I have been plauged for a few days by this, can anyone see a problem with
this function??

function printByType($string, $mode)
{
(string) $string;
$lengths = array(

Re: Regexp and Arrays

There can be a problem. But do you see a problem?? if yes. what is it?
May be we can find the solution.

Re: Regexp and Arrays

On a quick glance I don't think you are doing the casting correctly. =
For example, you have stuff like:

(string) $string;=20

and=20

(string) $key;
(int) $val;

and=20

(int) $length_value =3D $match[1];

and the casted value is not being saved anywhere.

I believe it should be something like $string =3D (string) $string; in =
order to assign the casted value back to the variable. In the third =
example, you probably meant $length_value =3D (int) $match[1];

I think part of the problem may lie in the use of variables in regular
expressions. I am trying to use the perl-style preg_match(), but the regular
expression values that it checks on each iteration of the foreach loop
checks for a different value (hence, the use of a variable).
