I am trying to extract a substring. I need some help with doing it in PHP.
Here are some sample strings I am working with and the results I need:
home/cat1/subcat2 => home test/cat2 => test startpage => startpage
I want to get the string till the first
/, but if no
/ is present, get the whole string.
substr($mystring, 0, strpos($mystring, '/'))
I think it says - get the position of
/ and then get the substring from position 0 to that position.
I don't know how to handle the case where there is no
/, without making the statement too big.
Is there a way to handle that case also without making the PHP statement too complex?
$arr = explode("/", $string, 2); $first = $arr;
In this case, I'm using the
limit parameter to
explode so that php won't scan the string any more than what's needed.
