Question

I think of a syntax like:

$suffix1 = ($a === 1) ? 'this is one.' : 'this is:'
   foreach ($keywords as $keyword) {
       ' and '
       .$keyword
  };

what should be like in case of $a === 1 output: this is one.
in case of not $a === 1 output: this is: one and two and three…

$keywords

comes from a input type text and will be splitted by:

$sepkeywords = preg_split('/[\s]+/', $keywords);

so if there is someone who could tell me how to get this i really would appreciate.

Answer 1

Are you looking for implode function?

$suffix1 = ($a === 1) ? 'this is one.' : 'this is: ' . implode(' and ', $keywords);
