我已经阅读了一些关于此问题的不同主题（like this one以及关于uasort()的一般文档信息 - 我相信这是我正在寻找的内容），但数组仍然是有点顽固（在我的用例中）。
这就是我所拥有的：
// This sets an array of values to a variable
$collection_rows = get_field('collection_profiles');
这是print_r的{{1}}：
$collection_rows（非常糟糕）
我希望按Array

的数组键/值排序。我所尝试的（到目前为止）是：
collection_profile_note虽然它确实更改了显示的顺序而没有$collection_rows = get_field('collection_profiles');
print_r($collection_rows);
if ($collection_rows) {
echo '<h2>'.__('Profiles in Collection','roots').'</h2>';
echo '<ul>';
function cmp($a, $b) {
if ($a->collection_profile_note == $b->collection_profile_note) {
return 0;
} else {
return $a->collection_profile_note < $b->collection_profile_note ? 1 : -1;
}
}
usort($collection_rows, 'cmp');
foreach($collection_rows as $collection_row) {
// Extract single post value
$collection_profile_field = $collection_row['collection_profile'];
$collection_profile_page = isset($collection_profile_field[0]) ? $collection_profile_field[0]->ID : NULL;
?>
<li><a href="<?php echo get_permalink($collection_profile_page); ?>"><?php echo get_the_title($collection_profile_page); ?></a> <?php echo $collection_row['collection_profile_note']; ?></li>
<?php }
echo '</ul>';
}
，但它没有按照我想要的顺序排序 - ＆gt;功能（2,3,1），无功能（1,3,2）
非常感谢任何帮助。谢谢！

好吧，你已经向后实施了排序逻辑：
function cmp($a, $b) {
if ($a->collection_profile_note == $b->collection_profile_note) {
return 0;
} else {
return $a->collection_profile_note < $b->collection_profile_note ? 1 : -1;
}
}
function cmp($a, $b) {
if ($a == $b) {
return 0;
}
return ($a < $b) ? -1 : 1;
}
请注意，您正在使用此逻辑：

您是否有必要对阵列进行排序？可能更容易打破你正在排序的键和值，对它们进行排序，然后循环遍历该数组（如此）：
$sortme=array();
foreach( $collection_rows as $key=>$profile )
{
$sortme[$key] = $profile['collection_profile_note'];
}
asort($sortme);
foreach( $sortme as $node=>$ignore )
{
print_r($collection_rows[$node]);
}
承认这几乎是整理时间的两倍，但也许足以满足您的需求？
