Probably because while the answer is correct, it answers an obviously duplicate, obviously help-vampiric, obviously something-you-shouldn't-answer question. The community expects a 34k user to vote to close the question, instead of answering it. – Madara's Ghost Mar 03 '14 at 10:27

You could use something like:

date("F j, Y", time() - 60 * 60 * 24);

You assume a day is 86400 seconds long. – Maerlyn Mar 03 '14 at 10:04
@Maerlyn I guess it depends on which planet you are from. On mine a day is 86,400 seconds long – Steve Mar 03 '14 at 10:06

Every day? Surely not, just think about when you switch to/from DST. – Maerlyn Mar 03 '14 at 10:27
@Steve - Not all Australian states have daylight savings, but a blanket statement that `a day is 86,400 seconds long` doesn't hold for all parts of your own country, let alone the world – Mark Baker Mar 03 '14 at 11:56
All true...I concede :o) – Steve Mar 04 '14 at 07:56

You can also use DateTime:

$date = new DateTime('');
$date->modify('-1 day');
echo $date->format('Y-m-d') . "\n";
