如何用scandir（）对数字上升进行排序

Question

Just like the question asks. Does 5.4 address this?

Answer 1

array scandir ( string $directory [, int $sorting_order = SCANDIR_SORT_ASCENDING [, resource $context ]] )

but SCANDIR_SORT_ASCENDING will not work properly with numerical names. You can foreach items and then sort them with other function like this one: sort($array, SORT_NUMERIC)

Answer 2

Yes, I am using scandir(); To make it sort Descending rather than the default Ascending, use the int 1 or 0.

scandir(directory,sort,context);

for example:

$dir = "./portfolio"; 
$files = scandir($dir, 1);

Answer 3

Yes, see docs http://php.net/manual/en/function.scandir.php

As of version 5.4.0

sorting_order now accepts constants. Any nonzero value caused descending order in previous versions.
