Question

I am using glob() php function to find the files in a directory.
I am getting the following array as result:

Array
(
[0] => D:\xampp\htdocs\myproject\app\webroot\batch\temp\file_2012-08-09-0.jpeg
[1] => D:\xampp\htdocs\myproject\app\webroot\batch\temp\file_2012-08-09-1.jpeg
[2] => D:\xampp\htdocs\myproject\app\webroot\batch\temp\file_2012-08-09-10.jpeg
[3] => D:\xampp\htdocs\myproject\app\webroot\batch\temp\file_2012-08-09-11.jpeg
[4] => D:\xampp\htdocs\myproject\app\webroot\batch\temp\file_2012-08-09-2.jpeg
[5] => D:\xampp\htdocs\myproject\app\webroot\batch\temp\file_2012-08-09-3.jpeg
[6] => D:\xampp\htdocs\myproject\app\webroot\batch\temp\file_2012-08-09-4.jpeg
[7] => D:\xampp\htdocs\myproject\app\webroot\batch\temp\file_2012-08-09-5.jpeg
[8] => D:\xampp\htdocs\myproject\app\webroot\batch\temp\file_2012-08-09-6.jpeg
[9] => D:\xampp\htdocs\myproject\app\webroot\batch\temp\file_2012-08-09-7.jpeg
[10] => D:\xampp\htdocs\myproject\app\webroot\batch\temp\file_2012-08-09-8.jpeg
[11] => D:\xampp\htdocs\myproject\app\webroot\batch\temp\file_2012-08-09-9.jpeg
)

What I want is “To sort the files on the basis of partial text of file names”. As in the above array, when you may realize I was supposed to expect the result to be sorted as the ...-0.jpeg, ...-1.jpeg, ...-2.jpeg not ...-0.jpeg, ...-1.jpeg, ...-10.jpeg.

I am expecting the following result:

Array
(
[0] => D:\xampp\htdocs\myproject\app\webroot\batch\temp\file_2012-08-09-0.jpeg
[1] => D:\xampp\htdocs\myproject\app\webroot\batch\temp\file_2012-08-09-1.jpeg
[2] => D:\xampp\htdocs\myproject\app\webroot\batch\temp\file_2012-08-09-2.jpeg
[3] => D:\xampp\htdocs\myproject\app\webroot\batch\temp\file_2012-08-09-3.jpeg
[4] => D:\xampp\htdocs\myproject\app\webroot\batch\temp\file_2012-08-09-4.jpeg
[5] => D:\xampp\htdocs\myproject\app\webroot\batch\temp\file_2012-08-09-6.jpeg
[7] => D:\xampp\htdocs\myproject\app\webroot\batch\temp\file_2012-08-09-7.jpeg
[8] => D:\xampp\htdocs\myproject\app\webroot\batch\temp\file_2012-08-09-8.jpeg
[9] => D:\xampp\htdocs\myproject\app\webroot\batch\temp\file_2012-08-09-9.jpeg
[10] => D:\xampp\htdocs\myproject\app\webroot\batch\temp\file_2012-08-09-10.jpeg
[11] => D:\xampp\htdocs\myproject\app\webroot\batch\temp\file_2012-08-09-11.jpeg
)

Kindly help, how I can do it using PHP with/without regular expression?

Answer 1

Use natsort function that sort an array using a “natural order” algorithm
