PHP REGEX - text to array by preg_split at line break

Question

EDITED:

need help on split Array

array example:

 array (

           [0] =>
            :some normal text
            :some long text here, and so on... sometimes 
            i'm breaking down and...
            :some normal text
            :some normal text
        )

ok, now by using

preg_split( '#\n(?!s)#' ,  $text );

i get

[0] => Array
        (
            [0] => some normal text
            [1] => some long text here, and so on... sometimes
            [2] => some normal text
            [3] => some normal text
        )

I want get this:

[0] => Array
        (
            [0] => some normal text
            [1] => some long text here, and so on... sometimes i'm breaking down and...
            [2] => some normal text
            [3] => some normal text
        )

what Regex can get the entire line and also split at line break!?

Doesn't sound like you want to split on newlines at all but rather `TEXT:` — webbiedave, Apr 26 '10 at 19:49
ok, just for make things clear, i need a REGEX that donn't cut off the line but keep it fully! all other method seen here are not for me! ;-) — Luca Filosofi, Apr 26 '10 at 19:51
forget the TEXT# , just consider my Regex, it is working well, but it split also the long string, i need it to keep the long lines fully!!! — Luca Filosofi, Apr 26 '10 at 20:08
ok, i have updated once more time my question, the delimiter is a **colon** **:** what is the regex i'm finding!? ;-) — Luca Filosofi, Apr 26 '10 at 21:14

"line break" is ill-defined. Windows uses CR+LF (\r\n), Linux LF (\n), OSX CR (\r) only.

There is a little-known special character \R in preg_* regular exceptions that matches all three:

preg_match('/^\R$/', "\r\n"); // 1

Here's an example that works, even if you have a colon character embedded inside the string (but not at start of the line):

$input = ":some normal text
:some long text here, and so on... sometimes
i'm breaking: down and...
:some normal text
:some normal text";

$array = preg_split('/$\R?^:/m', $input);
print_r($array);

result:

Array
(
    [0] => some normal text
    [1] => some long text here, and so on... sometimes
           i'm breaking: down and...
    [2] => some normal text
    [3] => some normal text
)

i don't need to split **TEXT:** this is just an example for delimit each line!!!!!! – Luca Filosofi Apr 26 '10 at 20:13
Ok, so, which character exactly delimits the lines? – Milan Babuškov Apr 26 '10 at 21:05

file() reads a file into an array.

Thanks posting something useful, non-intuitive, and answers the needs of many similar questions. Even if it ignores the stated requirements. – SamGoody Feb 20 '12 at 08:07

If you split the array on the : character..

print_r(preg_split('/:/', $input));
