• PHP-MYSQL: Converting Unix Timestamp to DateTime and vice versa 5 answers

Im currently struggeling with timestamps. I have Googled for a simple answer for this, but cant find any solution for my problem. I want to convert user input into UNIX time. The user inputs for example "26/03/1982", how do I convert this input into UNIX timestamp?

//User input
$birthday = "26/03/1982"; // d/m/y
$birthday = [CONVERTED TO UNIX]

Short and simple question. I will add more if you'd like. Thanks.

Answer 1

Look into the PHP function strtotime:

strtotime — Parse about any English textual datetime description into a Unix timestamp

I'm not sure how well it handles / in dates, but replace them with - and it'll work.

Example

echo strtotime(str_replace("/","-","26/03/1982"));

outputs 385977600 which is the Unix date for Fri, 26 Mar 1982

You may need to set your date_default_timezone for this to work
