你如何用PHP重新安排约会（09-09-2013）到（2013-09-09）？ [重复]

Question

This question already has an answer here:

• Convert one date format into another in PHP 15 answers
• Convert date format yyyy-mm-dd => dd-mm-yyyy 14 answers

I am trying to figure this out, I am not the php developer, but I was tasked with this anyways. So, I have been trying to figure it out. I have been asked to replace the - with commas, and rearrange the dates. For example mm-dd-yyy to yyyy-mm-dd

This is how I replace the -

$TheDate = "09-09-2013";
$TheDate = str_replace('-', ',', $TheDate);
echo $TheDate;

Now, the problem is that I don't even know where to start on how to rearrange the numbers. Could someone please lead me in the right direction?

Answer 1

Use php date() and strtotime() to do this. It's the slandered way.

echo date('Y-m-d',strtotime('09-09-2013'));
