I want to split the content of a text file by ; and ::
#STA:00007;TM:01/30/2016,13:48:03;
Desired output:
STA TM
00007 01/30/2016,13:48:03
This should separate your values.
preg_match('/^#STA:(\d+);TM:([\d\/:,]+);$/', '#STA:00007;TM:01/30/2016,13:48:03;', $matches);
$sta = $matches[1];
$tm = $matches[2];

If that part is in the middle of a string take out the anchors ^$.
\d is a number 0-9.+ is a quantifer meaning 1 or more of the preceding character/group/class.[] is a character meaning the characters inside are allowed.^$ are anchors, matching the start and end of the string./s are delimiters.() are capture groups (what is inside is captured).
Everything else in that regex is literal.
