[Year 12 SofDev] Arrays with mixed data types

[Howard, David]

They are most like a Hash in Ruby, or an assoc array. They can have multiple data types in them. It's one of the many reasons why it is known as a loosely typed language.

Subject: Re: [Year 12 SofDev] Arrays with mixed data types

I'm not familiar with the inner workings of PHP, but my research suggests their 'arrays' are not exactly the same nature as most other languages.

It's sort of like when TV guides categorise 'Big Brother' as 'entertainment' ... a non-classical use of the term.

I ask because I'm writing an exam with a question about whether a 2D array with mixed data types is possible (or wise).

Cheers
Mark

Hi, codemakers.

Most languages require all elements of an array to have a single data type, but I have a nagging suspicion that there is an exception or two.

e.g. Apparently PHP allows mixed data types in its 'arrays' but I believe PHP 'arrays' are actually more like the lists found in Perl or Python and so are not classical arrays.

Is there a language that allows true arrays with mixed data types?

Cheers
Mark
