I'll take
a look when I get a free second and propose the solution to the list.
Hi,
this snippet allows replacement of any number of constants.
This could be done cleaner by using the &count parameter, but since it's
only available since PHP 5.1.0, I used a more backwards friendly solution.
-----------------------------
public static function & replaceConstants ($value)
{
// needed for first loop
$newvalue = $value;
do
{
$value = $newvalue;
$newvalue = preg_replace_callback(
'/\%(\w+?)\%/',
create_function(
'$match',
'$constant = $match[1]; ' .
'return (defined($constant) ? constant($constant) :
"%".$constant."%");'),
$value,
1);
} while ($newvalue != $value);
return $value;
}
-----------------------------
Best Regards,
Johan
