functions

[incarnate]

is there a function that does the exact opposite of the strstr() function?

why not search it at PHP Manual?

I had this problem! And I never got it to work quite perfectly. I ended up with strrchr() or something that didn't quite do it. I don't know. It was awhile ago, but it was used to grab a glob of text between the closest tags, something I couldn't figure out how to do with regex. I always ended up with the largest spanning match.

Heh, good idea.

incarnate, there's quite a list of stuff on that page, one might do what you want. By 'exact' opposite, I assume you mean find the last occurence of a string in a string? I mean, it could be "lose the last non-occurence of an integer in an array" or somesuch, couldn't it?

Heh, how 'bout

$needle="fred";
$needle=strrev($needle);
$haystack="Fred, you were a good dog, oh, fred, come home";
$haystack=strrev($haystack);
$term=strstr($haystack, $needle);
$term=strrev($term);

Magic. Why didn't I just turn the string around instead of trying to go backwards? Someone ought to mark this resolved. Also, as another note, that would not have been in the PHP Manual as it's not a function. I really think that only people who know the answer have the right to say RTFM if it's the bleeding obvious. Then again, this is the n00bs forum, right?

Mebbe. He never said exactly what he was hunting for. In my very simple example, it wouldn't really matter, would it?

Nonetheless, thinking backwards can occasionally do some good. It's nice to be crazy..... 😃

Hey, now it IS a function...!

function revstrstr($needle, $haystack) {
    $needle=strrev($needle);
    $haystack=strrev($haystack);
    $term=strstr($haystack, $needle);
    $term=strrev($term);
    return $term;
}
