Search for word by position

[srarcade]

Is it possible to search for a word by its position on a line?

Lets say I have the following:
$comment = 'Hello world the sentence';

Is there a function that will return a word I specify like if I wanted word 2, it would return 'world' or if i wanted word 4, it would return 'sentence'?

Thanks

[man]explode[/man] the string
Then search the resulting away for the word.

Remember that the first element will be [0].

To find word 4:

$comment = 'Hello world the sentence';
$myarray=explode(' ', $comment);
$word4=$myarray[3];
