PHP date outputting incorrect month -

-

if pass example ?month=$04 in url , echo $date keep receiving january , not should (april). if echo out $month 04 correct. code have been using:

if (isset($_get['month']) && $_get['month']!='') {         $month = $_get['month'];         $date = date('f', $month); }  echo $date;

for life of me can't figure out why it's not outputting correctly. appreciated.

look @ you're doing here:

date('f', '04');

the second parameter date() timestamp, starting january 1st, 1970. doing specifying january 1st, 1970, 00:00:04 hours midnight.

what want achieved e.g. so:

$timestamp = strtotime ("2000-$month-01"); // 2000-04-01 april echo date('f', $timestamp);

(in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
