Converting php date to fit mysql database

I want to convert an input date in the form 开发者_如何学Cof dd/mm/yyyy to the MySQL format which is yyyy-mm-dd.

I was trying to use date('Y-m-d', strtotime($_POST['date'])) but the problem is that the output is always Y-d-m, I think because it considers my 2nd argument to be mm/dd/yyyy.

How do I solve that?

date('Y-m-d', strtotime(str_replace('/', '-', $_POST['date'])))

From the manual:

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.

You need to convert your delimiters from / to -.

You could do:

$date = implode('-', array_reverse(explode('/', trim($_POST['date']))));

Reference: trim, explode, array_reverse, implode

(trim might not be necessary)

Mohamed,

I would recommend not even formatting the date in the database. If you store all of your date / time values as UNIX TIMESTAMP, you can format the data any way you want after you pull it from the data base.

Here's why: If all of your dates are formatted and you need to compare them, you'd need to bring them back to UNIX TIMESTAMP anyways. Yes, there are wheres to compare formatted date strings but its just one more extra step.

Although this is a bit late : If he uses timestamps then, in my experience he will run into trouble if he tries to perform any MySQL Date arithmetic / calculations on the timestamps - and the over head to do the same in PHP has the potential to become very expensive as it would involve selecting ALL records and then performing comparisons / calculations on the converted dates.

And I concur with jasonbar - PHP is looking at the delimiters of the date and considers it to be a US format date! He will need to run a str_replace('/','-',$_POST['date']) BEFORE using the date() function.

So, to fix this on an incoming request:

$mysqldate = date('Y-m-d', str_replace('/','-',strtotime($_POST['date'])));

So long as the data type for the target column is datetime anyways!

I found a pretty simple conversion.

$YOUR_DATE_FORMAT YYYY/MM/DD  

$date = strtotime($YOUR_DATE_FORMAT); 

$newdate = date('Y-m-d', $date); //or whatever format you choose. 

works like a charm.
