What I had to learn about perl:
open files
For writing
open(FILE, ">"."$filename"); print(FILE "hello world");
functions with parameters
In any function (sub) you can access the parameters only via
$_[0]
for the first parameter
$_[1]
for the second parameter and so on.
preg_replace
Preg_replace in perl works like this:
$url =~ s\http://\\g;
$url then contains what was in before, but without http://
