pref_split function

[mikerh9]

I'm using the preg-split function. This function match a string and if it match "-" it creates a string that it goes before "-" and I need the string that is after the "-". Any ideas how to make it work?

preg_split("/-/", $temp, -1, PREG_SPLIT_NO_EMPTY);

if you just want to split a string why use preg_split?

list($string1,$string2) = split("-",$temp);

Well, for one thing, preg_split() would be slightly faster than split(). Much faster than both, though, would be explode().

funny, I always thought it was the opposite. Can't recall where I may have read that or heard that, but I thought the pcre functions were slightly slower.

mikerh9:
As for the problem at hand, you need to dump the output from preg_split into an array or a list of variables.

$data = preg_split("/-/", $temp, -1, PREG_SPLIT_NO_EMPTY);
print $data[1];//the second item

But for this job explode() is still way faster than both, because it doesn't need to faff around with building a finite automaton to run the regexp.
