Closed 8 years ago.
I'm trying to reorganize my array orderned by date.
For example this is my array:
Array(
[0] => august
[1] => july
[2] => october
[3] => september
)
How can i reorganize it chronologically, so it would become this:
Array(
[0] => july
[1] => august
[2] => september
[3] => october
)

Answer 1

Use date_parse to parse the month name and convert it to the corresponding number and then use ksort to sort them.
$myArray = array('august', 'july', 'october', 'september');
foreach($myArray as $value) {
$m = date_parse($value);
$output[$m['month']] = ucfirst($value);
}
ksort($output);
print_r($output);
Output:
Array
(
[7] => July
[8] => August
[9] => September
[10] => October
)

Answer 2

This should work for any date that strtotime can parse
function cmp($a, $b)
{
$a_time = strtotime($a);
$b_time = strtotime($b);
if ($a_time == $b_time) {
return 0;
}
return ($a_time < $b_time) ? -1 : 1;
}
// Array to be sorted
$array = array('november', 'august', 'december', 'february');
print_r($array);
// Sort and print the resulting array
usort($array, 'cmp');
print_r($array);
Output:
Array
(
[0] => november
[1] => august
[2] => december
[3] => february
)
Array
(
[0] => february
[1] => august
[2] => november
[3] => december
)
