我有一个如下所示的数组。 目前，它按 OwnerNickName 字段的字母顺序排序。 现在我想将包含 OwnerNickName 'My House' 的数组条目作为数组的第一个条目，并按 OwnerNickName 的字母顺序排序。 有什么想法吗？

最佳答案
您可能想实现自己的排序功能，例如:
function cmp($a, $b)
{
if ($a['OwnerNickName'] == $b['OwnerNickName']) {
return 0;
}
if ($a['OwnerNickName'] == 'My House') {
return -1;
} else if ($b['OwnerNickName'] == 'My House') {
return 1;
}
return ($a['OwnerNickName'] < $b['OwnerNickName']) ? -1 : 1;
}
usort($array, 'cmp');
