add code for today date in my php class/function

[rhodarose]

Good day!

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

$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

How can I add this code:

$this->csvUploadPaymentDetails[0]['week_num'] 

with this code:

$Mail->Subject = 'Preview/' . $this->csvUploadPaymentDetails[0]['csvfilename'] .'/'.date('d-m-Y'); 

to make the subject become:

Preview/Filename/Date/Week No

Thank you
