Loop pages in ProcessWire without building a $pageArray. This is useful for when a find() would return too many results to keep in memory.

allternativeLoopPW.php

$selector = "template=pages_template"; // as an example

while (1) {
    $p = wire('pages')->get("{$selector}, id>$id"); // get page with id bigger than previous
    if(!$id = $p->id) break; // assign current page's id to $id or break the loop if it doesn't exist

    // do stuff using $p as the current page 
    
    wire('pages')->uncacheAll(); // clean the memory (with $p->uncache() doesn't work. why?)
};

The initial $id is missing here.
