strings 'n stuff

[noeffred]

I want to format a string so it can easily be emailed. I'm quite stuck with the following:

I get a long string seperated by ":" (no quotes in the string). I now need to insert "\n" after every !second! ":" .
After (or before?) that I need to erase every empty pair ("1234:" in the example below) from the string..
I've been trying for some hours now but I haven't found any really good solution yet.

i.e.:
1234::4321:12:123:2 is my string

that's what it should look like:
4321:12
123:2

so if anyone could pls. help me out here..

Something like this is probably a good way to do it.

$temparray = explode(":", $inputarray);
for ($i = 0; $i < sizeof($temparray); $i += 2) {

echo($temparray[$i].":".$temparray[$i+1]."\r\n");
}

That would still print the first item too, so you'd probably have to start at $i=1.

Also, be carefull about "\r\n" some programs look for just the "\n", and they either misinterpret the "\r\n" for "\n\n" or you are left with "\r" at then end of your strings, which can cause some major headaches. :-)
