Here is a little sample to do fast hierarchical queries using new prepared statements
<?php
// Root - lowest start element
// Top - most top element
// stack - array for storing info
function tree_rise($root, &$stack, $top = 0) {
$mysqli = mysqli_connect('localhost', 'root');
$top = (int)$top;
$stmt = mysqli_prepare($mysqli, "SELECT id, pid, title FROM news.strg WHERE id = ? LIMIT
1");
mysqli_stmt_bind_param($stmt, "i", $root);
mysqli_stmt_execute($stmt);
mysqli_stmt_store_result($stmt);
mysqli_bind_result($stmt, $id, $root, $title);
while (mysqli_fetch($stmt)) {
$stack[$id] = $title;
if ($root != $top && !is_null($root)) {
mysqli_stmt_execute($stmt);
mysqli_stmt_store_result($stmt);
}
}
return count($stack);
}
?>
