Hi,
I'm trying to write a function that takes a string and splits this into 3
distinct sections for a project I'm working on.
This string in question has the following formet:
"% 999990008312?;0 008312999990000 ?"
The important bits i want to extract are the 1st and second numbers. In this
example that is 99999 and 0008312. The sequence of 9's has a fixed length
of 5 chars and the other number is whatever follows those 5 until the
questionmark.
My idea was to use explode to get the string up to the "?" and the use
substr() to split the remaining string into the bits I want. Not being the
greatest coder in the world I came up with this ($card_string is from the
function call):
$card_string = trim($card_stri ng, "%"); // get rid of the first char and
all those annoying spaces
$card_data = explode("?", $card_string);
$card_ver = substr($card_da ta[0],0,5); // first 5 chars of string
$card_id = substr("$card_d ata[0]",6); // all other chars
I expected $card_ver to become "99999" and $card_id to contain "0008312",
BUT what I actually get is $card_ver empty and $card_id "9999900083 12". If
I insert a line $card_data[0] = "9999900083 12" this actually does happen,
but if I knew the string's content, why would I write a function?
Typecasting $card_data[0] to type string with either
'$card_ver_stri ng_typed = (string) substr($card_da ta[0],0,5);' or
$card_data_stri ng = "$card_data[0]" don't help either.
Am I overlooking something, is this a very weird limitation of PHP or is
there just an easier way of doing this alltogether?
All help more than welcome!

Hope this doesn't show up twice anywhere, newsreader gave me a really big
error message when I tried to post...
