This is good. I've learnt something...like when perl people say something, stick it in google and see what comes up. Let's see how the search for (web) solutions compares between perl and php. Searching 'array' on this - perldoc - gives: http://www.perldoc.com/cgi-bin/htsearch?words=array&restrict=perl5.8.0 (it's a list of questions - you need to look at the link.) By comparison, searching on php.net gives: http://uk2.php.net/manual/en/function.natcasesort.php (it includes a list of functions.) OK, both are interesting. Search on 'array_pop', for instance - an slightly important function in form processing, on this link on php.net gives: http://uk2.php.net/manual/en/function.array-pop.php Choosing the first listed choice, perlfq4, on the perdoc.com link gives: http://www.perldoc.com/perl5.8.0/pod/perlfaq4.html OK. Now, 'array_pop' is the (php) function which deletes an element from the end of the array. So, where is this on perl (I know that's unfair, I should go the other way also - see below)? The link on perldoc says blah blah blah in a rather two dimensional way and fails: a.. Data: Arrays a.. What is the difference between a list and an array? b.. What is the difference between $array[1] and @array[1]? c.. How can I remove duplicate elements from a list or array? d.. How can I tell whether a certain element is contained in a list or array? e.. How do I compute the difference of two arrays? How do I compute the intersection of two arrays? f.. How do I test whether two arrays or hashes are equal? g.. How do I find the first array element for which a condition is true? h.. How do I handle linked lists? i.. How do I handle circular lists? j.. How do I shuffle an array randomly? k.. How do I process/modify each element of an array? l.. How do I select a random element from an array? m.. How do I permute N elements of a list? n.. How do I sort an array by (anything)? o.. How do I manipulate arrays of bits? p.. Why does defined() return true on empty arrays and hashes? a.. Data: Hashes (Associative Arrays) a.. How do I process an entire hash? b.. What happens if I add or remove keys from a hash while iterating over it? c.. How do I look up a hash element by value? d.. How can I know how many entries are in a hash? e.. How do I sort a hash (optionally by value instead of key)? f.. How can I always keep my hash sorted? g.. What's the difference between "delete" and "undef" with hashes? h.. Why don't my tied hashes make the defined/exists distinction? i.. How do I reset an each() operation part-way through? j.. How can I get the unique keys from two hashes? k.. How can I store a multidimensional array in a DBM file? l.. How can I make my hash remember the order I put elements into it? m.. Why does passing a subroutine an undefined element in a hash create it? n.. How can I make the Perl equivalent of a C structure/C++ class/hash or array of hashes or arrays? o.. How can I use a reference as a hash key? Now, I'm not tempted to pursue any of those lines of enquiry, as they don't appear to answer my question (or rather ask my question). At this stage I would ask the group. I mean these are good - many are questions I have come up against in web coding. But I want a list of perl functions. That might be the shortest way to the solution. So, that didn't work in perldoc - let's give the advantage to perl and start with a perl link: How do I reverse a string? Use reverse() in scalar context, as documented in perlfunc/reverse. OK, and check against php.net: http://uk2.php.net/manual-lookup.php?pattern=How+do+I+reverse+a+string%3F+&lang=en not very helpful. That says something...like perl started as a string and other things manipulation extraction language - I mean how often do you want to reverse a string in web design? - whereas php started as a HTML manipulation language and is good for database interaction, for which arrays are important.
