It is easy. I agree with whoever said string functions were a better
solution, regexp is overkill unless there is more variaiton in the data
than what was presented. That said, here are some possibilities; all
but the first assume that the "--" is always there:
- If the lengths are constant just use substr to pull out the
first 11 characters.
- Find the "--" with strpos and then use that in a substr call to
take just the part to the left.
- Use explode to separate the string at the "--" or "--2c".
- For two numeric strings separated by a dash use a regexp
approach something like this:
if (preg_match("/^(\d*-\d*)--2c/", $string, $matches))
$left_part = $matches[1];
