write a analoghrim in php to write the text..

[webandwe]

Hi,

I was just wondering I saw the following question in a test once and now it bug me...

The question was:

Write a analoghrim in php to write the text "word1 word2 word3 word4" to "word4 word1 word2 word3".


Yes I also at first thought they wanted you to write the text backwards but as you can see they swaped the words around a bit?

Can someone just explain to me what must happen here cause I will just write it or put a button there and in my code say " if button was press echo..word bla bla bla;

Thanks

Hi.

If they want you to write an algorithm I would assume they wanted you to sort the elements based on some mathematical rule. Tho I can not see what that may be.

Perhaps they wanted you to hard-code it to return them this way, or perhaps they wanted them returned randomly?
Maybe they wanted them returned in reverse order and they made a typo?

Try asking the people who set you the test what exactly they mean, if that is possible.

Heya, Webandwe.

PHP has a useful function for splitting a string into an array. From there, it's a simple matter of reversing the array (also a built-in function for that) and then turning the array back into a string (yup, there's a built-in for that as well).

I would imagine that the instructor who assigned this problem would have wanted you to use a for or foreach loop to copy the elements of the array into another array before joining the elements back into a string, but now you know why I'm so bad at school 0:)
