I have a string which looks like this:
21/04/2014,16:57:28,19,0,2021/04/2014,16:57:48,19,0,20
I would like to split it so that I get something like the following:
21/04/2014,16:57:28,19,0,20
21/04/2014,16:57:48,19,0,20
I have tried using php's substr which I thought was giving results but it duplicated this '21/04/2014,16:57:48,19,0,20' twice.
$data3 = array(substr($data1, -27), substr($data1, 27));
Even tried a regex with no luck.
Elon Than's answer is the perfect solution if, as he states, the length is constant. However, I just thought I'd add this solution in case (for example) the '19' could also be '3' (or whatever):
preg_match_all("/\d{2}\/\d{2}\/\d{4}\,\d{2}:\d{2}:\d{2},\d{1,2},\d{1},\d{2}/", $string, $matches);
var_dump($matches[0]);
Notice the \d{1,2} will include any number that is 1 or 2 digits.
If length of parts you want to get is constant you can use str_split function with second parameter.
$data = str_split($string, 27);
$data3 = array(substr($data1, 0, 27), substr($data1, 27));
