add code for today date in my php class/function

Good day!

I want to know what is the syntax for date(dd-mm-yyyy) and how can I insert it to my code:

PHP:

$Mail->Subject = 'Preview/' . $this->csvUploadPaymentDetails[0]['csvfilename'];


Sorry, because I'm not familiar with class and function.

i want toe result is Preview/Filename/Date/

Thank you so much
