Just because a function is named foo in PHP doesn't mean it's named foo in perl.
As a matter of fact Perl has: pop <-- returns the top of an array and deletes it -- like array_pop push <-- puts something into an array shift <-- returns the bottom of the array and deletes it unshift <-- puts something into the bottom of the array With the above functions and arrays and hashes there are very few data structures you can't create in a few minutes. Also, PHP is a very different language then Perl, remember that. And PHP has a lot of problems. I personally moved over to Perl after we got sick of having to recompile PHP every time we wanted to use a new function (Perl's modules work great). It's actually kind of interesting. If you look at what PHP is trying to do with PHP 5 it is basically trying to copy a lot of Perl's object oriented system. But both languages are great. Languages are like tools. Not all problems are nails, so if you see a screw you might need to use a screwdriver (Perl), or if you see a bolt you might need a wrench (LISP), etc. -Dan On Wed, 2003-11-12 at 14:44, John Dillon wrote: > > perldoc > > > What he means is http://www.perldoc.com/ or something else, like something on c: or > a terminal window. > > This is good.
