访问POST数据

Question

I'm very new to PHP but have a good understanding of C,

When I want to access some post data on an API i'm creating in PHP I use:

 $_POST['date_set']

to fetch a value being passed for date - This all works perfectly, however I read I should be fetching it like this:

$date_set = trim(urldecode($_POST['date_set']));

This always returns a 00:00:00 value for the date after it's stored in my DB.

When I access directly using $_POST['date_set'] I get whatever value was posted, for example: 2013-08-28 10:31:03

Can someone tell me what I'm messing up?

Answer 1

You only run urldecode over data is URL encoded. PHP will have decoded it before populating $_POST, so you certainly shouldn't be using that. (You might have to if you are dealing with double-encoded data, but the right solution there should be to not double encode the data).

trim removes leading and trailing white-space. It is useful if you have a free form input in which rogue spaces might be typed. You will need to do further sanity checking afterwards.
