Split the sentence on spaces, reverse the array, and join them on spaces:

echo implode(' ', array_reverse(explode(' ', $str)));

What about the case? Does it change uppercase I to lowercase `i` ? And also it displays `Google.` instead of `Google`. – Avinash Raj Nov 06 '14 at 08:40

You should do it like this:

split the string into array of words
rearrange the array into the sequence you need
join the array back into a string.
