Hi There,
I have never used hashes before, althought they seem to be interesting I didn't
know the exact use for it. But as times are changing I think I just came to a point
where I need a hash, but how do I create one and how do I use it ?
Can anyone assist ? this is what I want to accomplish :
foreach(HASH) {
if (($pdf1) && ($link1)) {
exec("ln -s ${link1} ${base}/${pdf1}");
} # End if
} # End foreach
So I have 2 variables that always come together. To write an if then statement
for 10 times because I have 10 * pdf and link variables looks bad to me.
So I am looking for the foreach HASH something. I know it must be possible.
Who can assist ?
Plus, how do I fill a HASH ?? : " HASH = ($pdf1, $link1); "?? How to proceed
with my next " HASH[1] = ($pdf2, $link2); " ??
Thanks for your help in advance !!!
