How to create a string equivalent to yyyyMMddHHmmssffff in PHP?

Question

I'm trying to integrate with some VB code that uses DateTime.Now.ToString("yyyyMMddHHmmssffff") to generate a string.

DateTime.Now.ToString("yyyyMMddHHmmssffff")

The closest I can get to this in PHP is:

date('YmdHis')

But this is missing the millisecond part.

I have tried using microtime, for example:

date('YmdHis',time()).substr(str_replace(".","",microtime(true)),10,17)

But sometimes this results in a shorter string.

Answer 1

date The function always returns zero for microseconds. You can use the DateTime->format function and remove the last two digits to retain 4 decimal places.

substr((new DateTime()) -> format('YmdHisu'), 0, 18);
