PHP - 将日期转换为YYYY-MM-DDTHH：MM：SS

Question

I was wondering if it was possible to format todays date to below format:

YYYY-MM-DDTHH:MM:SS

It's important that the "T" is preserved, like this:

2017-07-20T00:00:00

Below I have:

$invoice_date = date('Y-m-d H:i:s');

I can't figure out how to add the "T" in between.

Answer 1

T is a format character so you can't use it directly. Escape it (\T) to get a literal T character:

You can prevent a recognized character in the format string from being expanded by escaping it with a preceding backslash.

$invoice_date = date('Y-m-d\TH:i:s');
