Dates in the m d y or d-m-y formats are disambiguated by looking   at the separator between the various components  if the separator is a   slash      then the American m d y is assumed  whereas if the   separator is a dash  -  or a dot      then the European d-m-y   format is assumed  Check more here    Use the default date function    var    20 04 2012   echo date  Y-m-d   strtotime  var       EDIT I just tested it  and somehow  PHP doesn t work well with dd mm yyyy format  Here s another solution    var    20 04 2012    date   str replace       -    var   echo date  Y-m-d   strtotime  date

Do this   date  Y-m-d   strtotime  dd mm yyyy       But make sure  dd mm yyyy  is the actual date

I can see great answers  so there s no need to repeat here  so I d like to offer some advice   I would recommend using a Unix Timestamp integer instead of a human-readable date format to handle time internally  then use PHP s date   function to convert the timestamp value into a human-readable date format for user display  Here s a crude example of how it should be done      Get unix timestamp in seconds  current time   date        Or if you need millisecond precision     Get unix timestamp in milliseconds  current time   microtime true     Then use  current time as needed in your app  store  add or subtract  etc   then when you need to display the date value it to your users  you can use date   to specify your desired date format      Display a human-readable date format echo date  d-m-Y    current time     This way you ll avoid much headache dealing with date formats  conversions and timezones  as your dates will be in a standardized format  Unix Timestamp  that is compact  timezone-independent  always in UTC  and widely supported in programming languages and databases

Try Using DateTime  createFromFormat    date   DateTime  createFromFormat  d m Y    24 04 2012    echo  date- gt format  Y-m-d      Output   2012-04-24   EDIT   If the date is 5 4 2010  both D M YYYY or DD MM YYYY   this below method is used to convert 5 4 2010 to 2010-4-5  both YYYY-MM-DD or YYYY-M-D  format    old date   explode       5 4 2010      new data    old date 2   -   old date 1   -   old date 0     OUTPUT   2010-4-5
