PHP标准库(SPL)学习之SplMinHeap

学习了SplHeap与SplMaxHeap后就应该知道SplMinHeap其实就是SplMaxHeap的倒叙.

代码如下

<?php
$heap = new SplMinHeap();

$heap->insert(100);
$heap->insert(100.1);
$heap->insert(200);
$heap->insert(400);

$heap->rewind();

while ($heap->valid()) {
    echo $heap->current().PHP_EOL;
    $heap->next();
}
