Plain english?

[djoxer]

I'm a newbie at PHP so I apologize for the dumb question.  Can anyone please explain to me in plain english what these two lines are asking for?

 

if ($line!="*\r\n")

 

if (($line_num%2)==0)

 

Thanks

In first line if condition is true only when $line variable is not equal to string *\r\n

 

in other line if condition is true only when reminder of ($line_num%2) is equal to 0

to elaborate a little more, the '%' means Modulus, that is, the remainder of a division. e.g 2%2 = 0; 3%2 = 1;

One more question:  What does *\r\n mean?  Is it similar to chr(10)chr(13)?

 

Thanks for your help.

its a string  containing  those:

\r or  "carriage return" or chr(10) (like you said)

\n or "newline character" or chr(13) (like you said)

 

 

I dont know exactly what it means with out seeing all of the code, it looks like some sort of regex thing.
