php - Scandir variable not a string? -

-

i have piece of php code lists directories , creates div's information regarding directories inside of it. when $newspieces[i] doesn't include name of folder in string, why?

<?php     $newspieces = scandir("posts");     ($i = 2; $i < count($newspieces) , $i < 10; $i++) {         $titlefile = fopen($newspieces[i] . "/title.txt", "r");         $textfile = fopen($newspieces[i] . "/text.txt", "r");         $fullelement = "<div class='newspiece'><div class='newsimageholder'><img class='newsimage' src='" . $newspieces[i] . "/image.jpg'></div><div class='newscontent'><h1 class='newstitle'>" . fread($titlefile, filesize($newspieces[i] . "/title.txt")) . "</h1><p class='newstext'>" . $piece[] = fread($textfile, filesize($newspieces[i] . "/text.txt")) . "</p><a class='newslink' href='post?post=" . urlencode($newspieces[i]) . "'>continue reading</a></div></div>";         echo $fullelement;         fclose($titlefile);         fclose($textfile);     } ?>

fixed version:

<?php     $newspieces = scandir("posts");     ($i = 2; $i < count($newspieces) , $i < 12; $i++) {         $titlefile = fopen("posts/" . $newspieces[$i] . "/title.txt", "r") or die("unable open file!");         $textfile = fopen("posts/" . $newspieces[$i] . "/text.txt", "r") or die("unable open file!");         $fullelement = "<div class='newspiece'><div class='newsimageholder'><img class='newsimage' src='posts/" . $newspieces[$i] . "/image.jpg'></div><div class='newscontent'><h1 class='newstitle'>" . fread($titlefile, filesize("posts/" . $newspieces[$i] . "/title.txt")) . "</h1><p class='newstext'>" . fread($textfile, filesize("posts/" . $newspieces[$i] . "/text.txt")) . "</p><a class='newslink' href='post?post=" . urlencode($newspieces[$i]) . "'>continue reading</a></div></div>";         echo $fullelement;         fclose($titlefile);         fclose($textfile);     } ?>

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
