Question

I want to get an numeric array out of Set::combine in cakePhp.

Set::combine($results, '{n}', '{n}.Tag.name')

But this doesn’t work as I expected because ‘{n}’ is Array and not the index, like I thought. This doesn’t work neither

Set::combine($results, '', '{n}.Tag.name') 
//OR
Set::combine($results, '{n}.Tag.name')

In the documentation http://book.cakephp.org/2.0/en/core-utility-libraries/set.html I didn’t find anything that helped me.

Is it possible to use Set::combine to get an array in the same numeric order like it is passed into the function keeping the numeric keys or do I have to transform the keys in another way?

Answer 1

I found the function Set::classicExtract that works!

 Set::classicExtract($results, '{n}.Tag.name')
