Sorting files by creation/modification date in PHP [duplicate]

Answer 1

You can store the files in an array, where the key is the filename and the value is the value to sort by (i.e. creation date) and use asort() on that array.

$files = array(
    'file1.txt' => 1267012304,
    'file3.txt' => 1267011892,
    'file2.txt' => 1266971321,
);
asort($files);
var_dump(array_keys($files));
# Output:
array(3) {
  [0]=>
  string(9) "file2.txt"
  [1]=>
  string(9) "file3.txt"
  [2]=>
  string(9) "file1.txt"
}
