Just a note to self, after running around in google search circles for a bit…
function array_sort_by($key, array &$array)
{
return usort($array, function($x, $y) use ($key)
{
return strnatcasecmp($x[$key] ?? null, $y[$key] ?? null);
});
}
{
return usort($array, function($x, $y) use ($key)
{
return strnatcasecmp($x[$key] ?? null, $y[$key] ?? null);
});
}
Uses ?? null in case key doesn’t exist on some items.
Switch to strnatcmp if you want case-sensitive sorting.
