Re: Help with PHP-to-Perl CPAN bundle

Hrm. Embperl perhaps, though for small to middle sized sites, HTML::Template is preferable.

PHP has mysql functions built in, so DBI and the mysql driver are a good pick. However, the DBI framework is again a little bit more involved, and is object oriented, so perhaps not the best pick for a PHP convert. Anyone know of a purely procedural equivalent, mysql only?

Other than that, PHP has some HTML manipulating functionality, and that's about it. CGI.pm has the escapeHTML function, and HTML::Scrubber I believe should do the rest.

The pretty much covers functionality that PHP posesses that Perl doesn't, but it doesn't cover that you don't have to import any of these things in PHP. You may consider creating a wrapper module to include this functionality, or even provide same name functionality for the Perl scripts. Then again, if you're teaching classes, then teaching the language and the modules is probably better than making them learn a throw off framework designed to imitate another language.

There are some difference that you'll need to make PHP developers aware of, kind of a cheat sheet.

Ignore function prototypes in Perl, they don't work like you think they work. This is one of two features that I miss in Perl when coming back from PHP.
foreach my $alias (@array) creates an alias to the @array entry. Mutiple aliases in the loop aren't possible. (In PHP you can do for ($hash => $key, $value) {...} to do multiple aliases)
Arrays and Hashes are not the same data structure, and hashes do not preserve order.
Perl has a debugger! Rejoice!

Cheers,

PHP has a couple of debuggers by dazzle (Sexton) on Sep 28, 2004 at 21:32 UTC
Forgive me, fellow monks, I have been touching up the documentation for the Advanced PHP Debugger (APD) recently after attending George Schlossnagle's profiling session at php\|works 2004. There's also Xdebug, which Derick Rethans develops and maintains. It's used for the debugging support in Komodo, for one. One of the things I found at php\|works is that the people who actually develop the language don't tend to have fanatical devotion to their language; instead, they look at other languages as tools, each of which might be more suited for a particular job than another, and each of which has something that they might learn from and adapt (or evolve) for their own language. Quite refreshing. I'm looking forward to YAPC 2005! Oh, another item for the cheat sheet: the & sigil means very different things in Perl and in PHP. You know what it does in Perl, but in PHP the & means "pass this by reference". You can prepend it to a variable when you pass it into a function, or assign it to another variable, or you can prepend it to the variable name in a prototype so that you always get the reference to the object being passed in.

the DBI framework is again a little bit more involved, and is object oriented, so perhaps not the best pick for a PHP convert. Anyone know of a purely procedural equivalent, mysql only? interestingly, the new mysqli interface in php5 adds oo and is similar to DBI. perl -e"\$_=qq/nwdd\x7F^n\x7Flm{{llql0}qs\x14/;s/./chr(ord$&^30)/ge;print"	[reply]

foreach my $alias (@array) creates an alias to the @array entry. Mutiple aliases in the loop aren't possible. (In PHP you can do for ($hash => $key, $value) {...} to do multiple aliases) Unless I'm misunderstanding this (not knowing PHP), then what you are looking for here is each. eg: `while (my ($key, $value) = each %hash ) { .. }` [download] Or am I way off the mark?

`$key, $value` are copies of the values in the hash. The => operator can be used in PHP to create aliases to the elements, so changing `$value` is the same as changing `$hash{$key}` (to use Perlish syntax). So, in PHP: `$array = (0,1,2,3,4,5); for ($array => $a, $b, $c) { $c = 'two'; } print ($array[2]) #Prints 'two'` [download] Cheers, Erik Light a man a fire, he's warm for a day.
